The present invention relates to an aqueous dispersion composition that improves the high frequency adhesion of vinylidene chloride copolymer resin latex, and its purpose is to improve the high frequency adhesion of flexible polyurethane foam. Conventionally, in this field, many studies have been made on improving the high frequency adhesive properties of polyurethane foams. For example, a soft foam has been obtained by impregnating or coating vinylidene chloride copolymer resin latex and drying it. (Special Publication No. 51-41910) However, there are many drawbacks compared to conventional methods. When manufacturing composite components, high-frequency bonding is performed using vinyl chloride sheets or leather as the first layer, soft foam as the second layer, and hardboard as the third layer. depends on the output of In this case, if the high frequency output is increased, the first
The layer of vinyl chloride sheet or leather melts and breaks. Therefore, it is desired that the high frequency output be as low as possible. If the adhesive force is to be increased from another aspect, the amount of resin impregnated must be increased. If the amount of resin is increased, the vinylidene chloride copolymer resin will crystallize, resulting in a lack of flexibility over time. Therefore, the amount of vinylidene chloride resin impregnated is small, the high frequency output is low, and the adhesive strength is high.
There are expectations in the market for soft foams that do not lose their hardness or texture over time. The present invention has been made to solve these difficulties, and the present inventor has arrived at the present invention as a result of extensive research. That is, the present invention contains 75 to 88 parts by weight of vinylidene chloride monomer, 5 to 17 parts by weight of vinyl chloride monomer, and 2 to 8 parts by weight of acrylonitrile monomer.
and 100 parts by weight of a vinylidene chloride copolymer resin latex obtained by polymerizing less than 1 to 0.5 parts by weight of an acrylic acid monomer, and 6 to 12 parts by weight of a special plasticizer consisting of acetyl tributyl citrate or di-2-ethylhexyl adipate. The present invention provides an aqueous dispersion composition with improved high frequency adhesion. The composition of the present invention consists of a vinylidene chloride copolymer resin latex and a special plasticizer. Vinylidene chloride copolymer resin latex consists of 75 to 88 parts by weight of vinylidene chloride monomer, 5 to 17 parts by weight of vinyl chloride monomer, and 2 to 2 parts by weight of acrylonitrile monomer.
8 parts by weight and less than 1 to 0.5 parts by weight of acrylic acid monomer, the preferred range being vinylidene chloride monomer 83
Parts by weight, 12 parts by weight of vinyl chloride monomer, 5 parts by weight of acrylonitrile monomer, and acrylic acid monomer
It is stabilized by copolymerizing 0.8 parts by weight in water in the presence of an emulsifier and a catalyst. The special plasticizer is acetyl tributyl citrate (hereinafter abbreviated as ATBC) or di-2-ethylhexyl adipate (hereinafter abbreviated as DOA).
is emulsified using a suitable emulsifier. The plasticizer that can be used is essentially ATBC or DOA due to its compatibility with the polymer, compatibility with the aqueous dispersion, volatility, etc. The aqueous dispersion composition is a composition in which 100 parts by weight of vinylidene chloride copolymer resin latex is mixed with 12 to 24 parts by weight of ATBC or DOA, which is a plasticizer emulsified to a concentration of 50%. . To emulsify the plasticizer, 50 parts by weight of the plasticizer and 50 parts by weight of a 3% by weight aqueous solution of an emulsifier (secondary alkyl sulfonate) were mixed in equivalent amounts and thoroughly emulsified using a homomixer. The method for producing the impregnated foam is to adjust the solid content of the aqueous dispersion composition to 37% by weight and impregnate it into a 5 mm thick soft polyurethane foam (density 0.016 g/cm 3 ).
Roll squeezing was performed so that the resin adhesion amount was 40 g/m 2 , dried in a 100°C dryer for 3 minutes, and heat treated at 60°C for 60 minutes. The polymer of vinylidene chloride copolymer resin latex has low-temperature meltability, does not cause blocking, and has high-frequency adhesive properties that can be bonded with lower output power than conventional products. Regarding the mixing of plasticizers, it is said that various problems occur due to a decrease in heat resistance and evaporation of the plasticizer, but such phenomena were not observed at all in the composition of the present invention. By plasticizing the polymer of the vinylidene chloride copolymer resin latex, the adhesive strength was improved, and no decrease in adhesive strength was observed even after heat-resistant treatment (80°C, 168 hours). Hereinafter, the present invention will be explained in more detail with reference to Examples. Example 1 Plasticizer ATBC or DOA was emulsified with 100 parts by weight of vinylidene chloride copolymer resin latex.
An aqueous dispersion composition was prepared by adding 6 to 12 parts by weight of the pure content of 50%, and impregnated into a 5 mm thick flexible polyurethane foam at a resin amount of 40 g/m 2 . It was dried at 100°C for 3 minutes and then heat treated at 60°C for 60 minutes. High-frequency adhesive strength was measured under normal conditions and after heat-resistant treatment (80°C, 168 hours). The results are shown in Table-1 and Table-2.
