Abstract
The invention provides a water-based ultraviolet light curing coating with a smell removing and matte function, which comprises the following components in parts by weight: 100-200 parts of aqueous polyurethane acrylic ester; 2-5 parts of photoinitiator; 10-20 parts of filler; 0.5-3 parts of auxiliary agent; 10-20 parts of composite deodorant; 20-50 parts of water; wherein the composite odor removing agent contains a nano photocatalyst and a micropore-medium Kong Dianfen-based carbon sphere composite material. The water-based ultraviolet light curing coating disclosed by the invention has the performance of purifying air and absorbing TVOC harmful gases such as formaldehyde which is not generally possessed by conventional coatings, does not need to be added with an organic solvent, is environment-friendly, and has good adhesive force, high toughness, weather resistance and chemical stability.
Description
Technical Field
The invention relates to the field of surface protection of floors, wallboards and wood floors, in particular to a preparation method of a matte water-based ultraviolet light curing coating with a smell removing function.
Background
The ultraviolet curing coating has the advantages of no pollution, high curing efficiency and the like, and is rapidly developed and is mainly applied to different fields of wood coating, building materials, electronic communication, automobile parts and the like. Meanwhile, the water-based ultraviolet light curing coating has the advantages of no Volatile Organic Compound (VOC), little environmental pollution, high curing speed, energy conservation, better curing product performance than high-speed automatic production and the like. The traditional paint is easy to volatilize and has low curing speed, which is not beneficial to environmental protection. Therefore, the aqueous ultraviolet light curing coating is a main substitute for the traditional coating. Meanwhile, environmental protection products are uneven in modern furniture decoration, common furniture consumers containing formaldehyde and other TVOC harmful gases are difficult to distinguish, and the harm to the health of the consumers is possibly caused, so that the development of the water-based ultraviolet curing paint with the odor removing function has great practical value and wide market prospect.
Disclosure of Invention
The technical problems to be solved are as follows: the invention aims to solve the problem of odor removal, formaldehyde and other TVOC gas adsorption and decomposition performance which are not generally possessed by conventional coatings, and provides a preparation method of a water-based ultraviolet light curing coating with an odor removal function.
The technical scheme is as follows: the water-based ultraviolet light curing coating with the odor removing and matte functions is characterized by comprising the following components in parts by weight:
100-200 parts of aqueous polyurethane acrylic ester
2-5 Parts of photoinitiator
10-20 Parts of filler
0.5-3 Parts of auxiliary agent
10-20 Parts of composite deodorant
20-50 Parts of water;
Wherein the composite odor removing agent contains a nano photocatalyst and a micropore-medium Kong Dianfen-based carbon sphere composite material.
Preferably, the aqueous polyurethane acrylate is polyether aqueous polyurethane acrylate, polyester aqueous polyurethane acrylate or a combination of any one or two or more than two of the aqueous polyurethane acrylate and the polyester aqueous polyurethane acrylate;
The photoinitiator is any one or more than one mixture of 2-hydroxy-2-methyl-1-phenyl-1-acetone, 1-hydroxy-cyclohexyl phenyl ketone, 2,4, 6-trimethyl benzoyl diphenyl phosphine oxide, benzoin diethyl ether or benzoin dimethyl ether;
The filler is any one or more than one mixture or two or more than two compounds of silicon dioxide, aluminum stearate or calcium stearate with the particle size grade of micro powder or nano grade;
The auxiliary agent comprises any one or two or more of superfine synthetic silicon dioxide, ceramic powder, a water-based thickener, a defoaming agent, a formaldehyde removal additive, an antibacterial additive, an anti-sedimentation agent, a matting agent, a handfeel wax and a dispersing agent.
Preferably, the preparation method of the nano photocatalyst and microporous-medium Kong Dianfen-based carbon sphere composite material comprises the following steps:
