Description

A kind of ultraviolet light cured burnished paint and preparation method thereof
Technical field
The present invention relates to a kind of ultraviolet light cured burnished paints and preparation method thereof.
Background technique
Recently as continuous improvement of people's living standards, requirement of the people to quality of life is also higher and higher.For Articles for daily use constantly pursue completely new, comfortable experience no matter in appearance or sense of touch.Therefore many height of current era Shelves articles start to attract public attention with beautiful, comfortable shape and sense of touch.The application of dumb light coating is also just come into being. It is with beautiful appearance, comfortable Human physiology sense of touch, gradually in industries such as automobile interior decoration, electronic products, Zhan get Yi seat it Ground, and increasingly obtain more favors.
But now the technology of production low luster coating is added one into the system of coating mainly using inorganic filler is added Quantitative delustring auxiliary agent, silica or aluminum oxide of predominantly various partial sizes etc..Since the introducing of this auxiliary agent can not So that system is dissolved each other with filler, coating is made to be in a kind of unstable state, storage and in use, sinking due to filler in the later period Drop may cause, and inorganic filler is located at container bottom, influences the Painting effect in later period, cause adverse effect to production.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the existing defects, provides a kind of ultraviolet light without inorganic filler Light cured burnished paint and preparation method thereof.
In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions:
A kind of ultraviolet light cured burnished paint is made of the component B of the component A and 75~55wt% of 25~45wt%,
Wherein, component A is to be reacted by polyethylene glycol adipate, isophorone diisocyanate and hydroxy-ethyl acrylate The urethane acrylate arrived;
Component B includes nine degree of functionality urethane acrylates, three-functionality-degree urethane acrylate, dipentaerythritol 6 third Olefin(e) acid ester, three (2- ethoxy) isocyanuric acid triacrylates, 1,6 hexanediol diacrylate, five acrylic acid of dipentaerythritol Ester and crack type photoinitiator.
Preferably, according to parts by weight, component A is by 30-50 parts of polyethylene glycol adipate, isophorone diisocyanate 35-45 parts and hydroxy-ethyl acrylate 10-20 parts should obtain.
Preferably, it is added in the reaction of polyethylene glycol adipate, toluene di-isocyanate(TDI) and hydroxy-ethyl acrylate anti- Oxidant, polymerization inhibitor and catalyst.Preferably, the antioxidant is 2,6- di-tert-butyl-4-methy phenol, and dosage is 2~5 Parts by weight, the polymerization inhibitor are p-hydroxyanisole, and dosage is 2~5 parts by weight, and the catalyst is di lauric dibutyl Tin, dosage are 2~5 parts by weight.
Preferably, in component B, the parts by weight of each raw material are as follows: nine 5~30 parts of degree of functionality urethane acrylates, three 5~25 parts of degree of functionality urethane acrylate, 5~20 parts of double pentaerythritol methacrylate, three (2- ethoxy) isocyanide ureas 10~40 parts of sour triacrylate, 30~50 parts of 1,6 hexanediol diacrylate, double pentaerythritol C5 methacrylate 5~15 Part, 3~9 parts of crack type photoinitiator.
Preferably, the crack type photoinitiator by 1~5 parts by weight 1- hydroxycyclohexyl phenyl ketone and 1~5 weight 2- hydroxy-2-methyl -1- phenyl -1- acetone the composition of part.
Above-mentioned ultraviolet light solidifies the preparation method of flexible low luster coating, comprising:
(1) first under antioxidant, polymerization inhibitor effect, ethylene glycol adipate is reacted with toluene di-isocyanate(TDI), reaction After the completion, hydroxy-ethyl acrylate and catalyst are added, the component A reacted;
(2) by nine degree of functionality urethane acrylates, three-functionality-degree urethane acrylate, six acrylic acid of dipentaerythritol Ester, three (2- ethoxy) isocyanuric acid triacrylates, 1,6 hexanediol diacrylate, double pentaerythritol C5 methacrylate and Crack type photoinitiator mixes, and obtains component B.
Preferably, the reaction temperature of step (1) is 60~80 DEG C.
A kind of ultraviolet light cured burnished coating, by mixing above-mentioned group A with component B, ultraviolet light solidifies to obtain.
The coating that coating of the present invention is formed has good flexibility, also has both excellent hardness, and be added without delustring The advantages that filler can reach matte effect, and curing rate is fast, energy conservation and environmental protection.The invention avoids existing low luster coating is main Matte effect is obtained by the way that inorganic filler is added simultaneously again because filling settlement, dispersion unevenness cause to store unstable problem. It can be widely applied to gradually in decoration industries such as automobile interior decoration, electronic products.
