Description
Technical field
The present invention relates to technical field of coatings, be specifically related to furniture lacquer, relate in particular to a kind of ultraviolet light polymerization furniture colored paint and preparation method thereof.
Background technology
As everyone knows, furniture, cabinet and Wood craft manufacturing enterprise surface paint coating process are main with spraying, and institute makes and paints normally NC.PU.PE, the simple easy construction of these traditional coating coating equipments, but a lot of shortcomings are arranged:
1, contain extremely lowly admittedly, the VOC quantity discharged is too high;
2, it is low that consolidating of filming contains, and the fullness ratio of filming is relatively poor; Curing cross-linked density is low, and hardness not high (generally less than 1H) is filmed and sunk easily, scratches, and resistant, solvent resistance are relatively poor;
3, in the construction process, envrionment temperature, the humidity effect effect of filming; The curing of coating time long (general 16～24 hours), be unfavorable for the industriallization pipelining; Influenced by workman's individual operations skill level, product qualified rate can not be controlled;
4, the spraying application waste is very big, spraying application, and general utilization efficiency of coatings is less than 60%.
Characteristics such as ultraviolet light polymerization (UV) coating is a kind of environmental type coating, and it has the solid content height, and the volatile solvent discharge is low, and curing speed is fast, and environment-friendly materials are projects that the our times various countries fall over each other to research and develop.
Ultraviolet-curing paint is the best substitute of traditional coating, and it can overcome the above-mentioned many shortcomings of traditional coating, is applied in the wood furniture industry rapidly, and becomes the development trend of domestic and international furniture application.
Summary of the invention
The objective of the invention is to the deficiency to prior art, provide that a kind of paint film property is good, construction process is not affected by environment, environment-friendly and green, can adopt roll coating model to be coated on the ultraviolet light polymerization furniture colored paint on the furniture.
Another object of the present invention is to provide the preparation method of above-mentioned ultraviolet light polymerization furniture colored paint.
Above-mentioned purpose of the present invention is achieved through following scheme:
A kind of roll coating model that adopts of inventor's pre-prepared is coated on the ultraviolet cured colored paint on the furniture; But in R&D process; Find in the composition of raw materials of this colored paint; Curing and film forming are two factors that key will solve, thereby therefore how to select component and adjust its consumption to obtain good solidification effect and film-formation result, then are emphasis of the present invention; After groping through conceptual design and experiment, the inventor obtains a kind of satisfactory ultraviolet light polymerization furniture colored paint.
A kind of ultraviolet light polymerization furniture colored paint, its composition of raw materials is made up of each component of following parts by weight:
15～45 parts of aliphatic polyurethane tetraacrylate;
15～35 parts of Dipentaerythritol five propenoate;
1～10 part of toner;
1～10 part of 1-Methoxy-2-propyl acetate;
1～15 part of N-BUTYL ACETATE;
5～25 parts of vinyl acetic monomers;
0.1～2 part of light trigger TPO;
1,173 0.2～3 parts of light triggers.
Above-mentioned aliphatic polyurethane tetraacrylate; After the inventor compares experimental study to multiple commercially available aliphatic polyurethane tetraacrylate; Select Chiba UV2100; Because after the aliphatic polyurethane tetraacrylate of this article number is used for the present invention, the film forming properties of the feasible colored paint that finally obtains is best; Those skilled in the art only need to buy Chiba UV2100 when preparation ultraviolet light polymerization furniture colored paint of the present invention, according to the consumption in the above-mentioned prescription it is added as raw material then to get final product;
Above-mentioned Dipentaerythritol five propenoate (DPHA) are to cooperate the aliphatic polyurethane tetraacrylate to use as monomer in this composition of raw materials, adopt any commercially available DPHA all can realize the present invention, the DPHA of preferred many yards productions of sand;
Above-mentioned toner is given the colored paint color and is used, and any toner when adopting those skilled in the art to prepare coating all can be realized the present invention, and preferred U.S. gift joins 595;
Above-mentioned 1-Methoxy-2-propyl acetate (PMA), pure acid butyl ester, ethyl glycolate and toluene all play the effect of solvent in this composition of raw materials;
The chemical name of above-mentioned light trigger TPO is 2,4,6-trimethylbenzoyl-diphenyl phosphine oxide; The chemical name of light trigger 184 is a 1-hydroxy-cyclohexyl phenyl ketone; The selection of these two kinds of light triggers can make colored paint of the present invention have good solidification effect.
In the composition of raw materials of above-mentioned ultraviolet light polymerization furniture colored paint, Chiba UV2100 provide good flexible, reaches the wettability to various toners; Light trigger TPO provides good deep layer to solidify, and after adding various tinting materials extraordinary ability to cure is arranged still; The collocation of other all kinds of SOLVENTS, the solvent agent that can obtain, and suitable evaporation rate reach good levelling and surface effect.
The preparation method of above-mentioned ultraviolet light polymerization furniture colored paint is that according to the above-mentioned raw materials prescription, with various component mixings, the process sand mill is ground to fineness less than 10 microns, promptly prepares required ultraviolet light polymerization furniture colored paint.
Compared with prior art, the present invention has following beneficial effect:
1. the present invention is a new technology that the uv radiation curing technology is applied to coatings for furniture; Traditional relatively coatings for furniture; Ultraviolet light polymerization furniture colored paint of the present invention uses the vinylformic acid reactive monomer replace solvents that can participate in reacting; Thereby do not contain volatile solvent, environment is not polluted, because ultraviolet light polymerization roller coat colored paint not containing benezene solvent and heavy metal element; Human body and environment are safe from harm, and are " environmental protection " products truly;
2. ultraviolet light polymerization furniture colored paint of the present invention is through uviolizing instantaneous crosslink film-forming, and hardness of film is high, and glossiness is high, and chemical resistant properties is good;
Since in the ultraviolet light polymerization roller coat colored paint pigment hindered ultraviolet penetrating, make the deep layer of filming be difficult to solidify, interlayer adheres to and does not reach requirement; So the present invention selects and dosage optimization through the component in the prescription, the deep layer that has solved ultraviolet light polymerization roller coat colored paint is solidified, interlayer adheres to and the global question of levelling;
4. ultraviolet light polymerization furniture colored paint selection appropriate light initiator of the present invention and ultraviolet wavelength are adaptive, help ultraviolet penetrating; Adopt the low molecule light-cured resin of special modification simultaneously, obtain the needed leveling characteristics of coating.
