There is also a mixed cloth-scraping slurry obtained by organically combining the three above materials. The gasoline cloth scraping adhesive has the advantages of good bonding effect, excellent elasticity and hand feeling and convenience for subsequent processing, but has the defects of complex manufacturing process, large noise and dust pollution, very high cloth scraping cost (because of large consumption and high material cost), and the most important reason is that the condition of electrostatic ignition during cloth scraping frequently occurs because of the existence of gasoline molecules. The natural latex (or synthetic latex) cloth scraping slurry, the chemical cloth scraping slurry and the starch cloth scraping slurry are all aqueous mucilage and have the advantages of less preparation procedures and no fire hazard, wherein the natural latex cloth scraping slurry is generally prepared by thickening latex by using a thickening agent and adding part of emulsified filler, and has the defects of poor stability of the latex slurry and easy precipitation and delamination of the filler; because the natural latex has large molecular weight, the coating has poor elasticity and poor smooth hand feeling, the sewing process, especially the stitching of the insole fabric, is greatly influenced, and the operation of the upper shoe last is influenced due to the insufficient elasticity of the insole fabric; the starch cloth scraping slurry is prepared by taking starch as a main material and adding a small amount of natural latex or polyvinyl alcohol and the like, has low cost, but has the defects of easy deterioration and mildewing, poor water washing resistance of products and the like.

Detailed Description

The environment-friendly cloth scraping adhesive for shoes comprises the following raw materials in parts by weight: 100 parts of soft water, 30-120 parts of polyacrylate modified rubber powder, 0-15 parts of polyvinyl acetate emulsion, 5-30 parts of natural latex premix and 5-30 parts of styrene-butadiene latex; the polyacrylate modified rubber powder is a product of Shijiazhuang Jintian Toenmao Limited, the polyacrylate belongs to an ester product, and the polyacrylate has very mild fragrance, so that the irritant ammonia odor can be basically covered even after the ammonia-containing natural latex is added, the operating environment of workers is greatly improved, and the operation workers are advocated and appreciated. Due to the lubricating property of the ester group, the coating film after the slurry scraping has very smooth hand feeling and ductility, is very beneficial to sewing operation and lasting operation of uppers and middle base fabrics, and overcomes the defects of a natural rubber film. The polyacrylate is composed of 8.5% of ethyl methacrylate, 11% of methyl acrylate, 19% of methacrylic acid modified monomer, 6% of sodium dodecyl sulfate (SDS-Fus L agent), 3.6% of potassium persulfate, 1% of dodecyl mercaptan and the like, hard monomers of the acrylate copolymer are crushed into 1-2 ram particles, the particles are poured into 20-30% pre-emulsification monomer equipment, a mixed solution of deionized water, acrylic acid and sodium dodecyl sulfate is added, stirring is carried out for 3-4 h at the rotating speed of 200-300 r/min, the temperature is controlled to be 30-40 ℃, the higher the grinding fineness is, the better the emulsification effect is, and then sol (the particle size is 25-30 nm) is obtained. Standing for 6 hours after slurrying. In the equipment for emulsifying and forming the slurry, the rotating speed of the equipment is controlled at 100-150r/min, a method of dripping potassium persulfate (KPS initiator) and dodecyl mercaptan (chain transfer agent) is adopted, the dripping time is 2-3h, and the reaction temperature is maintained at 75-85 ℃. And after the dropwise addition is finished, adding a little initiator, and continuing to react for 1-2 h. The dispersing medium water accounts for about 65 percent of the total amount of the monomers, and when the temperature of the polymer is reduced to room temperature, the pH value is adjusted to 9, and the final reaction product is obtained. It is also possible to add 0.5 to 1 part of 6-di-tert-butyl-p-cresol, 0.1 to 0.3 part of thiodipropionate, 0.01 to 0.03 part of polyacrylamide, 0.5 to 1 part of 2,4, 6-tris (2 '-hydroxy-4' -n-butoxyphenyl) -1, 3, 5, triazine, 0.1 to 0.3 part of 6-ethoxy-2, 2, 4-trimethyl-1, 2-dihydroquinoline. The polyacrylate emulsion in the polyacrylic acid modified glue is prepared by dehydration and surface modification, and the introduction of the hydrophilic group can lead the glue powder to be quickly dissolved and swelled in cold water within 5 minutes, thereby being much more convenient and quicker than the starch needing to be dissolved by steam. According to different requirements of the stiffness, elasticity or coating performance of the cloth scraping adhesive cement, the selected molecular weight of the polymerized molecular weight of the polyacrylate is 1-3000 ten thousand, along with the reduction of the molecular weight, the more water is needed for the rubber powder to reach saturated swelling, the total solid content can be greatly increased, but the cost can be correspondingly increased; under the condition of the same solid content, the larger the molecular weight is, the larger the emulsion viscosity is, but the lower the sizing amount of the scraped cloth is, so that the porous middle sole cloth is not good, and the middle sole adhesive cement is penetrated in the forming process due to the poor eyelet plugging besides the poor stiffness; the modified rubber powder with large molecular weight is prepared by mixing the following components in percentage by weight of 1: 5, the viscosity of the fabric can be higher when the fabric is dissolved in water, the manufacturing cost is lower, and the fabric is more suitable for fabrics (such as various surfaces, linings and the like) with more compact woven fabrics and less sizing requirement; for the cloth with more holes, larger holes or more sizing amount and high stiffness requirement (such as base cloth in honeycomb structure, network silk cloth and the like), low molecular weight modified rubber powder is considered, and the ratio of the rubber powder to the base cloth can be 1: 1, dissolving in water, thereby increasing the total solid content of the mucilage, and increasing the sizing amount, the pore plugging property and the stiffness; the purpose of adding a small amount of natural latex is to increase the self-adhesion of a coating film (burr is not easy to generate when punching is carried out) or increase the adhesive property between the middle base cloth and the sponge rubber; the stiffness of the cloth is increased, and the like. Since the direct addition of natural latex to polyacrylate emulsions leads to gelation, the latex must be pretreated first, i.e., by adding various stabilizers and increasing the pH, and added at a low rate to achieve stable mixing. With the increase of the proportion of the natural latex, the cost of the mucilage is increased, the coating film forming performance of the cloth is good, the holes of the cloth are easy to block, the stiffness of the cloth is good, but the extensibility is weakened, the smoothness of hand touch is reduced, and the sewing operation of stitching and attaching a middle base cloth is not facilitated, so a designer should comprehensively consider the materials, the process and the like of the used cloth, and a pulp scraping formula which is most suitable for the cloth is worked out; the polyvinyl acetate emulsion is a formula option, is commonly called as 'milk white glue', is generally used as an adhesive for wood, paper and the like in the industrial industry, and because the rigidity of molecular chains of the polyvinyl acetate emulsion is stronger than that of natural rubber molecular chains, a coating film is relatively hard, and when the required pulp scraping cloth is required to be good in stiffness, a small amount of the emulsion can be considered to be added. With the increase of the mixing amount of the polyvinyl acetate emulsion, the stiffness of the pulp scraping cloth is gradually increased, the extensibility is reduced, and the smooth hand feeling is reduced; borax is a high-quality and low-price bactericide, and is added to better prevent the pulp scraping cloth from being affected with moisture, protein deterioration and the like in the storage process; the colorant is used for enabling an operator to better observe whether the mucilage is uniformly prepared or not and whether scraping leakage or scraping excessive scraping occurs or not during scraping the mucilage; the vulcanizing agent is also an option of formula, and when the adhesive force between the pulp scraping cloth and the contacted rubber component is required, a certain vulcanizing agent can be properly added according to the condition of a factory.

In the embodiment, the natural latex premix comprises the following raw materials in parts by weight: 100 parts of natural latex, 100 parts of soft water, 10-15 parts of 20% sodium hydroxide solution, 0.1-0.5 part of borax, 0.3-0.5 part of a stabilizer H5; the stabilizer H is a product of Dongchang chemical Co., Ltd, Yixing, Jiangsu, and the compounding agents are added into the natural latex in sequence according to the above list.

In this embodiment, the cloth scraping adhesive cement comprises the following raw materials in parts by weight: 100 parts of soft water, 80 parts of polyacrylate modified rubber powder, 8 parts of polyvinyl acetate emulsion, 20 parts of natural latex premix and 20 parts of styrene-butadiene latex;

in the embodiment, the molecular weight of the polyacrylate modified rubber powder is 5 ten thousand, so that the total solid content of the rubber paste is increased, and the aim of increasing the hole plugging property of the mesh fabric is fulfilled; in order to increase the stability of the rubber cement during mixing and reduce the cost, the styrene-butadiene rubber latex is adopted to replace the natural rubber latex.

in the embodiment, in the step b, under the condition of slow stirring, firstly adding the polyvinyl acetate emulsion slowly and uniformly, then adding the styrene-butadiene latex, and finally adding the natural latex premix;

in this embodiment, the rotation speed of the slow stirring is 500 rpm or less.

The dissolution requirement of polyacrylate modified rubber powder is high, high-speed stirring is required to ensure that the rubber powder is sheared into powder to achieve the purpose of quick dissolution just after being added into water, if the rubber powder on a stirring shaft or a container wall is agglomerated because the rubber powder cannot be quickly dissolved, the stirring shaft or the container wall is immediately stopped to clean the rubber powder, the stirring shaft is stirred again for dissolution, and otherwise, the agglomerated materials are not easily mixed into the water any more. As mentioned above, the natural latex is selected to be premixed, and can be added into the modified rubber powder emulsion after the stability of the latex is improved; the addition of the natural latex premix and the polyvinyl acetate emulsion needs to be slowly and uniformly added to prevent the emulsion from coagulating.
