Abstract

The invention discloses an alloy material for a plastic valve. The alloy material is characterized by comprising components in parts by mass as follows: butadiene styrene rubber, a tertiary fluoro emulsion, etherified melamine resin, polybutylene terephthalate, coal ash, zirconia ceramic micro powder, boron silicide, cobaltic yttrium glycinemethane dithioate, tetraethylthiuram disulfide, trichloropropylphosphate, carbon fibers, 350-mesh iron powder, an antioxidant and isopropyl tri(dioctylpyrophosphate) titanate. The invention further discloses a preparation method of the alloy material for the plastic valve. A test result show that the prepared alloy material for the plastic valve has higher compression strength and good wear resistance, the preparation process is simple, the cost is low, and the alloy material is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an alloy material for a plastic valve body and a preparation method thereof. Background technique [0002] The valve is a control component in the pipeline fluid delivery system. It is used to change the passage section and the flow direction of the medium, and has the functions of diversion, cut-off, throttling, check, diversion or overflow relief. Valves can be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metal and radioactive fluids. [0003] Nowadays, metal valve bodies are favored due to their safety in use and long service life. However, with the shortage of metal resources, the production cost of metal valve bodies continues to rise. Therefore, more and more alternative plastic valve bodies have appeared. Among the plastic valve bodies, PTFE valve bodies are popular due to their good he...
