Abstract

The invention relates to a production method of triethylamine method cold core box resin suitable for high humidity environment, and specially relates to a production method of triethylamine method cold core box resin for casting; the method is as follows: first, synthesizing separately a component I and a component II, and then mixing the components I and the component II; the components I comprises the following raw materials by weight: 42%-65% of benzylic ether phenolic resin, 16.2%-25% of an aromatic solvent, 6%-12% of a citrate plasticizer, 12%-24% of a fatty acid dibasic acid ester plasticizer and 0.4%-0.8% of a silane coupling agent; the components II comprises the following raw materials by weight: 72.5% of polyaryl polymethylene isocyanate (PAPI), 27% of synthetic plant ester and 0.5% of a phosphate ester inhibitor. The method is unique, good in moisture resistant performance and high in environmental protection performance, can improve casting production conditions, achieves ''green casting'', and improves the surface quality and dimension accuracy of castings.

Description

technical field [0001] The invention relates to a production method of a triethylamine method cold box resin suitable for a high-humidity environment, in particular to a production method of a triethylamine method cold box resin for casting. Background technique [0002] The triethylamine cold box process is the most widely used cold box core making process in foundry production. After nearly 20 years of promotion, it has also been widely used in our country. With the development of high-precision technology and green production in foundry enterprises, defects such as poor moisture resistance, poor high-temperature performance, and low environmental protection performance exposed by the cold box molding process have hindered modern foundry enterprises from moving toward refinement and "green casting" direction of development. [0003] There is currently no method for overcoming the aforementioned drawbacks. Contents of the invention [0004] The purpose of the present i...
