Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rug having a non-slip function that prevents movement on a floor material or the like.

[0002]

[Prior art]

 In recent years, due to westernization of houses, flooring materials such as wooden floors and PVC tile cushion floors have been adopted in general households. On these floor materials, rugs such as fiber tufted carpets, woven carpets, needle-punched carpets and electric carpets are often used for keeping heat and soundproofing or for aesthetic purposes.

When the frictional resistance between the rug and the flooring material is small, the problem that the rug slides and moves occurs. An example of this is the case where an electric carpet is laid on a wooden floor, but unexpected movement of the rug is dangerous.

On the other hand, conventionally, a rubber emulsion is directly applied to the back surface of a rug, or foamed to form a foam rubber. Conventional rubber emulsions such as natural rubber (NR), styrene-butadiene rubber (SBR) and methylmethacrylate-butadiene rubber (MBR) have been used for the non-slip processing of rugs. Rubber emulsions are highly deteriorated over time and have a poor anti-slip effect.

Urethane resins and soft vinyl chloride resins are also used as anti-slip materials, but urethane resins undergo severe deterioration over time, similar to general rubber-based emulsions, and plasticizers contained in vinyl chloride resins migrate to the floor. Discolor the material.

[0006] Compared with these resins, they are excellent in heat resistance and light resistance and have little change over time, so that some processing with acrylic resin emulsion is also performed, but soft acrylic resin has strong adhesiveness and lacks strength. However, hard acrylic resin has poor elasticity and insufficient anti-slip effect.

[0007]

[Problems to be solved by the device]

 The present invention has been proposed in order to improve the above-mentioned problems in such a rug, and has a non-slip function that is non-sticky, has excellent strength and elasticity, and has little change in anti-slip effect over time. The purpose is to provide a rug that has.

[0008]

[Means for Solving the Problems]

 The present invention comprises an acrylic resin emulsion (A) having a glass transition temperature of −50 ° C. to −30 ° C. and an acrylic resin emulsion (B) having a glass transition temperature of −20 ° C. to 0 ° C. Mixing resin emulsion (C) adjusted to -40 ° C to -10 ° C is compounded with 0.05 to 5% by weight of a cross-linking agent, and the back surface of the rug is coated and processed to form a non-slip portion. Or (first device), or a composition in which the composition is applied to the back surface of the rug as a non-slip part using a secondary base fabric applied and processed on a non-woven fabric or other base fabric (second device) It provides a rug with a non-slip function.

In the present invention, an acrylic resin emulsion (A) having a glass transition temperature of −50 ° C. to −30 ° C. and an acrylic resin emulsion (B) having a glass transition temperature of −20 ° C. to 0 ° C. are used. The mixed resin emulsion (C) obtained by mixing these (A) and (B) is adjusted so that the average glass transition temperature thereof is −40 ° C. to −10 ° C., preferably −30 to −15 ° C. . When the average glass transition temperature of (C) is less than -40 ° C, the adhesiveness is strong and the strength is insufficient, and when it exceeds -10 ° C, it has poor elasticity and a hard finish, and cannot be used.

In the present invention, both the anti-slip effect and the durability, which cannot be realized by one kind of acrylic resin emulsion, can be achieved by using such two kinds of acrylic resin emulsions together.

These acrylic resin emulsions contain components that react with a crosslinking agent, such as a carboxyl group, a hydroxyl group, an N-methylol group, an amide group, and a glycidyl group.

According to the present invention, by adding a crosslinking agent to the above-mentioned mixed resin emulsion (C), there is no tackiness, and durability and excellent strength and elasticity are exhibited. As such a cross-linking agent, an epoxy compound, a melamine resin, an ethylene urea compound, a blocked isocyanate compound, ethylene imine, an oxazoline compound or the like can be used.

The cross-linking agent is blended in a proportion of 0.05 to 5% by weight with respect to the mixed resin emulsion (C). If it is less than 0.05% by weight, sufficient strength cannot be obtained, and if it exceeds 5% by weight, it becomes hard and a sufficient anti-slip effect cannot be obtained.

In the present invention, stabilizers, dispersants, antioxidants, vulcanization accelerators, crosslinking agents, defoamers, preservatives, coloring agents, fillers, Compounding ingredients such as antistatic agents can be added.

The above-mentioned composition is directly applied / processed on the back surface of the rug to act as a non-slip portion, or applied / processed on a non-woven fabric or other base fabric to give a non-slip treated secondary base fabric. After that, it is bonded to the back surface of the rug to act as a non-slip part.

As the processing method of the compound, application by a bath and roll coater, spray processing, impregnation processing, foam processing by foaming, and the like can be applied. In particular, foam processing is most effective in terms of anti-slip effect. Further, in the foaming process, it may be processed so as to form a uniform thickness, or may be processed into a stripe shape in which uneven portions are alternately repeated, or a dot shape in which convex portions are scattered.

EXAMPLES The present invention will be described in more detail below with reference to examples, but the present invention is not limited to these examples as long as the gist thereof is not exceeded. In the examples, parts indicating ratios are based on weight.

Examples 1 and 2 Acrylic resin emulsion (A) having a glass transition temperature of −40 ° C. and acrylic resin emulsion (B) having a glass transition temperature of −10 ° C. were mixed at a ratio shown in Table 1, and further mixed. As a cross-linking agent, 1% by weight of an epoxy compound (Denacol EX-521, manufactured by Nagase Chemical Industry Co., Ltd.) was blended to obtain a blend. On the back side of the tufted carpet lined with a non-woven fabric as shown in Fig. 1, the above-mentioned composition is foamed and formed into a foam, which is applied and dried using the doctor knife shown in Fig. 3 and then streaked as shown in Fig. 4. It processed so that the uneven | corrugated shaped part (a: convex part, b: concave part) of a shape may be formed.

Example 3 A blend was obtained in the same manner as in Example 1 except that the blending ratio of the acrylic resin emulsion (A) and the acrylic resin emulsion (B) was changed. As shown in FIG. 2, the mixture is spray-processed on the non-woven fabric 5 so as to form a uniform thickness, and the cover carpet 9, the non-woven fabric of the electric carpet main body, the electric heater and the non-woven fabric 7 on which the mixture of the present invention is spray-processed are laminated. And integrated.
