Problems solved by technology

The disadvantage of this alloy material is that due to the use of bromine-containing flame retardants, the plastic parts produced by this alloy material will produce toxic and irritating hydrogen bromide gas during the combustion process, which is likely to cause secondary disasters (that is, cause Victims suffocate, coma or even die), such bromine-containing alloy flame retardant materials have been banned by many countries

Embodiment 1）

[0019] The halogen-free flame-retardant ABS / PA6 alloy material in this embodiment is in granular form. The granular halogen-free flame-retardant ABS / PA6 alloy material is a blending system composed of a plastic alloy of ABS resin and PA6 resin formed by blending and additives blended in the plastic alloy. The additives include flame retardants, compatible toughening agents, lubricating dispersants and antioxidants. There are three kinds of above-mentioned flame retardants, the first flame retardant is melamine cyanurate, the second flame retardant is phosphate, the third flame retardant is sulfonate, the three flame retardants are blended A halogen-free composite flame retardant system is formed in the system.

[0020] The second above-mentioned flame retardant phosphate is melamine pyrophosphate; the third flame retardant sulfonate is potassium 3-benzenesulfonylbenzenesulfonate; the compatible toughening agent is styrene-butadiene-matrix Toic anhydride multi-polymer; Lubric...

Embodiment 2）

[0034] The rest of this embodiment is the same as that of Embodiment 1, except that: in 100kg of halogen-free flame-retardant ABS / PA6 alloy material, each component and corresponding content are as follows:

[0035] ABS resin 50kg, PA6 resin 24kg, the first flame retardant melamine cyanurate 7.952kg, the second flame retardant melamine pyrophosphate 7.952kg, the third flame retardant powder perfluorobutyl sulfonic acid Potassium 0.096kg, compatible toughening agent 8kg, lubricating dispersant 1.5kg, antioxidant 0.5kg.

[0036] The weight ratio of the above three powdered flame retardants is 49.7:49.7:0.6. The third flame retardant powdered potassium perfluorobutane sulfonate comes from Weifang Yucheng Chemical Co., Ltd.

[0037] Correspondingly, when preparing the above-mentioned halogen-free flame-retardant ABS / PA6 alloy material, in step ①, the ABS resin weighed after drying is 50 kg, and the PA6 resin weighed is 24 kg.

[0038] In step ②, the weight of the various raw mat...

Embodiment 3）

[0040] The rest of this embodiment is the same as that of Embodiment 1, except that: in 100kg of halogen-free flame-retardant ABS / PA6 alloy material, each component and corresponding content are as follows:

[0041] ABS resin 52kg, PA6 resin 21kg The first flame retardant melamine cyanurate 7.485kg, the second flame retardant melamine polyphosphate 7.485kg, the third flame retardant 3-benzenesulfonylbenzenesulfonate potassium 0.03 kg, compatible toughening agent 10kg lubricating dispersant 1.5kg antioxidant 0.5kg.

[0042] The weight ratio of the above three powdered flame retardants is 49.9:49.9:0.2. The second flame retardant, melamine polyphosphate, comes from Shanghai Meilaipo Chemical Material Technology Co., Ltd.

[0043] Correspondingly, when preparing the above-mentioned halogen-free flame-retardant ABS / PA6 alloy material, in step ①, the ABS resin weighed after drying is 52 kg, and the PA6 resin weighed is 21 kg.

[0044] In step ②, the weight of the various raw mate...

Abstract

The invention discloses a halogen-free flame-retardant ABS / PA6 alloy material and a preparation method thereof. The alloy material is a blended system consisting of a plastic alloy which is formed by blending ABS resin and PA6 resin and additives which are blended in the plastic alloy, wherein the additives comprise flame retardants, a compatible flexibilizer, a lubricating dispersant and an antioxidant; the flame retardants are melamine cyanurate, phosphate and sulfonate; and the alloy material comprises the following components in part by weight: 50 to 80 parts of ABS resin, 20 to 50 parts of PA6 resin, 5 to 25 parts of three flame retardants in total, 5 to 20 parts of compatible flexibilizer, 0.5 to 2.0 parts of lubricating dispersant, and 0.1 to 0.6 part of antioxidant. The alloy material in the invention does not contain any halogen and is harmless to environment; and the plastic alloy cannot be darkened and keeps the original color, so that the application field of the alloy plastic cannot be limited.

Description

technical field [0001] The invention relates to a polymer composite material and a preparation method thereof, in particular to a halogen-free flame-retardant ABS / PA6 alloy material and a preparation method thereof. Background technique [0002] my country is the world's largest consumer of ABS resin, and its current annual consumption is close to the sum of the United States and Japan. Products are mainly concentrated in electronics and electrical accessories. Among them, refrigerators, TV sets, telephones, modern office supplies and other small household appliances account for about 80% of the total consumption of ABS resin, while toys and auto parts each account for about 10% of the total consumption of ABS resin. ABS resin itself is a flammable and combustible material with an oxygen index of 18.8% to 20.2%. When burning, it has a high heat release rate, a large calorific value, a fast flame propagation speed, and is not easy to extinguish. Sometimes it also produces th...
