Embodiment 1

[0019] Prepare 17% epoxy resin, 50% acetone, 25.5% calcium carbonate powder, 4% by weight of resorcinol, 3.5% by weight of aminoethylpiperazine, mix epoxy resin and Dissolve resorcinol, then add calcium carbonate powder, add aminoethylpiperazine before use, after stirring evenly, a resin protection layer 2 is formed, and finally coated on the mold body 1.

Embodiment 2

[0021] Prepare 25% epoxy resin, 40% acetone, 30% calcium carbonate powder, 2.5% by weight of resorcinol, 2.5% by weight of aminoethylpiperazine, mix epoxy resin and Dissolve resorcinol, then add calcium carbonate powder, add aminoethylpiperazine before use, after stirring evenly, a resin protection layer 2 is formed, and finally wrapped on the mold body 1.

[0022] In the composite material mold provided by the present invention, the outer surface of the mold body has at least one layer of resin protective layer, which is coated or wrapped on the outer surface of the rod body, so that the surface of the mold is smoother, the product quality is obviously improved, and the mechanical strength of the mold is improved. Wear-resistant and corrosion-resistant performance, long service life, simple manufacturing method, low cost, can be widely used.

Abstract

The invention relates to a composite material mould, comprising a mould body, wherein the outer surface of the mould body is provided with at least one composite material layer which is a resin protective layer.The composite material mould has the advantages of improved mechanical strength, abrasive resistance, decay resistance and long service life. In addition, the working surface of the mould retains the original excellent water absorption property; and moreover, the mould is simple in manufacturing method, low in cost and wide in applicability.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a mold coated or wrapped with composite materials. Background technique [0002] The so-called molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, casting, forming, smelting, stamping, stretching and other methods to obtain the required products. In short, a mold is a tool used to shape an item. The level of mold technology is an important symbol to measure the level of manufacturing industry. [0003] In the known technology, in the ceramic industry, gypsum molds are usually used to form ceramics. This gypsum mold has excellent water absorption performance, but its mechanical strength is low, and its wear resistance and corrosion resistance are poor, which seriously affects the service life of the mould. Contents of the invention [0004] In view of the above defects, the purpose of the present invention is to provide...
