Flame retardants for plastics main contents are as follows:
(1) through the viscosity of the test to study the flame retardant type and content on the rheological properties of the resin. High dosage of flame retardant to make rapid increase in the viscosity of mixed system, we use to add viscosity reducer and styrene dilution methods to reduce the viscosity.
(2) by gel time, peak time and temperature of the test to determine the molding process conditions studied flame retardant type and content on the reactivity of the resin.
3) by means of horizontal and vertical burning (UL-94), limiting oxygen index (LOI) and smoke density test, study the types and dosage flame retardant properties of materials, analysis of different complex flame retardants retardant effect. The results showed that: the same dosage
When, APP flame efficient, followed by DEEP, ATH flame retardant least efficient; while at the same ratio, ATH / DEEP complex system synergistic flame retardant effect than the ATH / APP complex system of synergistic flame-retardant effect .
(4) By HDT and Tg testing studied plastic flame retardant type and content on the thermal performance. The results show that, HDT and Tg curve consistent trends, DEEP join will reduce the HDT and Tg.
(5) by means of tensile and flexural properties of the test to study the flame retardant type and content on the mechanical properties of materials. The results showed that three kinds of flame retardants added strength of the material will damage, DEEP join will reduce the material modulus, improve material should
Change, while the ATH and APP modulus and strain on the impact of the DEEP opposite.

Antimony flame retardants
Antimony prices high, heavy smoke, and antimony trioxide is halogen flame retardant synergist essential, therefore trioxide particle fineness requirement is getting smaller, not only can greatly reduce the amount of increase resistance flammable, but also greatly reduce the amount of smoke. Fine now

Magnesium hydroxide and aluminum hydroxide flame retardant disadvantages
Magnesium when heated (340-490 degrees) decompose the surface absorption burning calories play a flame retardant; while releasing large amounts of water dilute combustible surface oxygen, decomposition of the active magnesium oxide attached to combustible surface is further prevents burning for
. magnesium hydroxide flame retardant in the whole process not only does not produce any harmful substances, and its decomposition products in a fire, while also able to absorb a lot of rubber, plastics and other polymer produced by combustion of harmful gases and smoke, constantly absorbing active magnesium oxide incomplete combustion
Burning melting residues from the combustion stop soon while eliminating smoke, preventing droplet, is an emerging environmentally friendly inorganic flame retardants.
Aluminum hydroxide (Aluminium hydroxide), chemical formula Al (OH) 3, of aluminum hydroxide. Is an alkali, but also significant because certain acidic, so can be called aluminate (H3AlO3), but the actual generated by the reaction with alkali aluminate is a partial, it is often
In seeing it as a partial hydrate aluminum acid (HAlO2 · H2O). Use is divided into two kinds of industrial grade and pharmaceutical grade. Very little to do with this flame.

Magnesium hydroxide
Retardant mechanism
Magnesium when heated (340-490 degrees) decomposes to absorb the combustion flame retardant surface heat; while releasing large amounts of water dilute combustible surface oxygen, decomposition of the active magnesium oxide attached to combustible surfaces to prevent further the burning proceed.
Magnesium hydroxide flame retardant in the whole process not only does not produce any harmful substances, and its decomposition products in a fire, while also able to absorb a lot of rubber, plastics and other polymer produced by combustion of harmful gases and smoke, constantly absorbing active magnesium oxide unburned

Classification
Flame retardants can be classified according to the chemical composition of organic and inorganic flame retardants two categories. Organic phosphorus flame retardants are divided into two series, and halogen. Since the existence of organic flame retardants toxic decomposition products, smoke and other shortcomings, are gradually being replaced by inorganic flame retardants. No

Super peel strength.
2, particle size distribution, good compatibility with the substrate, little effect on the mechanical properties of products.
3, dehydration of magnesium hydroxide generated after combustion of magnesium is a high strength, high heat resistant material, can be used as a protective wall, separated from fire, toxic gases, magnesium hydroxide with an acid neutralizing capacity, and can be quickly and plastics in acid gases generated during combustion
SO2, NOx, CO2, etc.
4, magnesium hydroxide decompose high capacity, high efficiency, flame retardant, smoke suppression ability, low hardness, low friction of the equipment that helps extend equipment life.
5, low prices, aluminum hydroxide, magnesium hydroxide is half the price, filling capacity, can greatly reduce the cost of the product.

Flammability
Substances or materials have been treated with a flame spread properties significantly delayed. This range of choice in the use of materials serve as a guide, especially for building materials, ships, vehicles, home appliances and material requirements on high flame retardancy. Currently flame retardancy was evaluated in many ways, such as plastic flame retardant
Oxygen index, horizontal or vertical burning test method.

Scientific understanding of the proper use of the industry called plasticizers
For Taiwan, "plasticizer incident" caused an uproar, September 1, China Petroleum and Chemical Industry Association in Beijing hosted the National plasticizer industry work conference, proposed to scientific understanding of the plasticizer, the plasticizer industry norms development of downstream industries, strict supervision and reasonable use of plasticizers. Plasticizer industry called on the government departments to strengthen planning and management, increase policy and financial support to promote the upgrading of industrial structure plasticizers to meet the needs of the development of related industries.
Plasticizer (Taiwan called plasticizers) in the plastics, rubber processing products indispensable. At present, China has become the world's largest plasticizer production, importing and consuming countries. National plasticizer production capacity has exceeded 400 million tons, accounting for over 50% of the global total capacity, including phthalate plasticizer capacity accounted for 80% or more, and such plasticizers due to benzene, harmful to human health has been under strict international control. Annual consumption of plasticizer is 250 million tons, of which high-end varieties heavily dependent on imports, the annual import volume of nearly 30 million tons, according to People's Daily news, Weihai, Shandong Polymer Materials Co., Ltd. Shandong million figure has been successfully developed to produce Zero environmental toxic benzene safe plasticizer to achieve without the use of imported nationals would allow the possibility of completely non-toxic plasticizer, and the price is high relative to the micro-toxic plasticizer products is much lower.
