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 derivative modified unsaturated polyester resin compositions of a kind of tung oil and preparation method thereof.
Background technology
Unsaturated polyester resin (Unsaturated Polyester Resin, UPR) is thermosetting resin, is generally formed, had the chain macromolecule compound of ester bond and unsaturated double-bond by unsaturated dibasic acid and dibasic alcohol polycondensation.Its production technique is simple, raw material is easy to get, and over-all properties is good, has high rigidity, high fullness ratio, and weathering resistance, water tolerance, oil-proofness 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 while adopting universal UPR to prepare coating, exist air-drying property bad, the shortcoming such as sticking power, snappiness and shock resistance are poor.Along with the continuous expansion of production field and the enhancing day by day of people's environmental consciousness, common UPR cannot adapt to the demand of social development.
At present improve for the study on the modification of unsaturated polyester resin the problem existing when unsaturated polyester is prepared coating, mainly carry out modification with urethane or base polyurethane prepolymer for use as, acrylic resin, organosilicon, nano material and vegetables oil.Wherein, crude vegetal has wide material sources, various in style, cheap, alternative strong, degradable and the plurality of advantages such as renewable, so plant oil modified unsaturated polyester resin is more and more subject to people and payes attention to.
In vegetables oil, adopt soybean oil, oleum lini, Viscotrol C, Semen Maydis oil, tung oil also to have report by the method for chemosynthesis modified unsaturated polyester resin.The method is in unsaturated polyester resin building-up process, to add a certain amount of above-mentioned vegetables oil, its long reaction time, complex operation, and temperature of reaction is high, easily cause that the polymerization between two keys and two key occurs vegetables oil self, thereby do not reach the desired result of modification, affect quality product.At present, there is not yet bibliographical information with the method for the derivative blended modified unsaturated polyester resin composition of tung oil.
Summary of the invention
Technical problem solved by the invention is to provide derivative modified unsaturated polyester resin compositions of a kind of tung oil and preparation method thereof, to solve the shortcoming in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
The derivative modified unsaturated polyester resin compositions of tung oil, its moiety and content ratio are as follows:
Unsaturated polyester resin: 100 g;
Tung oil derivative: 1～12 g;
Antioxidant: 0.3～0.5 g;
Thermo-stabilizer: 0.3～0.8 g;
Photostabilizer: 0.3～1.5 g;
Mould inhibitor: 0.3～0.6 g;
Defoamer: 0.2～0.5 g.
In the present invention, described tung oil derivative is one or more in eleostearic acid, methyl eleostearate (ME), epoxidation methyl eleostearate (EME), eleostearic acid mono-glycerides (EAM), paulownia horse adducts (MEMAA) and tung oil polylol (TOAEP).
In the present invention, described antioxidant is antioxidant 1010; Described thermo-stabilizer is Zinic stearas; Described photostabilizer is 2-hydroxyl-4-dodecyl-benzophenone; Described mould inhibitor is copper 8-quinolinolate; Described defoamer is JF-1102 silicone antifoam agent.
The preparation method of the derivative modified unsaturated polyester resin compositions of tung oil based on above-mentioned composition and content, idiographic flow is: in reaction vessel, add unsaturated polyester resin and tung oil derivative, stir, add successively antioxidant, thermo-stabilizer, photostabilizer, mould inhibitor, defoamer, after being uniformly mixed, make the derivative modified unsaturated polyester resin compositions of thermohardening type tung oil simultaneously.
beneficial effect:
The feature such as the fast drying, strong adhesion, snappiness and the impact resistance that utilize tung oil derivative to have in the present invention are good, utilize the consistency that tung oil derivative and unsaturated polyester resin are good to carry out modification to unsaturated polyester resin, thereby improve and increase the over-all properties after unsaturated polyester resin solidifies, can obtain a kind of air-drying property good, the unsaturated polyester resin coating that strong adhesion, snappiness and shock resistance are good.The derivative modified unsaturated polyester resin compositions of tung oil has the features such as good operate continuously, fast setting and high adhesive force, can be used as heat curing coating and is applied to the fields such as building, automobile and chemical industry.
