Embodiment 1

[0008] In this embodiment, a plastic with high heat resistance is composed of the following components according to weight ratio: 80 parts of thermosetting acrylic resin, 17 parts of polypropylene, 40 parts of epoxy resin, 13 parts of sodium tripolyphosphate, stearic acid 15 parts of zinc and 12 parts of talcum powder. At 50°C, put various components into the reaction container for preparation, heat to 120°C for 5 hours while stirring, and obtain high heat-resistant plastic after cooling.

Embodiment 2

[0010] In this embodiment, a plastic with high heat resistance is composed of the following components according to the weight ratio: It is composed of the following components according to the weight ratio: 90 parts of thermosetting acrylic resin, 27 parts of polypropylene, 45 parts of epoxy resin, terpolymer 5 parts of sodium phosphate, 20 parts of zinc stearate and 18 parts of talcum powder. At 50°C, put various components into the reaction container for preparation, heat to 120°C for 5 hours while stirring, and obtain high heat-resistant plastic after cooling.

Embodiment 3

[0012] In this embodiment, a plastic with high heat resistance is composed of the following components according to the weight ratio: It is composed of the following components according to the weight ratio: 86 parts of thermosetting acrylic resin, 21 parts of polypropylene, 43 parts of epoxy resin, terpolymer 9 parts of sodium phosphate, 16 parts of zinc stearate and 17 parts of talcum powder. At 50°C, put various components into the reaction container for preparation, heat to 120°C for 5 hours while stirring, and obtain high heat-resistant plastic after cooling.

Abstract

The invention relates to a plastic with high heat resistance. The plastic is prepared from the following components in parts by weight: 80-90 parts of thermosetting acrylic resin, 17-27 parts of polypropylene, 40-45 parts of epoxy resin, 5-13 parts of sodium tripolyphosphate, 15-20 parts of zinc stearate and 12-18 parts of talcum powder. The plastic disclosed by the invention is reasonable in formula, relatively low in cost and good in heat resistance, and can keep good performances under the high-temperature conditions. Proved by experiments, the plastic can be operated for a long time at 380-400 DEG C; the short-term working temperature can reach 450-500 DEG C.

Description

technical field [0001] The invention relates to a plastic with high heat resistance, which belongs to the field of plastic materials. Background technique [0002] Plastics are widely used and are indispensable components in home appliances, automobiles, mobile phones, PCs, medical devices, and lighting appliances. In recent years, my country's economy has achieved sustained and stable growth. Industries such as home appliances, automobiles, mobile phones, PCs, and medical devices have benefited from a favorable external environment and have also achieved rapid development. The development of downstream industries has further stimulated the demand for plastics. In the application of plastics, people pay more and more attention to the performance of plastics. [0003] Thermosetting acrylic resin is based on acrylic monomers (methyl acrylate, ethyl acrylate, n-butyl acrylate, methyl methacrylate and n-butyl methacrylate, etc.), which are insoluble and insoluble in a network s...
