Effect test

Embodiment 1

[0010] At 70°C, put the ingredients of Example 1 in Table 1 into the reaction kettle according to the weight, stir evenly, heat to 200°C for 10 hours, and after cooling, a plastic with good flame retardant, acid and alkali resistance can be obtained. The plastic is subjected to a flame retardancy test, the test standard is UL94 standard, and the flame retardancy test result is V-1 level, which has a good flame retardancy effect. In addition, the plastic is kept at a burning temperature of 700°C for 15 hours, and the flame-retardant and heat-resistant plastic containing 3,3-dimethylmethacrylate does not have any abnormal phenomena, and has good flame-retardant and heat-resistant properties.

Embodiment 2

[0012] The plastic preparation method and performance testing method are the same as in Example 1, the difference is that the component content is prepared as in Example 2 shown in Table 1, and the heat resistance is measured at 800°C for 15 hours. The results show that the flame retardant performance test results of the final product are also V-1 level, which has a good flame retardant effect. After being kept at 800°C for 15 hours, no other changes occurred in the plastic, and the original performance and appearance were still maintained.

Embodiment 3

[0014] The plastic preparation method and performance testing method are the same as in Example 1, the difference is that the component content is prepared as in Example 3 shown in Table 1, and the heat resistance is measured at 750° C. for 15 hours. The results show that the flame retardant performance test results of plastics containing 3,3-dimethyl methacrylate are also V-1 level, which has a good flame retardant effect. After being kept at 750°C for 15 hours, no other changes occurred in the texture and appearance of the plastic, and the original performance was retained.

Abstract

The invention relates to methyl 3,3-dimethylacrylate-containing flame-retardant heat-resistant plastic which comprises the following ingredients in parts by weight: 50-60 parts of methyl 3,3-dimethylacrylate, 40-50 parts of cyclobutene, 40-50 parts of polydodecalactam, 10-20 parts of talcum powder, 10-20 parts of ethylene glycol, 10-20 parts of zinc sulfide, and 10-20 parts of propylene. The prepared methyl 3,3-dimethylacrylate-containing plastic is good in flame-retardant and heat-resistant effects.

Description

technical field [0001] The invention relates to a flame-retardant and heat-resistant plastic, in particular to a flame-retardant and heat-resistant plastic containing 3,3-methyl methacrylate. Background technique [0002] With the continuous development of society, the plastic industry has also made great progress. In the process of development, people's demand for plastics is increasing, and the requirements for plastics are also getting higher and higher. In the professional field involving flame-retardant and heat-resistant plastics, customers have increasingly high requirements for flame-retardant and heat-resistant plastics. At present, there are few types of plastics that have both flame-retardant and heat-resistant effects on the market. Plastics with good flame retardancy and heat resistance have very broad market prospects. Contents of the invention [0003] The technical problem to be solved: the problem of poor flame retardancy and heat resistance of conventio...
