Abstract


Due to the concerns and needs of the people of environmentally friendly coatings , as well as the release of volatile organic compounds and coating production process waste emissions of human distress , in recent years , the use of resources instead of natural plant oils and partially replace oil-producing chemical products , has been in The coatings industry development . The same time , with the development of the knowledge of organic chemistry and coating Physical Chemistry gradually resolve the problems encountered in the process of development of vegetable oil -based products , such renewable plant resources based formulations paint product performance can be greatly improved and enhanced . Around renewable plant resources in preparation of coatings the effective exploration carried out in the following areas : ( 1 ) to study the new technology of tall oil preparation industry primer with a simple separation process from pulping waste . Paper waste , tall oil , purified by vacuum distillation , appropriate Combined additives , quality alkyd resin , and thereby produce a better performance of the industrial primer . The study found that the mechanical properties and appearance of the primer coating film as determined by the modified alkyds esterization temperature and industrial primer ratio . The petroleum resin modified alkyd resin obtained industrial primer smooth appearance , the table one thousand time 6min, drying time 10h, 24h water resistance test , no change . The results show that , good the industrial primer performance prepared by the new process , the waste separation process is simple , with good economic and environmental benefits . (2 ) selection of rice bran oil , tung oil, epoxy resin , iron oxide red synthetic iron oxide red primer. The study found that the mechanical properties and appearance of the primer coating film is determined by the ratio of the epoxy ester , esterification temperature , and the ratio of iron red primer . Using rice bran oil and tung oil addition reaction , the reaction temperature of 200 ~ 220 ℃ the resulting iron red epoxy primer smooth appearance , coating viscosity
