The water-based PU bright surface brush clear varnish has the advantages that the mixture ratio of the component is scientific and reasonable, and the components are coordinated with each other and act together; the bright surface brush clear varnish has the advantages of good film reforming property, firm bonding, solvent resistance, hydrolysis resistance and thermosenescence resistance of coating; the finished product made of the synthetic leather, the surface of which is treated by the bright surface brush clear varnish, has the advantages that the original effect of the leather surface is not affected, the treated leather surface has unique slippery effect, and the synthetic leather has good comprehensive effects of good air permeability, good hand feel, water resistance, cohesiveness and the like.
Description
Technical field
The present invention relates to a kind of use for synthetic leather water-based PU bright surface brush clear varnish, particularly a kind of use for synthetic leather water-based PU bright surface brush clear varnish that is applied to synthetic leather rear section technology.
Background technology
Along with the raising of people's life water product, people pursue high-quality daily product gradually, and the demand of leather products is more and more, and along with the enhancing of animal protection consciousness, animal corium can not satisfy people's demand.At present, the synthetic leather product becomes following popular trend gradually, synthetic leather has been widely used in products such as producing case and bag, clothes, footwear, the base fabric of PU leather is the good canvas PU material of tensile strength, except can being coated in base fabric top, in the middle of base fabric can also being included in, make it outward appearance and can't see the existence of base fabric, it is good that PU leather has physical property, and anti-complications, pliability is good, tensile strength is big, have gas permeability, so PU removes from office and is widely used in the lining of footwear or the position that case and bag bear weight.After the PU leather is synthetic, often need handle and the leather that obtain having the different performance characteristics with some surface conditioning agents, bright surface brush clear varnish is a surface conditioning agent commonly used in the synthetic leather, and synthetic leather can produce after bright surface brush clear varnish is handled significantly wipes chromatic effect, is subjected to people's extensive favor.
At present, the use for synthetic leather of selling on the market is wiped the agent of look finishing agent and is generally the place's agent of solvent-borne type cloudy surface table, and it has the following disadvantages:
1, the organic solvent that contains in the place's agent of solvent-borne type oil fog face rubbing surface treatment can cause the bottom dissolving of synthetic leather or artificial leather, and synthetic leather feel after treatment is bad, and effect is single;
2, not only cost is higher, smell is bigger for the organic solvent that contains in the agent of solvent-borne type fog face rubbing surface treatment place, easy contaminated environment, and have potential safety hazards such as inflammable, explosive;
3, the synthetic leather product for preparing of solvent-borne type cloudy surface table place's agent, resultant effects such as its viscosity, stability, hand sense of touch are not good.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is to overcome the deficiency that solvent-borne type fog face rubbing surface treatment finishing agent exists, and provides a kind of and anti-ly opens, resultant effects such as modulus, elongation and adhesiveness are good, are the use for synthetic leather water-based PU bright surface brush clear varnish of solvent with water
Technical scheme: for solving above technical problem, the present invention takes following technical scheme:
A kind of use for synthetic leather water-based PU bright surface brush clear varnish, it is made up of the raw material of following parts by weight: 35～45 parts of waterborne polyurethane resins, 50～65 parts in water, 0.5～1 part of organosilicon levelling agent, 2～5 parts of silicone defoaming agents.
As preferred version, use for synthetic leather water-based PU unctuousness finishing agent of the present invention, it is made up of the raw material of following parts by weight: 40～45 parts of water-borne acrylic resins, 55～65 parts in water, 0.5～1 part of organosilicon levelling agent, 0.5～1 part of silicone defoaming agent.
Wherein waterborne polyurethane resin is the matrix resin of use for synthetic leather water-based PU bright surface brush clear varnish of the present invention, described crosslinking polyurethane resin, film forming is transparent product body shape, resilience is good, and the anti-tortuosity that tool is good, cold resistance, soft in the film forming, good dispersion, water proof and wearable are wiped, and rate of drying reaches good resistance to blocking, the characteristics of high glaze soon.
Wherein the water as retarder thinner is common running water, has avoided the use of organic solvents such as dimethyl formamide, butanone, environmental protection and saving cost.
The preparation method of use for synthetic leather water-based PU bright surface brush clear varnish provided by the invention may further comprise the steps:
1. choose in proportion polyurethane resin,, silicone defoaming agent, organosilicon levelling agent and water, mix, stirred 2 to 3 hours, fully mixing;
2. get the mixture 200 orders filtration that 1. step reacts gained; Promptly get described use for synthetic leather water-based PU bright surface brush clear varnish.
The used water of above preparation method can be common running water.
Beneficial effect: water-based PU bright surface brush clear varnish provided by the invention is compared with solvent-borne type PU cloudy surface wiping look finishing agent in the prior art has following advantage:
1, the used solvent of unctuousness finishing agent provided by the invention is a water, have do not fire, safety, environmental protection, cost-effective performance.
2, bright surface brush clear varnish provided by the invention, show through experimental study, each set of dispense of forming bright surface brush clear varnish is than scientific and reasonable, coordination, acting in conjunction mutually between component, bright surface brush clear varnish have good film-forming property, bonding firmly, the anti-solvent of coating, cold-resistant, hydrolysis, heat-proof aging advantage, handle the finished product of making behind the synthetic leather surface with bright surface brush clear varnish provided by the invention, having does not influence that its leather surface is former to produce effect, and has unique wiping chromatic effect.
3, this water-based PU bright surface brush clear varnish is used on existing synthetic leather production line, be need not to change the production technology and the equipment of existing synthetic leather, can not increase the synthetic leather production cost of products.
4, the preparation method of water-based PU bright surface brush clear varnish provided by the invention is workable, production efficiency is high, cost is low, environmental protection, can realize industrialized production.
