Abstract
The invention discloses a tung oil derivative-modified unsaturated polyester resin composition and a preparation method thereof. The preparation method comprises the steps: by taking a tung oil derivative and general type unsaturated polyester resin as primary materials, adding a certain amount of an antioxidant, a thermal stabilizer, a light stabilizer, a mildew preventive and a defoaming agent, stirring and mixing uniformly at a normal temperature to prepare the tung oil derivative-modified unsaturated polyester resin composition. After being added with an initiator and an accelerant, the composition is heated for reacting and curing to form a co-mixing structure composite of tung oil derivative monomer and an unsaturated polyester macromolecule, so that problems such as bad air-drying performance, poor adhesion force, poor flexibility, poor impact resistance, and the like, of the existing unsaturated polyester resin paint are solved, and therefore, the tung oil derivative-modified unsaturated polyester resin composition can be used as thermocuring paint for being applied to the fields such as buildings, cars, chemical engineering, and the like. The method has the advantages of being low in production cost, simple and convenient to operate, short in production period, small in environmental pollution, and the like.
Description
Technical field
The present invention relates to the field of chemical synthesis, be specially a kind of derivative modified unsaturated polyester resin compositions of Oleum Verniciae fordii and preparation method thereof.
Background technology
Unsaturated polyester resin (Unsaturated Polyester
Resin, UPR) be thermosetting resin, be usually by unsaturated dibasic acid and dihydroxylic alcohols polycondensation, there is ester bond and the chain macromolecule compound of unsaturated double-bond.Its production technology is simple, raw material is easy to get, and combination property is good, has high rigidity, high richness, and weatherability, resistance to water, oil resistivity are good, and glossiness is high, and electric insulating quality is excellent, and light weight and the advantage such as cheap, be one of important coating film-forming resin.But it is bad to use universal UPR to there is air-drying property when preparing coating, the shortcomings such as adhesive force, pliability and shock resistance are poor.Along with constantly expanding and the enhancing day by day of people's environmental consciousness of production field, common UPR cannot adapt to the demand of social development.
Study on the modification for unsaturated polyester resin improves the problem existed when unsaturated polyester (UP) prepares coating at present, is mainly modified with polyurethane or base polyurethane prepolymer for use as, acrylic resin, organosilicon, nano material and vegetable oil.Wherein, crude vegetal has wide material sources, strong, degradable various in style, cheap, alternative and the plurality of advantages such as renewable, so, plant oil modified unsaturated polyester resin is increasingly paid attention to by people.
In vegetable oil, soybean oil, oleum lini, Oleum Ricini, Semen Maydis oil, Oleum Verniciae fordii is used also to be had been reported that by the method for chemosynthesis modified unsaturated polyester resin.The method is to add a certain amount of above-mentioned vegetable oil in unsaturated polyester resin building-up process, and its response time is long, complex operation, and reaction temperature is high, easily cause vegetable oil self that being polymerized between double bond and double bond occurs, thus do not reach the Expected Results of modification, affect product quality.At present, there is not yet document report with the method for Oleum Verniciae fordii derivative blended modified unsaturated polyester resin compositions.
Summary of the invention
