Abstract

The invention discloses a solid epoxy plastic board, and materials include epoxy resin, di-n-butyl phthalate, bulking agent, curing agent and foamicide. The invention also discloses a production method of the solid epoxy plastic board, the working environment temperature is 15 to 20 DEG C, and the relative humidity is fifty to sixty percent. In the processing method, one-time release agent is evenly coated inside the mould cavity of a forming mould which is used after fifteen minutes of drying; the epoxy resin and the di-n-butyl phthalate are added into one container, after uniform stirring, the bulking agent is added, when the uniform stirring is continued until no particles exist, the curing agent and the foamicide are added into the container, and the compound is uniformly stired; the compound is poured into the mould cavity of the forming mould, and after solidification lasts eight hours, the board is released; the released board is kept under a constant temperature of 65 DEG C for three hours. The plastic board of the invention has the advantages of good tenacity, high wearability, easy processing, compact structure, long lifespan and low cost.

Description

technical field [0001] The invention relates to a plastic plate and a production method, in particular to a solid epoxy plastic plate suitable for the automobile industry and a production method. Background technique [0002] In the automobile industry, no matter it is the inspection model of sheet metal parts or plastic parts and assembly assemblies, except for a few aluminum alloys, most of them use paste wood substitute resin as the work surface. Shape substitute wood resin is based on epoxy resin synthetic material, the weakness of existing pasty wood substitute resin is: tissue structure is soft, wear resistance is poor, brittleness is big, life-span is short. [0003] With the development of production technology, people began to study new materials, and gradually replaced another new material of paste-like wood substitute resin—polyurethane plastic sheet, which has excellent performance: good toughness, high wear resistance, easy The processing and dense structure ha...
