Abstract
The invention discloses a water-based PU brush surface conditioning agent for synthetic leather, which comprises the following materials by weight percent: 10 to 20 percent of water-based stoving varnish resin, 1 to 6 percent of water-based polyurethane, 60 to 70 percent of water, 5 to 13 percent of silicon dioxide matting agent, 0.5 to 2 percent of organic silicon flatting agent, 1 to 5 percent of organic silicon foam killer and 2 to 6 percent of water-based modified polyethylene wax emulsion. In the water-based PU brush surface conditioning agent for synthetic leather, water is taken as solvent to replace noxious solvents, such as dimethyl formamide and butanone, so that the water-based PU brush surface conditioning agent has the performances of non-inflammation, safety, environmental protection and cost saving, and resin has the advantages of good film reforming property, firm bonding, solvent resistance, cold resistance, hydrolysis resistance and thermosenescence resistance of coating, and the finished product made of the surface conditioning agent has unique brush effect, strong dermis effect, water resistance and good air permeability.
Description
Technical field
The present invention relates to a kind of use for synthetic leather water-based PU resin, particularly a kind of water-based PU brush surface conditioning agent for synthetic leather 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.
At present, the use for synthetic leather resin of selling on the market is generally solvent type resin, and it mainly has the following disadvantages:
1, the organic solvent that contains in the agent of solvent-borne type brush surface conditioning place can cause the bottom dissolving of synthetic leather or artificial leather, and synthetic leather feel after treatment is bad;
2, not only cost is higher, smell is bigger for the organic solvent that contains in the agent of solvent-borne type brush surface conditioning place, easy contaminated environment, and have potential safety hazards such as inflammable, explosive;
3, the synthetic leather product for preparing of solvent-borne type brush surface conditioning place agent, resultant effects such as its 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 the agent of solvent-borne type brush surface conditioning place exists in the prior art, provide a kind of and anti-open, resultant effects such as modulus, elongation and adhesiveness are good, are the water-based PU brush surface conditioning agent for synthetic leather of solvent with water.
Technical scheme: for solving above technical problem, the present invention takes following technical scheme:
A kind of water-based PU brush surface conditioning agent for synthetic leather, it is made up of following raw materials by weight percent: water-based stoving paint resin 10～20%, aqueous polyurethane 1～6%, water 60～70%, silica flatting silica 5～13%, organosilicon levelling agent 0.5～2%, silicone defoaming agent 1～5%, watersoluble modified polythene wax emulsion 2～6%.
As preferred version, water-based PU brush surface conditioning agent for synthetic leather provided by the invention, form by following raw materials by weight percent: water-based stoving paint resin 15～20%, aqueous polyurethane 2～4%, water 60～70%, silica flatting silica 8～11%, organosilicon levelling agent 0.5～1.5%, silicone defoaming agent 2～3%, watersoluble modified polythene wax emulsion 3～5%.
Matrix resin of the present invention is the water-based stoving paint resin, the water-based stoving paint resin can be carboxy acrylic and the aliphatic polyurethane grafting forms, wherein the water-based stoving paint resin can with the aqueous polyurethane cross-linking reaction, prepare water-based stoving paint, be fit to preparation the high synthetic leather of apparent index requests such as gloss, richness.Water-based stoving paint resin of the present invention has excellent crosslinked hardness and recoatability advantage preferably, can adopt wetly to bump wet or wet and bump dried prepared.And water-based stoving paint resin polarity is bigger, and it is diluent with water, has avoided the use of organic solvents such as dimethyl formamide, butanone, environmental protection and saving cost.
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 water-based PU brush surface conditioning agent for synthetic leather provided by the invention may further comprise the steps:
1. choose the water-based stoving paint resin in proportion, aqueous polyurethane, the organosilicon levelling agent, the watersoluble modified polythene wax emulsion of silicone defoaming agent and water mixes, stirs;
