Abstract

The invention discloses alkyd paint with excellent yellowing resistance and a preparation method of the alkyd paint. The alkyd paint is prepared from the following components in percentage by mass: 55-65% of alkyd resins, 1-5% of pigments, 1-3% of fillers, 0.5-1.5% of aids, 0.5-1.5% of a catalyst, 0.05-0.25% of a wetting agent, 0.05-0.25% of an anti-skining agent, 1.5-3.5% of antioxidant and 25-35% of a solvent. The preparation method comprises the following steps: adding alkyd resins into a mixer, stirring, adding aids, pigments, an antioxidant and fillers, stirring for 20-30 minutes, adding one of the solvents so as to obtain a mixture; adding the mixture into a grinding machine for grinding; adding a dryer, the wetting agent and the anti-skining agent into the ground mixture, stirring for 20-30 minutes, adding the residual solvents for adjusting the viscosity, stirring for 20-30 minutes, and packaging after detection qualification, so as to obtain the product. The alkyd paint disclosed by the invention has the advantages of high yellowing resistance, excellent overall performance and the like.

Description

technical field [0001] The invention relates to the technical field of alkyd paint processing, in particular to an alkyd paint with good yellowing resistance and a preparation method thereof. Background technique [0002] Alkyd paint, also known as alkyd resin paint or alkyd resin paint, is mainly composed of alkyd resin. It is the largest type of paint in China at present. It has the advantages of cheap price, simple construction, low requirements on the construction environment, and full coating film. It has the advantages of hardness, good durability and weather resistance, good decoration and protection. [0003] Alkyd resin is a kind of polymer prepared by polycondensation reaction with polyol, polybasic acid and fatty acid as the main raw materials. Due to the mature synthesis technology, easy availability of raw materials, and good comprehensive performance of resin coating film, alkyd resin has become a synthetic One of the varieties with the largest amount and wide...
