Abstract
The invention brings forward an adhesive for shoemaking. The adhesive provided by the invention is prepared by the following processes: preparation of a polyvinyl acetate glue solution, preparation of a polyethoxymethane glue solution, preparation of leather powder, preparation of phyllite powder and preparation of the adhesive. The adhesive for shoemaking has water resistance and toughening performance. Shoe seam bonded by the use of the adhesive accords with water resistance and waterproof technical indexes and has flexibility. The adhesive is applicable to be used as an adhesive for shoemaking.
Description
Technical field
What the present invention proposed is the tackiness agent of chemical field, specifically a kind of adhesive for shoemaking.
Background technology
At present, need to use white glue with vinyl tackiness agent in shoemaking process, although it is not white glue with vinyl low price, water-fast, so can not waterproof requirement be reached with the footwear that white glue with vinyl is bonding, especially can not use as the Labor protection shoes with water-proof function.
Summary of the invention
In order to make adhesiveforshoe have water resistance, the present invention proposes a kind of shoemaking tackiness agent that discharges water.This tackiness agent is made up of polyvinyl acetate emulsion and polyvinyl formal, and in glue, add leather powder.Solution adhesive for shoemaking is water-fast and the technical problem of increasing tougheness.
The present invention solves the scheme that its technical problem takes:
Preparation method:
1, Vinyl Acetate Copolymer glue is prepared: get Vinyl Acetate Copolymer 50 grams, join in 100 grams of clear water, heat under whipped state and dissolve, heating and temperature control is at 100 DEG C, maintain 5 hours, according to evaporation of water amount, supply water and reach 100 grams, make the proportionlity of Vinyl Acetate Copolymer and water reach 0.5:1, become 150 grams of Vinyl Acetate Copolymer glues;
2, prepare according to ethanol formal glue: get polyvinyl formal 50 grams, join in 100 grams of clear water, heat under whipped state and dissolve, heating and temperature control is at 100 DEG C, maintain 5 hours, according to evaporation of water amount, supply water and reach 100 grams, make the proportionlity of polyvinyl formal and water reach 0.5:1, become 150 grams of formaldehyde polyvinyl acetal liquid;
3, prepare leather powder: get pure animal's leather scrap stock 50 grams, join in the pulverizer of 10,000 turns/min, after pulverizing under zero temperature condition, obtain 200 order, 50 grams of leather powder;
4, prepare phyllite powder: by phyllite mineral 50 grams, join in masher and grind, obtain 300 order, 50 grams of phyllite powder;
5, tackiness agent is prepared: get Vinyl Acetate Copolymer glue 150 grams, formaldehyde polyvinyl acetal liquid 150 grams, 50 grams, leather powder, 50 grams, phyllite powder, urea-formaldehyde resin 10 grams, join in stirred pot, under 110 DEG C of temperature condition, be uniformly mixed 15min, each component is fully mixed, be cooled to room temperature after taking out from stirred pot, become adhesiveforshoe.
Positively effect: adhesiveforshoe of the present invention has water-fast and toughness reinforcing performance, meets water-fast and technical indicator that is waterproof with its bonding footwear seam, and has flexibility.Be suitable for applying as adhesive for shoemaking.
Embodiment
Preparation method:
1, Vinyl Acetate Copolymer glue is prepared: get Vinyl Acetate Copolymer 50 grams, join in 100 grams of clear water, heat under whipped state and dissolve, heating and temperature control is at 100 DEG C, maintain 5 hours, according to evaporation of water amount, supply water and reach 100 grams, make the proportionlity of Vinyl Acetate Copolymer and water reach 0.5:1, become 150 grams of Vinyl Acetate Copolymer glues;
2, prepare according to ethanol formal glue: get polyvinyl formal 50 grams, join in 100 grams of clear water, heat under whipped state and dissolve, heating and temperature control is at 100 DEG C, maintain 5 hours, according to evaporation of water amount, supply water and reach 100 grams, make the proportionlity of polyvinyl formal and water reach 0.5:1, become 150 grams of formaldehyde polyvinyl acetal liquid;
3, prepare leather powder: get pure animal's leather scrap stock 50 grams, join in the pulverizer of 10,000 turns/min, after pulverizing under zero temperature condition, obtain 200 order, 50 grams of leather powder;
4, prepare phyllite powder: by phyllite mineral 50 grams, join in masher and grind, obtain 300 order, 50 grams of phyllite powder;
5, tackiness agent is prepared: get Vinyl Acetate Copolymer glue 150 grams, formaldehyde polyvinyl acetal liquid 150 grams, 50 grams, leather powder, 50 grams, phyllite powder, urea-formaldehyde resin 10 grams, join in stirred pot, under 110 DEG C of temperature condition, be uniformly mixed 15min, each component is fully mixed, be cooled to room temperature after taking out from stirred pot, become adhesiveforshoe.
Application test:
The gluing place of footwear body of the bonding shoemaking of simple white glue with vinyl, made footwear footwear water resistant test machine carries out permeable test, and the average waterproof time is no more than 6 hours.Detected result is defective.
Use adhesiveforshoe of the present invention to carry out the bonding of shoemaking footwear body seam, made footwear water resistant test machine carries out permeable test, through test in 12 hours, permeable phenomenon does not occur.Detected result is qualified.
Feature:
Owing to employing Vinyl Acetate Copolymer glue and PVOH formal glue in adhesiveforshoe component simultaneously, both compounds, create colloidality enhancement, and dry rear pre-water not swollen, insoluble in water, glued membrane has elasticity, especially in component, urea-formaldehyde resin is added, more improve tackiness and water-repellancy, the leather powder added in component and phyllite powder, the cohesive strength after adhesive solidification can be prevented, and add toughness and filled-type and connectivity, so, adopt adhesiveforshoe of the present invention to make to have waterproof and watertightness and endurable firmly labor protection shoe and dailyly wear footwear.
