Problems solved by technology

[0003] However, with the development of the automobile and electronics industries, there is an increasing demand for high-temperature-resistant materials. However, generally unsaturated polyester can only reach the temperature-resistant level of Class B, which cannot meet the high-strength requirements required for work in high-temperature environments. , therefore, the development of high temperature resistant unsaturated polyester resin should be the main trend in the future
[0004] In addition, most unsaturated polyester products have flame retardant components that are halogen elements. With the rapid increase in the application of unsaturated polyester products in industrial and agricultural production and daily life, the probability of fire is also greatly increased, and the occurrence of fire will cause serious personal injury.

Embodiment 1

[0020] First, put 70 parts of novolak epoxy vinyl ester resin and 30 parts of polystyrene type low-shrinkage agent into the mixing tank according to the weight fraction ratio, and stir evenly, and add 5 parts of styrene, tert-butyl peroxide in turn under the condition of stirring. 1.0 parts of oxidized-2-ethylhexanoate, 1.5 parts of p-benzoquinone, 5 parts of zinc stearate, 20 parts of triethyl phosphate, stirred for 5 minutes until uniformly mixed, then added 140 parts of calcium carbonate and increased the stirring speed, Disperse at high speed for 10 minutes, then compound with 140 parts of glass fiber, and then cure in a drying room at 40°C for 72 hours at low temperature. Laminate according to the thickness after curing, and cure in a high-temperature mold at a temperature of 130°C for 8 minutes to obtain a halogen-free flame-retardant high-heat-resistant unsaturated polyester glass fiber composite material.

Embodiment 2

[0022] First, put 80 parts of bisphenol A type epoxy vinyl ester resin and 20 parts of polyvinyl acetate type low shrinkage agent into the mixing tank and stir evenly according to the weight fraction ratio, and add 5 parts of styrene, tert- 1.5 parts of butyl peroxy-2-ethylhexanoate, 1.8 parts of p-benzoquinone, 5 parts of zinc stearate, 10 parts of melamine, stirred for 5 minutes until uniformly mixed, then added 120 parts of calcium carbonate and increased the stirring speed, Disperse at high speed for 10 minutes, then compound with 140 parts of glass fiber, and then cure in a drying room at 40°C for 48 hours at low temperature. Laminate according to the thickness after curing, and cure in a high-temperature mold at a temperature of 130°C for 8 minutes to obtain a halogen-free flame-retardant high-heat-resistant unsaturated polyester glass fiber composite material.

Embodiment 3

[0024] First, put 85 parts of isophthalic unsaturated polyester and 15 parts of polyethylene terephthalate low-shrinkage agent into the mixing tank according to the weight fraction ratio, and stir evenly, and add 5 parts of styrene in turn under the condition of stirring , 2 parts of tert-butyl peroxy-2-ethylhexanoate, 3 parts of p-benzoquinone, 5 parts of zinc stearate, 20 parts of triethyl phosphate, stir for 5 minutes until mixed evenly, then add 160 parts of calcium carbonate And increase the stirring speed, disperse at a high speed for 10 minutes, and then compound with 140 parts of glass fibers, and then undergo low-temperature aging at 40°C in a drying room for 24 hours. Laminate according to the thickness after curing, and cure in a high-temperature mold at a temperature of 140°C for 5 minutes to obtain a halogen-free flame-retardant high-heat-resistant unsaturated polyester glass fiber composite material.

Abstract

The invention relates to a halogen-free flame-retardant high-heat-resistant unsaturated polyester glass fiber composite material, which comprises unsaturated polyester resin, low shrinkage agent, crosslinking monomer, initiator, polymerization inhibitor, release agent, halogen-free The flame retardant component and the inorganic filler are mixed uniformly first, then compounded with glass fiber, cured at a certain time and temperature after aging, and a halogen-free flame retardant high heat resistant unsaturated polyester glass fiber composite material is obtained. The method of the invention is simple, and the prepared halogen-free flame-retardant high-heat-resistant unsaturated polyester glass fiber composite material has good comprehensive performance, excellent mechanical properties under normal conditions and high temperatures, and is halogen-free and flame-retardant, meeting environmental protection requirements.

Description

technical field [0001] The invention relates to the field of insulating materials, in particular to an unsaturated polyester glass fiber composite material. Background technique [0002] Unsaturated polyester-based glass fiber (chopped strand, chopped strand mat, continuous mat, etc.) composite material has excellent electrical and mechanical properties, and unsaturated polyester has excellent thermal processing properties compared with epoxy resin , High production efficiency and other characteristics, so the application of unsaturated polyester is becoming more and more extensive. [0003] However, with the development of the automobile and electronics industries, there is an increasing demand for high-temperature-resistant materials. However, generally unsaturated polyester can only reach the temperature-resistant level of Class B, which cannot meet the high-strength requirements required for work in high-temperature environments. Therefore, the development of high tempe...
