Abstract

The invention discloses an urushiol boron resin and a preparation method thereof. The urushiol boron resin comprises the following raw materials in percentage by mass: 20-40% of urushiol, 4-8% of aldehyde compound, 0.5-1% of boron compound, 10-20% of epoxy resin, 0.5-1% of catalyst and 40-60% of thinner. The urushiol boron resin has the characteristics of high temperature resistance, alkali resistance, water resistance, oil resistance, wear resistance and strong adhesive force, and can be directly coated on an object. The varnish film has the advantages of excellent heat resistance, water resistance and strong chemical resistance. The product of the invention is suitable for aerospace, electronic information, automobile industry, household appliances and the like.

Description

technical field [0001] The invention relates to an urushiol-based coating, in particular to an urushiol-boron resin and a preparation method thereof, which are mainly used in aerospace, electronic information, automobile industry, household appliances, military industry, petrochemical industry and the like. Background technique [0002] Raw lacquer is a special product in my country, with a history of 8,000 years of use. Raw lacquer film has excellent performance, but the construction conditions and construction technology requirements are relatively high. In order to further develop the use value of lacquer, carry forward the quintessence of the country, meet the requirements of social development, and keep pace with the times. Therefore, many people have modified it, including urushiol epoxy resin, urushiol metal chelate, and formed some achievements, but for the preparation of urushiol borate, currently reported in the literature has Lin Jinhuo and others using urushiol ...
