(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 adhesion method that can be maintained even under conditions of low temperature and can be maintained for a long time. (Means for Solving the Problems) That is, the present invention is characterized in that the fiber material is a polyester having a group having active hydrogen in the molecular chain, a polyester polyurethane obtained by chain-extending the polyester with a polyisocyanate, or After immersing in a pre-treatment liquid made by adding a polyisocyanate compound to a compound selected from polycarbonate-based polyester polyurethane, and then immersing it in a post-treatment liquid consisting of a polyvinyl chloride sol solution, some of the post-treatment liquid is gelled. The present invention provides a method of bonding a fiber material and soft polyvinyl chloride by drying the fiber material to a softened state to obtain an adhesive-treated fiber material, and applying pressure and heat to the soft polyvinyl chloride to bond the two 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 polyester polyurethane having a group having active hydrogen in its molecular chain or a polyester polyurethane obtained by chain-extending the polyester with a polyisocyanate, and a polyisocyanate compound is added to the polyester polyurethane. may be any compound having two or more isocyanate groups in one molecule, such as toluene diisocyanate, xylene diisocyanate, naphthalene diisocyanate, hexane diisocyanate, isophorone diisocyanate, diphenylmethane diisocyanate, and polymethylene polyphenylene diisocyanate. etc. It is usually added in an amount of 0.5 to 20% by weight in the above polyester or polyester polyurethane. In this case, the amount of polyisocyanate compound added is
Below 0.5% by weight, fiber materials and post-processing PVC
Adhesion with the sol is poor, and if it exceeds 20% by weight, the crosslinking of the polyester or polyester polyurethane proceeds too much, resulting in poor wetting with the PVC sol in the post-treatment, and as a result, the adhesion with the soft polyvinyl chloride, which is the adherend, becomes poor. It is preferable to use 0.6 to 12% by weight because the adhesion of the fiber material decreases and the treated fiber material becomes hard, making it impossible to use it for small pulley diameters and poor bending fatigue resistance. good. In addition, the drying conditions and post-treatment of a polyester having a group having active hydrogen in its molecular chain, a polyester polyurethane obtained by chain-extending the polyester with a polyisocyanate, or a pre-treatment liquid made by adding a polyisocyanate compound to a polycarbonate-based polyester polyurethane. The drying conditions for the PVC sol used are 80 to 150°C for 1 to 10 minutes; at 80°C for 1 minute or at 150°C for 10 minutes, crosslinking of the polyester, polyester polyurethane, or polycarbonate polyurethane will proceed too much. Alternatively, it is difficult to maintain the PVC sol in a partially gelled state, preferably a semi-gelled state, resulting in poor adhesion to soft polyvinyl chloride. In the present invention, it is necessary to attach the PVC sol to the fiber material in a partially gelled state in the post-processing, and in this state, it is brought into close contact with the adherend, which is soft polyvinyl chloride, and the weight is 15 to 25 kg at 160 to 190°C. When heated and pressurized at /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, such as 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, embodiments 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 solution (A) shown in Table 1 and dried at 140° C. for 2 minutes. Next, the formulations (B, C, DE) shown in Table 2 were uniformly applied using a doctor knife at a rate of 50 g/m 2 and dried at 120° C. for 5 minutes. The treated canvas thus obtained was preheated at 175°C for 5 minutes to form a soft polyvinyl chloride sheet (polymerization degree
2500, containing 85 parts by weight of polyester plasticizer, Ba stabilizer, etc., hardness JIS-A 70, 0.6 mm thick sheet) at a pressure of 20 kg/cm 2 for 5 seconds. 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.

The highly compatible and highly reactive polyisocyanate compound contained in the pre-treatment liquid provides good adhesion between the fiber material and the film of the pre-treatment liquid, as well as the film formed from the pre-treatment liquid and the post-treatment liquid. Furthermore, when the adhesive-treated fiber material is heated and pressurized with soft polyvinyl chloride, the peeled or blocked isocyanate compound in the pre-treatment liquid adhering to the fiber material is removed. reacts to further increase the bonding strength between the two adherends, and even if the adhesive-treated fiber material is left in a high-temperature, high-humidity environment for several days, the polyisocyanate compound contained in the pretreatment liquid Because it is completely surrounded by the post-treatment liquid, it is almost unaffected by moisture, so it can be stored for a long time, and it has excellent effects such as almost no decrease in adhesive strength with soft polyvinyl chloride. have.
