(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. This invention relates to an adhesive method that maintains adhesive strength. (Prior art) Conventionally, adhesive compositions mainly composed of polyester or polyester urethane, which have hydrogen groups in their molecular chains, have been used to bond polyester fibers and polyvinyl chloride. Polyisocyanates have been added to By using this adhesive composition, it was possible to obtain excellent adhesive strength even at a high temperature of 100° C. after bonding. However, this method has the disadvantage that, due to the high reactivity of polyisocyanate, it is necessary to bond immediately after applying the adhesive composition to one of the adherends. For this reason, after applying the adhesive composition to the fiber material, it is subsequently immersed in a polyvinyl chloride post-treatment solution, and further dried to a state where the post-treatment solution has partially gelled to maintain adhesive strength. It is possible to improve this point by using an adhesion method, but this method may cause unevenness on the surface of the soft polyvinyl chloride after adhering the fiber material and the soft polyvinyl chloride due to variations in the amount of the post-treatment liquid attached. This method had disadvantages such as the occurrence of (Problems to be Solved by the Invention) The present invention improves these points, 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. It is an object of the present invention to provide an adhesion method that can maintain the strength even when the fiber material is adhered to the soft polyvinyl chloride for a long period of time, and that makes the surface of the soft polyvinyl chloride smooth after adhering the fiber material and the soft polyvinyl chloride. (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 its molecular chain, a polyester polyurethane or a polycarbonate obtained by chain-extending the polyester with a polyisocyanate. After immersing in a treatment solution made by adding a polyisocyanate compound to a compound selected from polyester polyurethane, thin soft polyvinyl chloride (hereinafter referred to as adhesive layer PVC film) is then processed.
The coating layers of are laminated to form an adhesive-treated fiber material,
The present invention provides a method of adhering a fibrous material and a soft polyvinyl chloride by pressurizing and heating such a fibrous material to a thick soft polyvinyl chloride to bond them together. In the method of the present invention, a thin wall of polyvinyl chloride is formed on the surface of the adhesive-treated fiber material, which improves compatibility with the soft polyvinyl chloride that is the adherend, increasing the adhesive strength between the adherends, Furthermore, the isocyanate compound added to the treatment liquid increases the adhesive strength between the treatment liquid and the fiber material and between the treatment liquid and the adhesive layer PVC film. 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 treatment liquid used in the present invention is made by adding a polyisocyanate compound to a polyester having a group having active hydrogen in its molecular chain or a polyester polyurethane obtained by chain-extending the polyester with a polyisocyanate. , any compound having two or more isocyanate groups in one molecule may be used, 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 0.5
If it is less than 20% by weight, the adhesion between the fiber material and the adhesive layer PVC film will be poor, and if it is more than 20% by weight, the crosslinking of the polyester or polyester polyurethane will proceed too much, resulting in poor wetting with the adhesive layer PVC film. This is because the adhesion with the soft polyvinyl chloride adherend decreases, and the treated fiber material becomes hard, causing problems such as the inability to use it for small pulley diameters and poor bending fatigue properties when made into products. , preferably 0.6 to 12% by weight. In addition, the drying conditions for the treatment liquid made by adding a polyisocyanate compound to 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 a polycarbonate-based polyester polyurethane are 80 to 150% 1 to 10 minutes at 80°C or 10 minutes at 150°C will result in excessive crosslinking of the polyester, polyester polyurethane or polycarbonate polyurethane, resulting in poor adhesion to the adhesive layer PVC film. 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 flexible polyvinyl chloride used as the adherend 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. The adhesive layer PVC film has a polymerization degree of 500~
2000, has a thickness of 50 to 200 μm, and contains 30 to 120 parts by weight of polyester plasticizer. If the degree of polymerization is 2000 or more, it has poor wettability with the adherend, soft polyvinyl chloride. If it is less than 500, the strength is low, and as a result, the adhesive force with the adherend, soft polyvinyl chloride, is reduced, and the thickness is 50 μm.
If it is less than 200 μm, the adhesive composition cannot be sufficiently coated, and if it is more than 200 μm, irregular irregularities will occur on the surface of the soft polyvinyl chloride after bonding the two adherends. good. Next, examples of the present invention will be described. Example 1 First, a plain woven fabric (1500D/1×600D/161×70) made of polyester fibers was immersed in the pretreatment solution (A) shown in Table 1 and dried at 140 degrees for 2 minutes. Next, an adhesive layer PVC film (B, degree of polymerization:
1100, thickness: 100 μm) at 175°C for 5 seconds at a pressure of 20 kg/cm 2. Also, as a comparative example, after treatment with treatment liquid (A), post-treatment liquids (C, D, E) in Table 2 was applied uniformly at a rate of 50 kg/cm 2 using a doctor knife 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).
The film was adhered to a 0.6 mm thick sheet (containing 85 parts by weight of polyester plasticizer, Ba stabilizer, etc., hardness JIS-A 70) at a pressure of 20 kg/cm 2 for 5 seconds. In this case, after the adhesive layer PVC film is pressure-bonded or after the post-treatment liquid is applied and dried, the standing time until it is bonded to the adherend, which is a thick soft polyvinyl chloride, and the peeling force after bonding is completed. The time taken to measure is shown in Table 3. 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.

Because of this, it is highly compatible with the adherend, soft polyvinyl chloride, and the highly reactive polyisocyanate compound contained in the treatment liquid forms a film between the fiber material and the treatment liquid, and a bond layer between the treatment liquid and PVC. Since the adhesion with the film coating is improved, the adhesion strength is further improved, and furthermore, when the adhesive-treated fiber material is heated and pressurized with soft polyvinyl chloride, it adheres to the fiber material. The release or blocked isocyanate compound in the treatment solution reacts to further increase the bonding strength between the two adherends, and the adhesive treated fiber material remains untreated even if it is left in a high temperature and high humidity environment for several days. The polyisocyanate compound contained in the liquid is completely surrounded by the adhesive layer PVC film, so it is almost unaffected by moisture, so it can be stored for a long time, and it is compatible with soft polyvinyl chloride. It has excellent effects such as almost no decrease in adhesive strength, and the surface of the soft polyvinyl chloride adherend after bonding both adherends is extremely smooth.
