Abstract

The invention relates to quick-dry type acrylic modified alkyd paint which is characterized by comprising the following components in parts by weight: 35-65 parts of acrylic modified alkyd resin, 15-25 parts of pigment, 10-25 parts of filling, 0.5-2.0 parts of anti-settling agent, 0.3-1.0 part of dispersant, 0.3-0.6 part of flatting agent, 0.3-0.6 part of antifoaming agent, 2-5 parts of drier, 0.1-0.3 part of anti skinning agent, 10-20 parts of heavy aromatic, 10-20 parts of xylene and 5-15 parts of prime city naphtha. The preparation method comprises the following steps of: adding the front four raw materials of the acrylic modified alkyd resin, and the like into a burdening pot; evenly stirring a mixture, dispersing the mixture for 20 minutes at high speed; grinding the mixture in a sand grinder into fineness of 30micron; filling pigment paste into a paint mixing tank; adding the last seven raw materials; evenly stirring; and filtering. The invention has the beneficial effects that various colors of acrylic modified alkyd paint is prepared by using the acrylic modified alkyd resin as a base material; and a paint film is quickly dried, and has the characteristics of good light retention property, weather resistance and recoatability, high decoration performance, and greatly improved comprehensive physical and chemical properties.

Description

technical field [0001] The invention belongs to coatings, in particular to a quick-drying acrylic modified alkyd paint and a preparation method thereof. Background technique [0002] Alkyd paint is a type of paint with alkyd resin as the main film-forming substance. Gloss, flexibility, abrasion resistance, weather resistance and adhesion are good, which can meet the general requirements of use, but the drying speed of alkyd paint is slow (6-8 hours for surface drying), and the hardness is low (0.25), which cannot meet some workpieces Construction requirements of fast drying, high hardness and high weather resistance. In order to modify the existing alkyd resin, many units have done a lot of research work, such as modifying alkyd resin with epoxy resin, acrylic resin, silicone resin, etc., so as to improve its adhesion, weather resistance, and durability respectively. thermal properties. The use of acrylic modified alkyd resin can greatly improve the drying speed (surface ...
