Description
Technical Field
The invention belongs to the technical field of EVA (ethylene-vinyl acetate) surface treatment agents, and relates to an aqueous treatment agent suitable for a high-elasticity EVA material and a preparation method thereof.
Background
The middle soles of the sports shoes on the market are mostly formed by foaming EVA (ethylene-vinyl acetate copolymer) and a blend thereof, wherein the EVA is a copolymer synthesized by a nonpolar ethylene monomer and a polar vinyl acetate monomer through various polymerization modes such as bulk polymerization, solution polymerization, emulsion polymerization and the like, and the polarity of an EVA material is weak because the vinyl in the EVA molecule is a nonpolar group, so that the water-based polyurethane adhesive widely used in the shoe industry is not good in adhesion, and the EVA material which is not subjected to surface treatment is difficult to achieve ideal adhesive strength. In order to improve the adhesion of the adhesive to EVA, the EVA must be surface pre-treated. However, more than 80% of the surface treating agents on the market are solvent-type products, the existence of volatile organic solvents can cause environmental pollution, the health of operators can be endangered, and the risks of fire and explosion exist. The aqueous EVA treating agent is still in the development stage, and the solvent water is used for simply replacing an organic solvent to prepare the EVA treating agent, so that the problems of reduced polarity of the treating agent, reduced applicability of the treating agent to EVA substrates, mismatching of the treating agent and an adhesive, reduced bonding strength and peeling strength of the treating agent and the like occur, and in addition, the peeling strength in the initial drying stage is low, so that the requirement on efficiency in actual production cannot be met.
Castor oil is low in price, can carry out a plurality of chemical reactions through hydroxyl groups, double bonds and ester bonds, and is a renewable resource with great development prospect. The castor oil is mainly obtained by squeezing or solvent extracting castor seeds, the main component of the castor oil is fatty acid triglyceride, each fatty acid carbon chain consists of 18 carbon atoms, ester groups, unsaturated carbon-carbon double bonds and hydroxyl groups exist on the carbon chain, and the active groups provide possibility for chemical modification of the castor oil, and the addition of the castor oil can enable the polymer to form a compact polymer structure during reaction.
Cellulose molecules have a plurality of research surfaces, and the cellulose molecules are introduced into a composite material, so that the mechanical strength of a system can be greatly improved, and a coating film formed by a treating agent can be prevented from being stripped easily, but abundant hydroxyl groups in the cellulose molecules enable the cellulose molecules to have hydrophilicity, so that moisture in air is easily adsorbed to cause collapse of a pore structure, and the application of the cellulose molecules in the field of adhesive treating agents is limited.
Disclosure of Invention
The invention aims to provide a water-based treating agent suitable for a high-elasticity EVA material and a preparation method thereof, wherein the water-based treating agent has good compatibility with an EVA base material and a water-based polyurethane adhesive, and a formed coating film has higher mechanical strength and bonding property; the preparation method of the water-based treating agent has the characteristics of simple modification process and mild reaction conditions.
The aim of the invention can be achieved by the following technical scheme:
the water-based treating agent suitable for the high-elasticity EVA material comprises the following components in parts by weight:
the preparation method of the aqueous treating agent comprises the following steps:
s1, mixing castor oil, mercapto alcohol and a photoinitiator, reacting for 2 hours at room temperature under the irradiation of an ultraviolet lamp, diluting a product obtained by the reaction with chloroform, washing with saturated sodium chloride and distilled water for 3 times, drying with anhydrous magnesium sulfate, and evaporating a solvent to obtain the polyhydroxy castor oil;
s2, preparing a dopamine hydrochloride solution, regulating the pH value to 9-10, adding a nano cellulose aqueous dispersion, separating a water phase, adding acetone, stirring for 10-30min, standing, and stirring at a speed of 100-200rpm to obtain a modified nano cellulose acetone solution;
s3, adding modified nano cellulose acetone solution into the polyhydroxy castor oil prepared in the step S1, finally, centrifuging, freeze-drying, sequentially adding deionized water and vegetable oil, uniformly mixing, and performing ultrasonic dispersion under a cell pulverizer for 5min to obtain modified emulsion;
s4, adding the oligomer resin into the modified emulsion to adjust the hardness, stirring uniformly, adding the aqueous auxiliary agent under the stirring condition, dispersing uniformly, and filtering to obtain the aqueous treating agent.
