Abstract

The invention discloses styrene modified alkyd resin which comprises the following raw materials in percentage by weight: 12-30% of styrene, 8-16% of xylene, 24-35% of trimethylbenzene, 14-19% of soybean oil, 1.5-1.8% of a toughening agent, 1-5% of tung oil, 7-9% of phthalic anhydride, 1-4% of pentaerythritol, 1-3% of epoxy resin, 1-3% of benzoic acid, 1-5% of maleic anhydride, 1.5-2% of grease leftovers, 0.01-0.03% of a catalyst, and 1-3% of an initiator. The invention further discloses alkyd resin paint containing the styrene modified alkyd resin. The alkyd resin paint comprises the following components in percentage by weight: 70-99% of the styrene modified alkyd resin disclosed by the invention, 0-30% of pigment and 0.2-1.5% of an additive. The styrene modified alkyd resin disclosed by the invention is simple in preparation method, due to copolymerization reaction of styrene, unsaturated fatty acid and maleic anhydride, the modified alkyd resin has the characteristics of high hardness and rapid dryness, when the modified alkyd resin is used in alkyd resin paint, the defects that the conventional alkyd resin paint is long in construction period, low in working efficiency and poor in water resistance are overcome.

Description

technical field [0001] The present invention relates to a polymer resin, in particular to a styrene-modified alkyd resin and a preparation method thereof. In addition, the present invention also relates to a styrene-modified alkyd containing the styrene-modified alkyd resin A resin paint belongs to the field of polymer materials. Background technique [0002] Due to the mature synthesis technology of alkyd resin, simple manufacturing process, easy access to synthetic raw materials, etc., and its good gloss, adhesion, wear resistance, insulation and other characteristics after curing into a film, it currently has a large market share. Rate, this method is applied to the fields such as metal protection, furniture, vehicle, construction, in addition, also is used as the insulating layer of enameled wire in a large amount, and is made ink and is used in printing industry in large quantities. However, due to the defects of slow drying, low hardness and poor water resistance of a...
