Abstract

The present invention relates to a fast drying steel casting coating, including by weight: 45-69 parts of graphite, 10-15 parts of kaolin, 4-10 parts of talc powder, 2-5 parts of quartz powder, 1-5 parts of tributyl phosphate, 6-10 parts of polyvinyl alcohol, 36-45 parts of silica gel and 11-15 parts of maleinized tung oil acid ester. The coating of the present invention helps to reduce the cost of materials, also reduce gas evolution, solve the problem of generating choking of casting, and improve the quality of the casting.

Description

technical field [0001] The invention belongs to mechanical casting technology and relates to a quick-drying cast steel. Background technique [0002] In order to reduce the loss of sand molds and cores, save the drying process, and match with various chemical hardening sand molding processes, quick-drying cast iron coatings should be used instead of water-based cast iron coatings. "TK-8210" cast iron quick-drying coating was developed by Shaanxi Institute of Mechanical Engineering and Shaanxi Automobile Manufacturing Factory casting coating development group. It has good process performance. But its suspending ability is poor, only 85%, and the resin content is high, which causes the average gas generation to reach 43.3mL / g. Contents of the invention [0003] The purpose of the present invention is to prepare a fast-drying cast steel coating with high suspending property, low gas generation and the ability to reduce the surface roughness of castings. [0004] A kind of ...
