Abstract

The invention discloses a production process of a high-wear-resistance glass fiber reinforced plastic pipe, and belongs to the technical field of glass fiber reinforced plastic preparation processes. The method comprises the following steps: 1, weighing the following raw materials in parts by weight: 10-30 parts of polyethylene, 15-25 parts of epoxy resin, 5.6-11.6 parts of nano ceramic particles, 6-8 parts of glass fibers, 4-6 parts of a coupling agent, 5-10 parts of cyclohexanone, 5.5-7.5 parts of a corrosion-resistant agent and 12-14 parts of a wear-resistant agent; 2, mixing the raw materials in sequence; 3, adding a wear-resistant agent, and carrying out extrusion molding; and preparing and adding a corrosion-resistant agent, wherein the corrosion-resistant agent has two chloramine structures with antibacterial activity and an antioxidant semi-hindered phenol structure, and the corrosion-resistant agent can effectively reduce corrosion of microorganisms and oxidation on the prepared glass reinforced plastic pipe, so that the structural integrity of the glass reinforced plastic pipe is further maintained, and the wear-resistant function is further improved.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastic preparation technology, in particular to a production technology of high wear-resistant glass steel pipe. Background technique [0002] FRP, that is, fiber reinforced plastics, generally refers to reinforced plastics that use unsaturated polyester resin, epoxy resin and phenolic resin as a matrix, and glass fibers or their products as reinforcement materials, also known as glass fiber reinforced plastics. FRP has the advantages of light and hard, non-conductive, high mechanical strength, less recycling, and corrosion resistance, so it is widely used in various fields in industry. [0003] According to different substrates, FRP can be divided into unsaturated polyester FRP, epoxy FRP, and phenolic FRP. Due to the different types of resin matrix used, there are also great differences in the characteristics of FRP. FRP is often used to make pipes, and the pipes often need to ...
