Description
Technical field
The present invention relates to the acrylic resin modified energy-saving and environment-friendly paint of a kind of refrigerator backboard.
Background technology
Acrylic resin is the resin be made up of acrylate and methacrylic ester and other olefinic type monomers copolymerization, compared with other synthetic macromolecule resins, acrylic resin has many outstanding advantages, as fast light, the weathering resistance of excellence, open air weather resistance of being exposed to the sun is strong, ultraviolet resistance irradiates and not easily decomposes and turn yellow, original gloss and color and luster can be kept for a long time, good heat resistance, the chemical such as good acid-and base-resisting, salt, grease and washing composition are had to stain and corrosive nature, fabulous snappiness and minimum pigment reactivity.Therefore, have a wide range of applications automobile, household electrical appliances, art metal furniture, coiled material industry, instrument, building, textiles, woodwork, papermaking and plastics etc. are industrial.
But the heat that the linear structure of acrylic resin causes sticks cold short, anti-after-tackiness and thermotolerance is not good etc. that shortcoming has a definite limitation to its range of application.The equal phase structure of acrylic resin makes its cold tolerance and resistance toheat be difficult to take into account, and as increased resistance to low temperature, then can lose resistance to elevated temperatures, vice versa, and thus common acrylic acid or the like coating and decorating material just inevitably exists above-mentioned shortcoming.
By with other monomers, resin copolymerization and modification, the various aspects of performance of coating can be changed, make the coating of multiple different performance and Application Areas.Epoxy modified acrylic resin introduces propenyl unsaturated double-bond at the two ends of epoxy molecule chain, then with other monomer copolymerizations, like this, just make the various premium properties (fullness ratio of epoxy resin, gloss, hardness, sticking power etc.) be not fully exerted in acrylic resin, over-all properties respectively gets the chief, its dryness, fullness ratio, gloss, the over-all propertieies such as hardness are better than general acrylic resin, be applicable to the extra high occasion of cosmetic requirement, as frosting application, to meet the use of plastics, the course of processing is as surface treatment, plating, gold stamping, the needs of plated film etc.
At present, the following epoxy modified acrylic resin coating of domestic existence:
Chinese patent CN201210564995.5, disclosing a kind of take acrylic resin as the coating of raw material, is grouped into: epoxy resin 30 ~ 60 by the one-tenth of following weight part; Thermoplastic acrylic resin 20 ~ 30; Fire retardant 10 ~ 15; Zinc oxide 10 ~ 20; Pigment 10 ~ 15; Methyl alcohol 1 ~ 3; Deionized water 10 ~ 15.But, although this patent lists epoxy resin and thermoplastic acrylic resin, do not form the combination of epoxy modified acrylic resin, coating cannot be made to possess the premium properties of epoxy modified acrylic resin.
In addition, the application mode of existing acrylic resin paint adopts spray-coating mostly, such as Chinese patent CN201310607469.7, disclose a kind of thermosetting acrylic resin used for powder coating, this resin ester is equipped with the thermosetting powder coating(s) that unclassified stores is made, the film formed after spraying, has excellent weathering resistance, good flow leveling, excellent surface hardness and high-luster, weather resistance and decorate properties; Can be used for indoor or outdoors shape or material of construction.TGIC can be substituted to a certain extent, avoid the use of toxic substance.
But spraying is by spray gun or dish-style spraying gun, by means of pressure or centrifugal force, is dispersed into even and fine droplet, is applied over the coating process on coated article surface.Subject matter in spraying is the coating cloud of high dispersing and the solvent (i.e. volatile organic contaminant, VOCs) evaporated, and both contaminate environment, are unfavorable for HUMAN HEALTH, waste coating again, cause financial loss.Volatilization, the coating be diffused in air, then form volatile organic contaminant, be detrimental to health.At painting workshop, coating, as the main source of volatile organic contaminant, is easy to cause acute poisoning during volatile organic compounds excessive concentration in air in painting workshop, and the lighter there will be headache, dizziness, cough, Nausea and vomiting or is dead drunk liquor-saturated shape; Severe one there will be liver poisoning and even goes into a coma very soon, and what have also may be in peril of one's life.Treat for a long time, in the painting workshop of volatile organic compounds pollution, can chronic poisoning be caused, damage liver and neural system, cause general weakness, drowsiness, skin pruritus etc.What have also may cause endocrine disturbance, affects sexual function; Benzene and dimethylbenzene can also damage system, so that cause leukemia.
Summary of the invention
The object of the present invention is to provide the acrylic resin modified energy-saving and environment-friendly paint of a kind of refrigerator backboard, described coating adopts bisphenol A epoxide resin acrylic resin modified, described coating is made to have excellent fire-retardant and wear resisting property, and curing speed is fast, also there is good mechanical property, ageing-resistant performance and resistance to chemical corrosion, strong adhesion, ductility are good, high temperature resistant, long service life, change complete processing, roller coat process concentrated by refrigerator backboard slab, simplify machining clearance, without the need to arranging painting workshop separately.
