Abstract
The present invention relates to a colorless transparent adhesive for hot-cured cloth covered rubber shoes, and a preparation method thereof, which belongs to the preparation technique of adhesives. The colorless transparent adhesive is prepared by chemically grafting synthetic rubber, natural rubber and an acrylic ester monomer into a high polymer and mixing the high polymer with an antioxidant and an organic solvent. The colorless transparent adhesive has the characteristics that the colorless transparent adhesive is colorless, transparent and hidden; the colorless transparent adhesive is used for bonding edge strips of cloth covered rubber shoes; after the shoes are cured thermally at 130 DEG C, adhesive traces are not reserved on vamps; after the shoes are packed and stored for more than one year, no yellowing phenomenon appears. The colorless transparent adhesive replacing traditional latex slurry and gasoline adhesive slurry can be used for preparing high-grade rubber shoes with the advantages of high bonding strength and no adhesive slurry pollution on the vamps. The colorless transparent adhesive has the advantages of large economic benefit and large social benefit.
Description
The invention belongs to the technology of preparing of rubber overshoes tackiness agent, particularly the colourless transparent invisible adhesive manufacturing technology.
The hot sulfurization canvas rubber shoe is the big kind in the present footwear of China.Also be a very big footwear kind of China's export volume, in existing traditional processing technology, be to use latex slurry or gasoline rubber cement to coat bond site, then foxing is fitted, make product shoes through pressurization and hot sulfurization again.For guaranteeing the foxing bond strength, prevent that from the limit rubber cement coating width often needs to exceed the foxing width, this will make and stay the tangible rubber cement vestige of a circle on vamp, influence the rubber overshoes outward appearance, reduction rubber overshoes rank class, and the expansion of selling market is interrupted.During the last ten years, in order to address these problems, many producers and research unit have all carried out research work, all make slow progress, present adopted method has: the pasting of 1. ruling, and this method must carefully be done in Seiko, labour productivity is too low, production cost increases, but also is difficult to guarantee bonding quality, and this is a kind of unavoidable method really; 2. exempt from the slurry method, be that vamp exempts to be coated with rubber cement, and on foxing coating rubber cement or applying adhesive layer, this method makes process complications, and adhesive layer also is difficult to make vamp to reach good moisture state, on suitability for industrialized production, be difficult to guarantee bonding quality, and foxing back edge material can not re-use, and causes bigger waste and loss, increased cost; 3. adopt vamp and foxing coating technique respectively, produce the pollution-free rubber overshoes of vamp, because technology is many one foxing coating process, and the operation that increases be owing to will make the foxing upset, so during gluing, will pollute isolation base fabric or work top, it is many to have made complex process, cost increases, so, in fact all do not tackle the problem at its root.
Purpose of the present invention is exactly in order fundamentally to solve problems such as the pollution vamp that exists in the existing hot sulfurization canvas rubber shoe manufacturing technology, complex process, and the novel colourless transparent invisible glue stain that does not pollute vamp after a kind of sulfuration is provided.
Main points of the present invention are: containing percentage of grafting is 10～50% cis-1,4-polybutadiene rubber or chloroprene rubber, the synthetic rubber of butyl type rubber and methacrylic acid glycol ester or methyl methacrylate, the acrylic ester monomer of butyl methacrylate class becomes the graft copolymer solution A through chemical graft, be that 15～30% natural rubber becomes the graft copolymer solution B with vinylformic acid quinones monomer through chemical graft by containing percentage of grafting again, and then being 10～20% than the graft copolymer solution A of calculating by weight, the graft copolymer solution B is 5～15%, antioxidant 264 (2,6 ditertiary butyl p cresol) is 1～3%, toluene, gasoline class organic solvent 78～88% mixes, stir and be prepared into colourless transparent invisible adhesive.
Advantage of the present invention and effect are: the colourless transparent invisible adhesive of using the inventive method to make replaces the latex slurry that uses in the prior art or gasoline rubber cement and coats vamp and paste the position of foxing and bonding with foxing, adhesion strength 〉=the 2.2KN/m of foxing and upper of a shoe, reach national GB318-83 standard, after 130 ℃ of hot sulfurizations, vamp non-adhesive vestige, package storage did not still have the yellowing phenomenon in 1 year, so it is pollution-free that tackiness agent of the present invention can be made vamp, the high quality canvas rubber shoe of appearance looks elegant, thereby improved the rank class of footwear, simultaneously, use tackiness agent of the present invention, can only coat on the vamp, so be suitable for existing traditional technology operation.Owing to needn't worry rubber cement coating scope, its operation is also simpler than the traditional technology operation, therefore, also can improve speed, reduce cost, data by present investigation grasp, export the canvas rubber shoe of the free of contamination high-level class of this vamp, the comparable price of having been polluted the rubber overshoes of vamp by other glue stains of its order price improves 0.2～0.3 dollar/pair, amount to Renminbi, improve 1～1.5 yuan/pair, by 1,000,000 pairs of calculating of annual outlet, can rise in value 100～1,500,000 yuan, can be country and earn a large amount of foreign exchanges more, obviously, the present invention has very big economic benefit and social benefit.
The inventor once did a large amount of successful implementation examples, one of them is to be that synthetic rubber-cis-1,4-polybutadiene rubber of about 30% becomes the graft copolymer solution A with acrylic ester monomer-methacrylic acid glycol ester through chemical graft containing percentage of grafting, containing percentage of grafting is that about 25% natural rubber becomes the graft copolymer solution B with acrylic ester monomer-methyl methacrylate through chemical graft, get 15 kilograms of above-mentioned graft copolymer solution A then, the graft copolymer solution B is mixed for 10 kilograms, add 80 kilograms of organic solvent toluene again, anti-aging agent mixes and stirs for (264) 2 kilograms, promptly make colourless transparent invisible adhesive of the present invention, this tackiness agent is coated the position that white canvas vamp prepares to paste foxing with hairbrush, after hanging 1～2 minute, foxing is sticked on the vamp, again on pressing machine with the exert pressure of 0.29MPa, make foxing and vamp close adhesion, under 130 ℃ of temperature, carry out hot sulfurization then, promptly can be made into the canvas rubber shoe that no rubber cement pollutes.
