(Industrial Application Field) The present invention relates to a method for adhering textile materials and soft polyvinyl chloride, and more specifically, to strengthen the adhesion between textile materials and soft polyvinyl chloride, and to bond the textile materials and soft polyvinyl chloride under high temperature and high humidity conditions. This invention relates to an adhesive method that maintains adhesive strength. (Prior art) Conventionally, adhesive compositions mainly composed of polyester or polyester polyurethane having hydroxyl groups in the molecular chain have been used to bond polyester fibers and polyvinyl chloride. Polyisocyanates have been added.
If this adhesive composition is used, after bonding, the temperature will exceed 100℃.
Even at such high temperatures, we were able to obtain excellent adhesive strength. However, in this method, firstly, polyisocyanate reacts at room temperature, so it is not possible to add polyisocyanate in advance to prepare a large amount of adhesive composition, and secondly, because polyisocyanate is highly reactive, This method has drawbacks such as the need to adhere immediately after applying the adhesive composition to one of the adherends. (Problems to be Solved by the Invention) The present invention aims to improve the above-mentioned problems, and not only improves the adhesive strength between the fiber material and soft polyvinyl chloride, but also improves the adhesive strength in high temperature and high humidity environments. The object of the present invention is to provide an adhesive method that can be maintained even under conditions of low temperatures and can be maintained for a long time. (Means for Solving the Problems) That is, the present invention is characterized in that a fiber material is immersed in a pretreatment liquid made by adding a polyisocyanate compound to a vinyl chloride sol, and then heat-treated. A film is formed on the above-mentioned fiber material by gelling a part of the pre-treatment liquid, and then immersed in a polyvinyl chloride sol solution, which is a post-treatment liquid, and then heat-treated to gel a part of the post-treatment liquid. The present invention provides a method for bonding a fiber material and soft polyvinyl chloride by drying the fiber material in a compressed state to obtain an adhesive-treated fiber material, and applying pressure and heat to the fiber material and soft polyvinyl chloride to bond them together. In the method of the present invention, a partially gelled film of polyvinyl chloride (hereinafter referred to as PVC) is formed around the adhesive-treated fiber material, which has good compatibility with the soft polyvinyl chloride that is the adherend. This increases the adhesion between the adherends, and the isocyanate compound added to the pretreatment liquid increases the adhesion between the pretreatment liquid and the fiber material or between the pretreatment liquid and the posttreatment liquid. Furthermore, since a highly reactive polyisocyanate compound is not present in the outermost layer of the fiber material, the adhesive-treated fiber can be stored for a long period of time. The pretreatment liquid used in the present invention is a PVC sol added with an isocyanate compound, and the polyisocyanate compound may be any polyisocyanate compound as long as it has two or more isocyanate groups in one molecule, such as These include toluene diisocyanate, xylene diisocyanate, naphthalene diisocyanate, hexane diisocyanate, isophorone diisocyanate, diphenylmethane diisocyanate, polymethylene polyphenylene diisocyanate, and the like. The polyisocyanate compound is usually added in an amount of 0.5 to 20% by weight in the PVC sol. In this case, if the amount of polyisocyanate compound added is 0.5% by weight or less, the fiber material and post-treatment
Adhesion with PVC sol is poor, and if it exceeds 20% by weight, gelation of PVC sol progresses too much, resulting in
Contact with the sol deteriorates, resulting in poor adhesion to the adherend, soft polyvinyl chloride.
Preferably it is 0.6 to 12% by weight. In addition, the drying conditions for the PVC sol used for pre-treatment and post-treatment are as follows: 1 to 10 minutes at 80 to 150°C is required; at 80°C for 1 minute or at 150°C for 10 minutes, the PVC sol may partially gel. It is difficult to keep it in a semi-gel state, preferably in a semi-gel state, resulting in poor adhesion with flexible polyvinyl chloride. In the present invention, it is necessary to apply the PVC sol to the fiber material in a partially gelled state during pre-treatment and post-treatment. When heated and pressurized at 25 kg/cm 2 , the partially gelled film on the fiber material completely gels, thereby strengthening the adhesion between the fiber material and the soft polyvinyl chloride. The PVC sol used in the above pre-treatment and post-treatment is the same, and may be plastisol or organosol, and is not particularly limited. The fiber materials used in the present invention are made of polyester fibers, aliphatic polyamides, aromatic polyamides, and glass fibers, and are in the form of woven fabrics, knitted fabrics, cords, films, etc. The soft polyvinyl chloride used in the present invention is a known one having a degree of polymerization of 500 to 5000 and containing 60 to 120 parts by weight of a polyester plasticizer. Next, examples of the present invention will be described. Example 1 First, a plain woven fabric (1500D/1×600D/1/61×70) made of polyester fibers was immersed in the pretreatment liquids (A, B) shown in Table 1 and dried at 140° C. for 2 minutes. Next, the fiber material immersed in the blended solution A was treated with the blended solution (C) in Table 2, and the fiber material immersed in the blended solution B was treated with the post-treatment solutions (D, E, F,) in Table 2 using a doctor knife. The coating was applied uniformly at a rate of 50 g/m 2 using a 50 g/m 2 coating, and dried at 120° C. for 5 minutes. A soft polyvinyl chloride sheet (polymerization degree 2500, containing 85 parts by weight of polyester plasticizer, Ba stabilizer, etc.
20 kg / 0.6 mm thick sheet with JIS-A hardness of 70
It was pressed for 5 seconds at a pressure of cm 2 . In this case, Table 3 shows the standing time after the post-treatment liquid was applied and dried until it was adhered to the soft polyvinyl chloride and the time until the peeling force was measured after the adhesion was completed. The peeling force was measured according to the conditions shown in Table 3 above.
The measurement temperature was 100°C and the peeling speed was 50 mm/min.
The results are shown in Table 4.

After drying at 140° C. for 2 minutes, post-treatment liquid C shown in Table 2 was applied, dried, and pressed in the same manner as in Example 1. The peel force results at 100°C are shown in Table 6.

In addition, the highly reactive polyisocyanate compound contained in the pre-treatment liquid improves the adhesion between the fiber material and the pre-treatment liquid, and between the pre-treatment liquid and the post-treatment liquid, further improving the adhesive strength. and,
Even if the adhesive-treated fiber material is left in a high-temperature, high-humidity environment for several days, it will not be affected in any way because the polyisocyanate compound is completely surrounded by the post-treatment liquid, and it will remain as soft polyvinyl chloride. It has excellent effects such as almost no decrease in adhesive strength.
