Description
Technical field
The invention belongs to paint field, it is related to a kind of water-based gloss oil and its preparation method and application.
Background technique
Currently, the appearance coating on carbon fiber bicycle, in the market still based on oiliness, so, unavoidably, VOC row
It is high-volume big, while having certain harm to environment and human body.Currently, water paint replaces oiliness molten with water as decentralized medium
Agent is gradually widely used.And water paint applies the application loaded onto carbon fiber bicycle appearance, greatly meets producer
Pursue the coating demand of environmental protection, low toxicity.
But water paint especially water-based gloss oil is compared with the oiliness gloss oil of same type, there are still certain performance gap,
It is embodied in the oiliness gloss oil that hardness, wet-film thickness, gloss, drying property etc. are not so good as same type.
CN108587363A discloses a kind of environmentally friendly high abrasion high glaze water-based gloss oil, by following components in percentage by weight
Composition: environment-friendly water-based acrylic resin: 35-45%；Self-desiccation aqueous acrylic emulsion: 35-45%；High abrasion modified waxes cream
Liquid: 1-5%；BYK defoaming agent: 0.5-1%；BYK levelling agent: 1-5%；Anti-curling auxiliary agent: 0.5-2%；Scratch resistance auxiliary agent: 1-
5%；Deionized water: 5-8%.Compared with prior art, paper shrinkage crimping can be effectively avoided, wearability and smooth degree are high,
It can dry thoroughly, VOCs residual is low, but this water-based gloss oil does not have the performance of scratch resistance and high rigidity.
CN108385435A discloses a kind of water-based gloss oil, by weight percentage, including 6%~8% microencapsulation
Melamine organic phosphate, 4%~40% nuclear monomer, 4%~5% shell monomer, 0.1%~0.2% emulsifier,
0.1%~0.2% initiator, 0.3%~0.5% pH adjusting agent, 0.1%~1.8% auxiliary agent, 45%~85% are gone
Ionized water.This water-based gloss oil has good heat-insulated, oxygen barrier, fire-retardant and suppression hood, can also avoid having in water-based gloss oil
The defects of machine phosphorus fire retardant is easy to migrate, the easy moisture absorption improves the compatibility of organophosphorous fire retardant and water-based gloss oil matrix, ensure that water
The glossiness and mechanical strength of property gloss oil.The water-based gloss oil is coated in the surface of corrugated board and corrugated paper products, can be made
Corrugated board and corrugated paper products have biggish improvement in terms of fire-retardant, water resistant, grease proofing, mechanical strength.This water-based gloss oil
It mainly applies on corrugated board, but its is scratch resistant ineffective.
CN105969028A discloses a kind of fire resistant water-based gloss oil and preparation method thereof, and water-based gloss oil includes following components
And the content of parts by weight: 70-90 parts of film-forming resin, 1-10 parts of solvent and 5-10 parts of auxiliary agent；Wherein, film-forming resin is aqueous phenylpropyl alcohol
Olefin(e) acid resin, solvent be deionized water and ethyl alcohol mixed solvent, auxiliary agent include organosilicon or polythene wax emulsion one kind or
Two kinds；When preparation, film-forming resin is placed in agitator by weight, under stirring, auxiliary agent is added by weight, continues
Stirring, adds solvent, stirs evenly, and adjustment viscosity was to Chai Shi 4# cup 15 ± 2 seconds, pH value 8.0 ± 0.5.With existing skill
Art is compared, and water-based gloss oil has preferable levelability and film surface flatness, has good printing to adapt on the surface of various paper
Property, the integrality and beauty of printed matter are protected, preparation process is simple, and gained finished product stability is good, saves production cost, is suitable for
Commercial scale, high efficiency mass production.The problem of water-based gloss oil master that this method provides is to solve high temperature resistant and flatness,
The performance of scratch resistance, hardness can not be promoted.
And currently, water-based gloss oil is in certain specific fields, it is desirable that there is high hardness and good adhesion strength, such as
What, which is developed, a kind of with good resistance to marring, high rigidity while having both excellent paint film appearance for its answering in specific area
With having great importance.
