In the step 1, the dosages of the components are calculated according to mole fraction, namely, 1 part of citric acid, 1-2 parts of polyethylene glycol, 0.005-0.05 part of p-toluenesulfonic acid, 2 parts of toluene, 3-3.5 parts of absolute ethyl alcohol, 2.4-3 parts of thionyl chloride and 2-2.2 parts of aminopropyl triethoxysilane.
In the step 2, the preparation method of the polyurethane hot melt adhesive specifically comprises the steps of mixing polyethylene glycol, 1, 4-butanediol, a modified cross-linking agent and an antioxidant, heating and stirring at 110-140 ℃, uniformly mixing, vacuum drying and dehydrating for 2.5 hours, cooling to 65-75 ℃, adding isophorone diisocyanate and stannous octoate, reacting for 20-30 minutes, discharging, sealing and packaging, and curing for 6-8 hours in a 70-90 ℃ oven.

In the present invention, grafting of polyethylene glycol and aminopropyl triethoxysilane is carried out by reacting an alcoholic hydroxyl group with a carboxyl group on citric acid, and thus the amount of the reactants and the reaction sequence are limited. Experiments show that the reaction activity of polyethylene glycol and citric acid is higher, and the reaction is controllable, so that the polyethylene glycol can be fully reacted by adjusting the mol ratio (1-2) of the reactant polyethylene glycol to the citric acid to be 1, and meanwhile, the citric acid can be used for grafting aminopropyl triethoxysilane while remaining excessive unreacted carboxyl. When the reaction sequence of polyethylene glycol and aminopropyl triethoxysilane cannot be changed, the reaction needs to be carried out in an ethanol environment, namely the ethanol is excessive, if aminopropyl triethoxysilane is grafted with citric acid, three carboxyl groups of the citric acid can be completely reacted, so that the reaction with the polyethylene glycol cannot be carried out, and the obtained polyurethane hot melt adhesive has no three-dimensional network structure and has poor bonding effect.

Cutting the adhesive lining cloth in examples 1-6 and comparative examples 1-3, wherein the size of the sample is 200mm multiplied by 70mm, cutting terylene fabric (from a special fabrics strength supplier, product number HY 2189) with the size of 200mm multiplied by 80mm as a standard fabric, placing thin tissue paper between the adhesive lining cloth sample and the standard fabric, pressing and cooling to obtain a combined sample, and preparing 5 samples for each group of experiments, wherein the effective adhesive area of the combined sample is 50mm multiplied by 110mm, and taking the average value as a final test result;
The initial peeling strength is obtained by using a tensile testing machine to stretch at a constant speed of 100mm/min, peeling, stopping stretching and reading after the combined fabric with the actual bonding width of 50mm is peeled for 100mm displacement, testing 5 times in each group of experiments, and taking the average value as the initial peeling strength;
the water treatment peeling strength is that the combined sample is soaked in clear water at 25 ℃ for 24 hours, taken out and dried to constant weight, and the peeling strength is tested by referring to the method and is recorded as the water treatment peeling strength;
heat treatment peel strength the combined samples were heat treated under vacuum at 200 ℃ for 12 hours, and after cooling, the peel strength was tested with reference to the above method and noted as heat treatment peel strength.

The data of examples 1-6 show that the adhesive lining cloth prepared by the invention has good water resistance and heat resistance, the peel strength is not greatly changed after water treatment and heat treatment, and meanwhile, the adhesive lining cloth prepared by the invention has excellent air permeability and comfortable wearing feeling. The data of example 1 and comparative example 1 show that the adhesive interlining prepared by adding the modified crosslinking agent has better performance, because the modified crosslinking agent contains a plurality of hydroxyl groups and can react with isocyanate to obtain the crosslinked polyurethane hot melt adhesive, thereby improving the water resistance of the adhesive interlining, and in addition, the modified crosslinking agent contains a silicon-oxygen bond, so that the polyurethane hot melt adhesive has better thermal stability. In comparative example 2, the aminopropyl triethoxysilane was directly added, and the amino group was able to react with the isocyanate group to form a urea group, so that the dispersibility in the polyurethane hot melt adhesive was good, but the initial peel strength was lower than that of example 2, indicating that the invention is superior to the conventional technical means. In comparative example 3, after the reaction sequence is changed, excessive ethanol makes citric acid fully react, and can not react with polyethylene glycol any more, so that the obtained product can not generate a crosslinking effect with polyurethane, the compatibility with polyurethane is greatly reduced, and the initial peel strength, the water resistance and the heat resistance of the finally prepared adhesive lining cloth are far lower than those of example 3.
It should be noted that the above-mentioned embodiments are merely preferred embodiments of the present invention, and the present invention is not limited thereto, but may be modified or substituted for some of the technical features thereof by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
