Abstract
The invention relates to a water-based PU brightening coating agent for artificial leather. The agent comprises, calculated by a total weight of resin, 10-20% of water-soluble acrylic resin, 10-20% of water-based paint resin, 50-60% of water, 3-5% of a modified organosilicon polymer, 0.5-1% of an organosilicon flatting agent, 2-5% of an organosilicon defoaming agent, and 0.5-2% of a waterborne polyurethane thickener. The agent provided by the invention uses water as a solvent to substitute toxic solvents, such as DMF and MEK; and a product gains characteristics of no combustibility, toxicity or environmental pollution, so as to fundamentally eradicate poison problem caused by solvent-type slurry for artificial leather.
Description
Technical field
The present invention relates to used for artificial leather water-based PU blast coating agent, particularly be applied to the used for artificial leather water-based PU blast coating agent of artificial leather last part technology, belong to the Innovation ﹠ environment Material Field.
Background technology
At present, the used for artificial leather finishing agent of selling on the market is generally solvent-borne type, and it has the following disadvantages:
1, the organic solvent in the agent of solvent-borne type table place can cause the bottom dissolving of artificial leather or artificial leather, and artificial leather feel after treatment is bad;
2, not only cost is higher, smell is larger for organic solvent, and environmental pollution is serious, and has the potential safety hazards such as inflammable, explosive;
3, not good for the treatment of the resultant effect of artificial leather.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is that the deficiency that overcomes the solvent treatment existence provides a kind of water-based blast coating agent, anti-of this water-based blast coating agent, modulus, elongation and adhesiveness etc. all reach the requirement of solvent-borne type finishing agent, and its resultant effect is good, production cost is low.
Technical scheme: for solving above technical problem, the present invention takes following technical scheme:
A kind of used for artificial leather water-based PU blast coating agent, it is comprised of the raw material of following percentage by weight: waterborne polyurethane resin 10～20%, water-based stoving paint resin 10～20%, water 50～60%, water-based hydroxyl crosslinking agent 5～6%,, organosilicon levelling agent 0.5～1%, silicone defoaming agent 2～5%, aqueous polyurethane thickener 0.5～2%.
Blast coating agent institute water can be common running water.
Beneficial effect: owing to adopting above technical scheme, the present invention compared with prior art has following advantage:
The present invention has overcome the shortcoming of solvent-borne type PU blast coating agent, and its adhesive force is good, and feel and effective has soft handle with the artificial leather product of its production, and moisture-penetrable ventilated property is good.In addition, water-based PU blast coating agent also has the advantages such as baking temperature is low, production cost is low, and the organic solvent-free volatilization is beneficial to environmental protection.
The specific embodiment
Further set forth the present invention below in conjunction with embodiment, but be not limited to this example.
Used for artificial leather water-based PU blast coating agent is comprised of following raw material components: 70 parts of waterborne polyurethane resins (30% solid content), 70 parts of water-based stoving paint resins, 180 parts of ordinary tap water, silicon modified organic polymer 5,35 kilograms of water-based hydroxyl crosslinking agents, 4 parts of aqueous polyurethane thickeners, 0.8 part of silicone defoaming agent, 2 parts of organosilicon levelling agents.
The production technology of inventor's fabricate-leather use PU blast coating agent is as follows:
Step 1: water-borne acrylic resin, water-based stoving paint resin, silicon modified organic polymer, silicone defoaming agent, organosilicon levelling agent, water are added together stirring 2 hours by prescription.
Step 2: the mixture of step 1 gained is stirred.
Step 3: step 2 gained mixture is filtered.
Step 4: namely get described used for artificial leather water-based PU blast coating agent after aqueous polyurethane thickener stirs with adding in the step 3.
The technical performance index of above-mentioned table place's agent sees Table 1:
Table 1
| Project | Detect index | Testing result |
| PH value | 6.5~7.5 | 7.0 |
| Outward appearance | The white thick liquid | The white thick liquid |
