Problems solved by technology

[0005] However, existing matt coatings still have many disadvantages
For example, commonly used UV low-gloss coatings are often difficult to achieve a better matt effect (such as full matt effect, etc

Embodiment 1

[0057] Embodiment 1: the preparation of coating composition-1

[0058] In this example, PPG Oak Creek's URETHANE ACRYLATE, a low molecular weight highly branched aliphatic urethane acrylate oligomer, was used as the oligomer; and 1,6-hexanediol diacrylate was used as the monomer .

[0059] Components 1 and 2 were mixed together at room temperature in the amounts indicated in the table below, and the mixture was stirred homogeneously using a EUROSTAR mixer from IKA-WERKE at 800 rpm. Slowly add matting powder at 500rpm, then disperse the mixture at 1500rpm for 20 minutes until the fineness reaches 40 microns. Subsequently, long oil alkyd resin (CS-100 of Guolong) was added, and the mixture was stirred uniformly at a rotation speed of 800 rpm, thereby obtaining coating composition-1 according to the present invention, which was a full matte coating.

Embodiment 2

[0062] Embodiment 2: the preparation of coating composition-2

[0063] In this example, PPG Oak Creek's URETHANE ACRYLATE (a low molecular weight highly branched aliphatic urethane acrylate oligomer) and RAHN's GENOMER3414 (a low molecular weight polyether acrylate oligomer) were used as oligomers. and use a mixture of propoxylated neopentyl glycol diacrylate, tetrahydrofurfuryl acrylate, 1,6-hexanediol diacrylate, ethoxylated 1,6-hexanediol diacrylate as mono body.

[0064]Components 1 to 6 in the amounts shown in the table below were mixed together at room temperature, and the mixture was stirred uniformly at 800 rpm using a EUROSTAR mixer from IKA-WERKE. Slowly add matting powder at 500rpm, and disperse the mixture at 1500rpm at high speed for 15-30 minutes until the fineness reaches 35 microns. Subsequently, long oil alkyd resin (CS-100 of Guolong) was added, and the mixture was stirred evenly at a rotation speed of 800 rpm, thereby obtaining coating composition-2 accord...

Embodiment 3

[0067] Embodiment 3: the preparation of coating composition-3

[0068] In this example, PPG Oak Creek's URETHANE ACRYLATE and RAHN's GENOMER 3414 were used as oligomers; and propoxylated neopentyl glycol diacrylate, tetrahydrofurfuryl acrylate, 1,6-hexanedi A mixture of alcohol diacrylate and ethoxylated 1,6-hexanediol diacrylate as monomer.

[0069] Components 1 to 6 in the amounts shown in the table below were mixed together at room temperature, and the mixture was stirred uniformly at 800 rpm using a EUROSTAR mixer from IKA-WERKE. Add matting powder slowly at 500rpm, and disperse the mixture at high speed at 1500rpm for 15-30 minutes until the fineness reaches 30 microns. Then tung oil was added, and the mixture was stirred evenly at a speed of 800 rpm to obtain coating composition-3 according to the present invention, which was a full-matte coating composition.

Abstract

The invention discloses a dual-cured matte paint composition. The composition comprises an irradiation curing component, an air drying component and a delustering agent. The irradiation curing component comprises one or more oligomers, one or more monomers and a photoinitiator. The air drying component comprises long oil alkyd resin and/or natural drying oil and/or polymerized natural oil. The invention discloses a method for preparing the dual-cured matte paint composition and a base at least partially coated with the dual-cured matte paint composition.

Description

field of invention [0001] The invention relates to the field of coatings, in particular to a dual-curing matte coating composition. Background technique [0002] In order to provide better surface protection and aesthetic properties, functional coatings are increasingly used on the surface of materials. According to the gloss of the paint, it can be divided into high-gloss paint and matte paint. [0003] High-gloss paint is also called "high-gloss paint" or "bright paint", and generally refers to a paint variety whose gloss is above 65° when measured at an angle of 60°. The paint film formed by high-gloss paint is full and bright, with high fullness and better decorative effect. However, high-gloss coatings will produce strong reflections in actual use, which will easily cause visual fatigue for users. High-gloss coatings have poor abrasion resistance and scratch resistance, and once damaged (such as scratches or dents), they will produce uncoordinated sensory defects. I...
