SMC (Sheet Molding Compound) composite sheet for hog house slatted plate and preparation method of SMC composite sheet

Abstract

The invention relates to the technical field of composite materials, in particular to an SMC composite sheet for a pigsty slatted plate and a preparation method of the SMC composite sheet. The SMC composite sheet for the hog house slatted plate is prepared from the following raw material components in parts by weight: 25 to 30 parts of orthophthalic unsaturated polyester resin, 3 to 5 parts of styrene, 6 to 10 parts of transparent benzene, 0.1 to 0.5 part of tert-butyl peroxybenzoate, 0.005 to 0.02 part of p-benzoquinone, 10 to 20 parts of glass fiber, 5 to 10 parts of heat-conducting particles, 7 to 14 parts of heat-conducting fiber, 5 to 10 parts of filling agent, 10 to 20 parts of thickening agent and 1 to 5 parts of release agent. Wherein the heat-conducting particles are prepared by coating modified nanometer aluminum oxide with polyethylene glycol, and the heat-conducting fibers are carbon fibers. The polyethylene glycol coated modified nano aluminum oxide heat-conducting particles and the graphene carbon fibers are added into the SMC composite sheet to form a heat-conducting channel, so that the prepared SMC composite sheet has relatively good mechanical strength and heat-conducting property.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a SMC composite sheet used for slats in a pig house and a preparation method thereof. Background technique [0002] At present, the cement slats are mainly used in the industry. The cement slats have excessive weight, high production costs, high hoisting costs, and extremely inconvenient installation in high-rise pig farms; SMC, also known as sheet molding compound, is made of polymer A type of sheet molding compound made of ester resin paste impregnated glass fiber, with good strength and toughness, light weight, convenient installation, and can be used for the installation of high-rise pig farms. [0003] Under the intensive production mode of the existing pig farms, the breeding density of pigs is relatively high, and the temperature in the southern region is long in summer. In view of the above-mentioned defects of the prior art, it is necessary to provide a SMC ...

AI Technical Summary

Problems solved by technology

[0002] At present, the cement slatted board is mainly used in the fat pig board in the industry. The weight of the cement slatted board is too large, the production cost is high, the hoisting cost is high, and the installation of high-rise pig farms is extremely inconvenient; SMC is also called sheet molding compound. A type of sheet molding material made of ester resin paste impregnated with glass fiber. It has good strength and toughness and is light in weight. It is easy to install and can be used for installation in high-rise pig farms.

[0003] Under the intensive production mode of existing pig farms, the breeding density of pigs is high, and the summer time in the southern region is long and the temperature is high. The poor thermal conductivity of ordinary SMC sheets is not conducive to the release of pig body surface temperature and easily leads to animal heat stress. For the above-mentioned defects of the prior art, it is necessary to provide a SMC composite sheet with strong thermal conductivity for the preparation of slats for piggery
