Embodiment 1

[0009] In this embodiment, a high-temperature-resistant, acid- and alkali-resistant plastic is composed of the following components according to weight ratio: 32 parts of acrylonitrile, 35 parts of butadiene, 32 parts of styrene, 20 parts of epoxy resin, 18 parts of polytetrafluoroethylene 23 parts and talcum powder. At 120°C, put various ingredients into the reaction vessel for preparation, stir evenly, keep for 6 hours, put it in the mold of the die-casting machine and die-cast it to obtain a plastic with high temperature resistance, acid and alkali resistance.

[0010] The flame retardancy of the plastic was tested using the UL94 standard, and the results showed that the flame retardancy of the plastic in this embodiment could reach the V-0 level. In addition, the plastics of this example were immersed in 2 mol / L sodium hydroxide solution and 2 mol / L phosphoric acid solution for 18 days, without any abnormal phenomenon, and had good acid and alkali resistance.

Embodiment 2

[0012] In this embodiment, a high-temperature, acid- and alkali-resistant plastic is composed of the following components according to weight ratio: 40 parts of acrylonitrile, 25 parts of butadiene, 40 parts of styrene, 15 parts of epoxy resin, 28 parts of polytetrafluoroethylene 30 parts and talcum powder. At 120°C, put various ingredients into the reaction vessel for preparation, stir evenly, keep for 6 hours, put it in the mold of the die-casting machine and die-cast it to obtain a plastic with high temperature resistance, acid and alkali resistance.

[0013] The flame retardancy of the plastic was tested using the UL94 standard, and the results showed that the flame retardancy of the plastic in this embodiment could reach the V-0 level. In addition, the plastics of this example were soaked in 2mol / L sodium hydroxide solution and 2mol / L phosphoric acid solution for 19 days, without any abnormal phenomenon, and had good acid and alkali resistance.

Embodiment 3

[0015] In this embodiment, a high-temperature, acid- and alkali-resistant plastic is composed of the following components according to weight ratio: 36 parts of acrylonitrile, 31 parts of butadiene, 36 parts of styrene, 19 parts of epoxy resin, 22 parts of polytetrafluoroethylene 26 parts and talcum powder. At 120°C, put various ingredients into the reaction vessel for preparation, stir evenly, keep for 6 hours, put it in the mold of the die-casting machine and die-cast it to obtain a plastic with high temperature resistance, acid and alkali resistance.

[0016] The flame retardancy of the plastic was tested using the UL94 standard, and the results showed that the flame retardancy of the plastic in this embodiment could reach the V-0 level. In addition, the plastic of the present invention is immersed in 2 mol / L sodium hydroxide solution and 2 mol / L phosphoric acid solution for 20 days, without any abnormal phenomenon, and has good acid and alkali resistance.

Abstract

The invention discloses high-temperature-resistant and acid-and-base-resistant plastic. The plastic comprises the following active ingredients in parts by weight: 32-40 parts of acrylonitrile, 25-35 parts of butadiene, 32-40 parts of styrene, 15-20 parts of epoxy resin, 18-28 parts of polytetrafluoroethylene, and 23-30 parts of talcum powder. The plastic is subjected to flame retardance and acid and base resistance experiments. The flame retardance of the plastic is tested by adopting UL94 standard, the result shows that the flame retardance effect of the plastic can achieve V-0 grade, and the plastic has an excellent effect. In addition, the plastic has no any abnormal phenomenon after being respectively soaked in 2mol / L sodium hydroxide solution and 2mol / L phosphoric acid solution for 18-20 days, thus having excellent acid and base resistance property.

Description

technical field [0001] The invention relates to a high-temperature-resistant, acid-alkali-resistant plastic, which belongs to the field of plastic materials. Background technique [0002] Plastic products can be used in many ways, such as motorcycle pedals, electronic products, track and so on. In the application of plastics, people pay more and more attention to the performance of plastics. However, most plastics are flammable due to the addition of plasticizers, etc., and melt at a slightly higher temperature, thus greatly reducing the safety of plastics. As plastics are used in construction, furniture, transportation, aviation, aerospace, With the wide application of electrical appliances and other aspects, improving the high temperature resistance of plastics has become a very urgent issue. In addition, most plastics have poor acid resistance and cannot adapt to some special requirements. [0003] Therefore, a high-temperature-resistant, acid- and alkali-resistant pla...
