Abstract
The invention relates to a method for making a waterborne surface treatment agent by replacing solvent polyurethane resin with waterborne polyurethane resin. The waterborne surface treatment agent is formed by subjecting special additives and the waterborne polyurethane resin to compounding or modification, and is generally used for a synthetic leather top layer or surface layer, so that the synthetic leather can have a special surface effect and handfeel. The waterborne surface treatment agent provided in the invention has the advantages of no toxicity, environmental protection and safety, etc., and has consistent or similar performance with a solvent surface treatment agent.
Description
The present invention relates to the manufacture method that a kind of use polyurethane resin replaces water-based table place's agent of solvent borne polyurethane resin.
Synthetic leather, owing to using a large amount of plasticizer in manufacture process, after the high temperature foaming, tends to occur that plasticizer, on surface, is clamminess product surface, greasy.For the sense of touch that the synthetic leather surface has been reached, need to the gloss on synthetic leather surface can not only be regulated in the place's agent of top finishing last layer table, and the adhesion that plasticizer produces can be prevented and treated, prevent contamination by dust, and give synthetic leather the ox-hide feel is arranged.
Common synthetic leather table place's agent is solvent borne acrylic resin and polyurethane, and the solvent kind has butanone, toluene ring ethyl ketone, acetic acid butanone etc.These solvents are difficult for reclaiming and can't meeting European Union's ecological synthetic leather requirement, have both caused the wasting of resources, have caused again environmental pollution, more seriously, in the synthetic leather of making, volatile organic content is high, and carcinogenic is arranged, and can cause to people's health very large injury.
The objective of the invention is to solve the harm of solvent borne table place's agent to human body and environment.
Principle of the present invention is that the use polyurethane resin replaces the solvent borne polyurethane resin and special auxiliary agent is composite or modification and generate the place's agent of water-based table.The place's agent of water-based table is to take water as decentralized medium, there is the advantages such as nontoxic, environmental protection, safety, the place's agent of water-based table and the place's agent of solvent borne table do not have any difference in essence, and finally film forming is all polyurethane, but polyurethane molecular form in medium (water or solvent) is different.Because polyurethane molecular is WATER REPELLENCY in essence, just owing to having introduced hydrophilic radical in strand, by the external force Forced Dispersion in water, hydrophobic segment in molecule is assembled, hydrophilic segment is distributed in the surface of table place agent particle, a kind of thermodynamic instability state in essence, and the strand of solvent borne table place's agent is dissolved in solvent, strand is unfolded evenly, it is a kind of Thermodynamically stable state, this hydrophilic group because of molecular structure and particle state to have determined that the place's agent of water-based table has a filming performance good, strong covering power, bonding firmly, the performance that the physical property excellence of coating etc. are unique, greatly improved the grade of synthetic leather.
Being formulated as follows of water-based table place's agent of waterborne polyurethane resin replacement solvent borne polyurethane resin:
| Raw material | Deal | Ratio % |
| Waterborne polyurethane resin | 100 | 62.50 |
| Levelling agent | 20 | 12.50 |
| Defoamer | 20 | 12.50 |
| Organosilicon | 20 | 12.50 |
| Add up to | 160 | 100 |
Waterborne polyurethane resin replaces the characteristics of water-based table place's agent of solvent borne polyurethane resin:
1, the solvent of solvent borne table place agent can cause dissolving to the bottom of synthetic leather, and the place's agent of water-based table to the synthetic leather bottom without destruction, and make synthetic leather there is good feel.
2, pollution-free, the odorlessness of water-based table place agent, do not fire, not quick-fried, and consumption is few, low price, and anti-tensile, modulus, elongation and adhesiveness etc. all reach the requirement of solvent-borne type table place's agent.
3, the agent of water-based table place can need as smooth, waterproof and gloss etc. are adjusted to reach the resultant effects such as performance and aesthetic feeling according to the user.4, the agent of water-based table place has reduced toxic wastewater, discarded discharge, has greatly reduced the health hazard that organic solvent produces human body, can contaminated solution and occupational disease problem, and be the final development trend that synthetic leather is produced.
5, the synthetic leather that the agent of use table place is made has the characteristics of ecology, green, nontoxic, environmental protection, has in use reduced the infringement to consumer health and environment.
For example:
Add the synthetic leather that water-based table place's agent 2% of the present invention makes as follows with the synthetic leather comparative result without adding:
| Without the synthetic leather added | Add the synthetic leather of 2% water-based table place's agent |
| Texture is hard | Texture is soft |
| Without the skin and flesh sense | The skin and flesh sense is arranged |
| Without smooth feeling | Smooth feeling is arranged |
