According to the invention, acrylamide morpholine is dispersed at a high speed and interpenetrated and embedded in the water-based UV resin, the water-based UV resin is physically modified, and various types of initiators are compounded, so that the water-based UV gloss oil has the advantages of high gloss, good fullness, high hardness, good chemical resistance, high curing speed, capability of being boiled in hot water at 80 +/-5 ℃ for 24 hours and the like, and compared with the conventional UV coating in the existing market, the water-based UV gloss oil has the advantages of yellowing resistance, hot water resistance, environmental protection, safety and the like.
Description
Technical Field
The invention relates to the technical field of coatings, and particularly relates to boiling-resistant water-based UV gloss oil for a bathroom and a preparation method thereof.
Background
In recent years, with the more and more popularization of the finely decorated houses and the successive emergence of national policies of industrialized and low-carbon environment-friendly houses, industrial technologies are continuously innovated, the integrated bathroom starts to jump to the 'blue sea' bathroom, and the assembly type integrated bathroom will meet the great outbreak. However, the integrated bathroom wallboards in the current market are usually coated with ceramic tiles and artificial granite substrates or UV coatings, and the ceramic tiles and the artificial granite need to be fired at high temperature, so that the energy consumption is high and the yield is low.
The problems with conventional UV coatings are also not negligible: the UV curing coating uses a large amount of active monomers as diluents to reduce the viscosity, the active monomers are difficult to completely react in the UV curing process, the residual monomers have potential influence on the physical properties of a paint film and the health safety of users, and particularly, some active diluents have odor, have strong stimulation effect on the skin, eyes and mucous membranes of a human body and generate anaphylactic reaction. Even in a UV curing system with low monomer content, the monomers are difficult to react completely in the curing process, and the reactive diluent can be continuously released after the monomers are cured to form a film. With the stricter of national environmental regulations, the environmental protection advantage of the water-based paint is more and more important, and the low viscosity of the water-based paint which is easy to adjust and the viscosity of the water-based paint which is adjusted to a very wide viscosity range become one of the main directions of paint development.
The aqueous UV oligomer used in the aqueous UV coating disperses in water, so that water can be used as a diluent, and the addition of a reactive diluent can be substantially avoided, and the aqueous UV curable coating has many advantages: for example, because the aqueous UV resin is dispersed in water in the form of emulsion or dispersion, the limitation of high polymer viscosity on molecular weight is eliminated, the aqueous UV resin can achieve very high molecular weight, and particularly can achieve high molecular weight linear resin which is difficult to achieve by the conventional UV resin; the high molecular weight and low crosslinking density of the water-based UV resin can solve the contradiction water-based system of high hardness and high toughness that the traditional oil-based coating can not have at the same time; most of the thickening agents and the rheology modifiers thicken the water phase, and the water-based UV coating takes water as the continuous phase, so that the rheology can be more conveniently adjusted; by adjusting the viscosity and the rheological property, the water-based UV coating can be suitable for general coating modes such as spraying, roller coating and brush coating, and equipment is easy to clean; the water-based UV coating can be directly diluted by adding water, and an extremely thin coating can be obtained by adjusting the solid content of the formula.
The water-based UV curing technology combines the characteristics of safety and environmental protection of the water-based paint and the characteristics of energy conservation and rapid curing of a UV curing system. The aqueous UV curing system can be divided into two systems of water-soluble type and aqueous emulsion type. The water-soluble UV curing system can directly use water as a diluent of the resin, thereby greatly reducing VOC and potential risks, and the water as the diluent is very safe and cheap, thereby reducing the cost. The aqueous emulsion type UV curing system can use the emulsion of high molecular weight UV resin, so that the crosslinking density of the formed film is lower, the curing shrinkage caused by monomers and high-functionality oligomers can be avoided, the problem that the traditional UV curing system cannot meet the requirements of high hardness and high toughness at the same time can be solved, and the aqueous emulsion type UV curing system has better film coating performance and curing film performance. The advantages of waterborne UV coatings are clear, but there are still some disadvantages to their use as coatings. For example, the water-based UV resin contains a large amount of hydrophilic groups, so that the water resistance of the coating film deteriorates. Aiming at the defect of poor water resistance of the aqueous UV resin, the method is improved by means of modifying the aqueous UV resin, designing components and the like.
Disclosure of Invention
In order to solve the technical problems in the prior art, the invention provides the water-based UV gloss oil which has the advantages of high gloss, quick curing, high hardness, scratch resistance, acid and alkali resistance and good boiling resistance, does not have bubbling cracking after being applied to a base material to form a film and boiled for 24 hours at 80 +/-5 ℃, and is particularly suitable for coating the bathroom wallboard.
The technical scheme of the invention is as follows: the water-boiling resistant water-based UV gloss oil comprises the following raw material components in parts by weight:
the existing waterborne UV resin still has water absorption after photocuring due to hydrophilic groups carried on a molecular chain, and the product has low water resistance and chemical resistance. The bathroom environment is especially humid and watery, and the coatings used for bathroom wall panel coating often contact cold water and hot water and are prone to foaming and falling off. According to the invention, the acrylamide morpholine is embedded into the water-based UV resin through high-speed dispersion and interpenetration, and the water-based UV resin is subjected to cold splicing modification, so that the obtained water-based UV gloss oil not only has the advantages of high hardness, high gloss and transparency, high physical property, good fullness, good compatibility and water resistance, but also has the advantages of high curing speed, good adhesion, excellent boiling resistance and excellent acid and alkali resistance.
Preferably, the water boiling resistant water-based UV gloss oil disclosed by the invention further comprises the following raw material components in parts by weight: 3.0-5.0 parts of nano aluminum oxide. The nano alumina particles are uniformly distributed among the resin particles through high-speed dispersion, and the characteristics of good thermal stability and no influence on gloss of the nano alumina particles are utilized for reinforcement, so that the problem of hot water boiling resistance of the water-based UV gloss oil is further effectively solved.
Preferably, in the boiling-resistant aqueous UV gloss oil, the minimum film-forming temperature of the aqueous UV resin is 0 ℃, the functionality is 9, and the solid content is 40.0 +/-1%. After the UV coating is cured, the basic performance of a coating film is greatly determined by a main film-forming material, namely UV resin, and the performance of the UV resin is determined by a high molecular polymer forming the resin, and the molecular structure, the molecular weight, the double bond density and the like of the polymer influence the performance of the resin.
Preferably, the aqueous UV resin of the present invention is an aqueous UV polyurethane resin, and more preferably an aqueous urethane acrylate oligomer.
