Abstract
The invention relates to a water-based adhesive for shoes. The water-based adhesive is characterized by consisting of the following components in part by weight: 70 to 95 parts of water-based polyurethane glue, 3 to 8 parts of external cross-linking agent, 0.1 to 0.5 part of wetting agent, 0.1 to 0.5 part of penetrating agent and 0.5 to 2 parts of curing agent. According to the water-based adhesive, the external cross-linking agent, the wetting agent, the penetrating agent and the curing agent are added into the water-based polyurethane glue for the shoes, and a reticular structure is formed among macromolecular chains in the water-based polyurethane glue, so that the infiltration capacity, adhesive force, coating performance and curing and drying performance of the water-based polyurethane glue are improved, the defects of low initial viscosity, low drying speed, poor water tolerance and solvent resistance of a latex film, low glossiness of the latex film and poor comprehensive performance of a coating film in the conventional water-based adhesive are overcome, and the initial viscosity, coating performance, drying performance and bonding performance of the coating film in the water-based adhesive for the shoes substantially. The water-based adhesive can be comparable to solvent-base polyurethane resin.
Description
Technical field
The present invention relates to a kind of adhesive for shoes, particularly a kind of aqueous adhesive for shoes that existing aqueous polyurethane glue is improved.
Background technology
95% what all use is chloroprene rubber adhesive agent in China's shoemaking industry, uses aqueous polyurethane enterprise fewer, but because the good cold bonding of chloroprene rubber adhesive agent tack, low price, use habit etc. are its advantages, valencys neoprene latex is at a low price selected by many enterprises.But, the not plasticizer-resistant infiltration of its performance, poor to novel footwear such as soft pvc, TPR, PU leather with material adhesive property; The benzene class that must use in addition is a noxious solvent; This is fatal weakness, and the serious harm employee's is healthy, the requirement of incompatibility shoemaking industry development.China is shoemaking big country, annual many hundred million couples of the 1O0 that produces.Adhesive for shoes experienced one by low side to high-end, by the evolution of non-environmental protection to the environmental protection direction: at first be common chloroprene rubber adhesive agent (the 1st generation); Then for graft modification neoprene latex and solvent borne polyurethane tackiness agent (the 2nd generation), then with methylacrylic acid modification " no triphen " chloroprene rubber adhesive agent, graft modification chloroprene rubber adhesive agent and urethane (PU) tackiness agent (the 3rd generation).Although the adhesive for shoes pollution problem that solved the benzene class of the 3rd generation can't solve organism volatilization (V0C) at all.Get into the 2O nineties in century, European and American countries has been worked out strict organism volatilization standard, impels the environment-friendly type adhesive for shoes appearance of the 4th generation, is mainly aqueous adhesive.The water-based glue paste is main with aqueous polyurethane mainly; Aqueous polyurethane is by West German P. Schlack successfully preparation first in 1943; Polyaminoester emulsion in 1967 is realized industriallization first and is come out at American market; Bayer company in 1972 takes the lead in aqueous emulsion of polyurethane is used as hide finishes, and aqueous polyurethane begins to become important goods.Though aqueous polyurethane history is not long, because nontoxic, nonflammable, pollution-free, energy-conservation, safe and reliable and difficult the scratch by advantages such as coating surfaces that itself had, its development is very fast.But water-based glue paste WPU tackiness agent commonly used exists usually, and tack is little, drying rate slow, the water-fast and poor solvent resistance of latex film, glossiness are lower, the shortcoming that the over-all properties of filming is relatively poor.
Summary of the invention
In view of the foregoing; The present invention is directed to existing aqueous polyurethane glue improves; A kind of aqueous adhesive for shoes is provided, has overcome that the tack that common aqueous polyurethane glue paste exists is little, drying rate slow, the water-fast and poor solvent resistance of latex film, glossiness be lower, the defective that the over-all properties of filming is relatively poor; To reach the tack of filming, coating, the drying property that increases substantially footwear use polyurethane adhesive, the purpose of cementability.
In order to achieve the above object, the present invention has adopted following technical scheme:
A kind of aqueous adhesive for shoes, it is composed of the following components to count this tackiness agent by weight ratio:
Aqueous polyurethane glue 70-95 part
Outside cross-linking agent 3-8 part
Wetting agent 0.1-0.5 part
Permeate agent 0.1-0.5 part
Solidifying agent 0.5-2 part.
Optimum, it is composed of the following components to count this tackiness agent by weight ratio:
85 parts in aqueous polyurethane glue
5 parts of outside cross-linking agents
0.3 part of wetting agent
0.3 part of permeate agent
1.5 parts in solidifying agent.
Above-mentioned aqueous polyurethane glue is domestic shoe industry aqueous polyurethane glue commonly used.
Above-mentioned outside cross-linking agent is selected from water dispersible polyisocyanate, aminoresin, polyamine, Al (OH)
3, Ca (OH)
2Or Mg (OOCCH
3)
2
Above-mentioned aminoresin is at least a in urea-formaldehyde resin, terpolycyantoamino-formaldehyde resin, the polymeric amide epoxy polyamine chloropropane.
Above-mentioned polyamine is 3,3'-two chloro-4, and 4'-diaminodiphenyl-methane, Ucar 35 be two-at least a in (4,4 ' one diamino-) benzoic ether.
Above-mentioned wetting agent is at least a in Witco 1298 Soft Acid, the X 2073.
Above-mentioned permeate agent is at least a in aerosol-OT salt, the AEO.
Above-mentioned solidifying agent is at least a in hydrophilic aliphatics-polymeric polyisocyanate, the nano level polynite.
A kind of preparation method of aqueous adhesive for shoes is: in aqueous polyurethane glue, add outside cross-linking agent earlier; After reacting one hour under 50 ℃ of temperature; Add wetting agent, permeate agent, solidifying agent successively and evenly stir, till aqueous polyurethane glue becomes the colloidal sol shape, get final product.
The present invention is through adding outside cross-linking agent in footwear use polyurethane adhesive; Make to form reticulated structure (introducing of linking agent make between the polyurethane macromolecular chain to introduce chemical bond form reticulated structure) between the macromolecular chain in the water-based polyurethane adhesive, have excellent water-fast, anti-solvent and mechanical property; Through adding the mode of wetting agent, permeate agent, solidifying agent; Improve its wetting capacity, sticking power, coating and solidify drying property; Overcome that the tack that common water-based glue paste exists is little, drying rate slow, the water-fast and poor solvent resistance of latex film, glossiness be lower; The defective that the over-all properties of filming is relatively poor can increase substantially the tack of filming, coating, the drying property of footwear use polyurethane adhesive, cementability.Can compare favourably with the performance of solvent type polyurethane resin.
