preparation example Construction

[0015] figure 1 It is a process step chart of the preparation method of high-performance acrylic amino baking varnish in the embodiment of the present invention; the raw material components contained in the acrylic amino baking varnish include: acrylic resin, 582-2 amino resin, medium chrome yellow, titanium dioxide, iron oxide red, phthalocyanine Blue, carbon black, Deqian 5500 defoamer, BYK-163 dispersant, BYK-300 silicone leveling agent, dibutyl phthalate plasticizer, the preparation method includes the following steps: a) preparing Raw materials for acrylic resin preparation, b) Synthetic acrylic resin, c) Grinding and dispersing to prepare paint.

[0016] The high-performance acrylic amino baking varnish mentioned in the present invention uses self-made acrylic resin as the main base material, and is prepared by adding various pigments and fillers, amino resin cross-linking agents with reasonable proportions and other suitable coating additives. Acrylic amino baking varn...

Embodiment

[0018] The specific preparation method is as follows:

[0019] a) Prepare raw materials for acrylic resin preparation, the specific preparation process is: first weigh 22% of xylene, 8% of ethylene glycol butyl ether, 14% of butanol, 28% of styrene, 17.5% of Butyl acrylate, 5.5% of β-hydroxypropyl acrylate, 1% of dibenzoyl peroxide, 1.5% of acrylic acid, 2.5% of methyl methacrylate; then styrene, butyl acrylate, acrylic acid- Mix β-hydroxypropyl ester, acrylic acid, methyl methacrylate and 2 / 3 dibenzoyl peroxide initiator evenly to make component A; then mix 1 / 5 xylene, 1 / 5 ethylene di Alcohol butyl ether and 1 / 3 of dibenzoyl peroxide initiator are mixed evenly to make component B.

[0020] b) Synthesize acrylic resin, the specific preparation process is: first put 4 / 5 xylene, 4 / 5 ethylene glycol butyl ether and all butanol into a heating container equipped with a stirring device and mix evenly, and heat up to 80°C ; Then add component A prepared in step a) dropwise, and kee...

Abstract

The invention provides a high-performance acrylic amino baking varnish and a preparation method thereof. The high-performance acrylic amino baking varnish is prepared from an acrylic resin, a 582-2 amino resin, medium chrome yellow, titanium white, iron oxide red, phthalocyanine blue, carbon black, a Deuchem 5500 defoaming agent, a BYK-163 dispersing agent, a BYK-300 organosilicon leveling agent and a dibutyl phthalate plasticizer. The preparation method comprises the following steps: a) preparing acrylic resin preparation raw materials; b) synthesizing the acrylic resin; and c) grinding and dispersing to obtain the varnish. The acrylic amino baking varnish has the advantages of excellent water resistance, solvent wiping resistance and impact resistance, and can satisfy the high-standard performance requirements of special fields for the paint film.

Description

technical field [0001] The invention relates to a coating, in particular to a high-performance acrylic amino baking varnish and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] Coatings are applied on the surface of objects by different construction techniques to form a continuous solid film with strong adhesion and certain strength. Coatings generally contain four basic components: film-forming substances, pigments, solvents and additives. As a class of modern multifunctional engineering materials, coatings are widely used. At present, my country's coatings industry is developing in three directions: environmental protection, economy, and high performance. It is vigorously developing low-content solvent, water-based and solvent-free, powder, and UV-curable coatings. In recent years, my country's coating industry has been committed to the development of low pollution, high solids or solvent-free coatings, water-based...
