Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to rock wool blend paper. Another object of the present invention is to provide a rock wool blended paper that is lightweight and has excellent folding durability, one-dimensional stability in tensile strength, and suitability for polyvinyl chloride sol coating as a base material for polyvinyl chloride-based long flooring materials.

Conventionally, asbestos paper has been used as a base material for polyvinyl chloride-based long flooring materials.

The asbestos paper is made by using asbestos fiber as the main raw material, adding a small amount of organic fiber to it, and adding synthetic rubber latex as a binder, and then using a Fourdrinier or round net paper machine to process a mixture of soot and 2/2 obtained by adding asbestos fiber as the main raw material and a binder such as synthetic rubber latex. Obtained by papermaking. However, asbestos fibers have the drawbacks of low productivity and heavy fibers due to poor -P water resistance. Another disadvantage of asbestos paper is that it has low folding durability, and the fine powder of asbestos fibers poses a risk of health problems such as pneumoconiosis to those who handle it. - The inventors of the present invention solved these problems with asbestos paper (after intensive study), they came up with the invention of an excellent polyvinyl chloride-based Rock Cool Warm Paper.

The present invention uses rock wool and pulp at 2 o: so to 8
0:20. Preferably, 5 parts by weight or more of synthetic polymer latex such as synthetic rubber latex is added as a binder to the 8G mixed fibers in a weight ratio of 0 to 70:80 per 100 parts by weight of the mixed fibers.

The present invention relates to a method for producing rock wool mixed paper, preferably by adding 8 parts by weight or more.

Rock wool in the present invention is made by melting raw materials such as pig iron slag, minerals mainly composed of silicic acid, and limestone in a keeper, flowing it from the bottom of the furnace, and blowing it with centrifugal force, compressed air, or high-pressure steam. Refers to the obtained amorphous mineral fiber. In the present invention, when the blending ratio of rock wool becomes low,
Underwater dimensional stability and thermal dimensional stability deteriorate. Conversely, when the blending ratio of rock wool increases, the f1 degree and suitability for polyvinyl chloride sol coating decrease.□What does suitability for polyvinyl chloride sol coat mean? Refers to whether wool and/or pulp is shed from the paper and carried into the coating layer. When rock wool and Matasha pulp are brought into the coating layer, the sol in that area rises or the pulp protrudes from the coating layer.

Decreases the surface properties of the coating layer and significantly lowers its value as a product - The blending ratio of rock wool and pulp for mixed paper suitable as a base material for PVC-based flooring materials is rock wool: pulp = 20:80 The weight ratio is preferably from #180 to so:go, preferably from #180 to 70:80.

Synthetic rubber latex etc. in the present invention are carboxylated 88R, carboxylated NBR, carboxylated MB

Paper G2. In view of dimensional stability and suitability for polyvinyl chloride sol coating, it is necessary to add at least 5 parts by weight, preferably 8 parts by weight or more, to 4,118,100 parts by weight of the mixture of rock wool and pulp. Further, in view of the above-mentioned physical properties, it is better to add a larger amount of synthetic rubber latte tux, etc., but in consideration of paper forming properties and economical efficiency, it is preferably 30 parts by weight or less.

In addition to the above-mentioned rock wool, pulp, synthetic rubber latex, etc., the mixed paper of the present invention contains organic Ik fibers other than pulp, and binders other than synthetic rubber latex.

Fillers, stabilizers for synthetic rubber latex with no vulcanizing agent, anti-aging agents, etc. may be added.

Organic fibers other than pulp include linen, cotton, rayon, vinylon, boria, polyester, polyolefin,
This refers to polyvinyl chloride, polyacrylonitrile, etc. Also, binders other than synthetic rubber 2tex, etc. include melamine formaldehyde resin, axillary formaldehyde resin,
Examples include boria-based epichlorohydrin resin, CMC, etc.

Furthermore, as fillers, clay, Merck, titanium dioxide,
There are also powders such as aluminum silicate and aluminum silicate.

The powder wool used in the present invention was free of particles.

A so-called citrus-free type is preferred. If particles are mixed in the mixed material, the surface properties will be reduced, and the suitability for coating with a single-layer polyvinyl chloride sol will be reduced.

It may inhibit adhesion with vermilion.

If necessary, surface coating may be applied to the P-Tsuku wool blend paper of the present invention by on-machine or off-machine.
This treatment further improves the surface properties of the mixed paper □ Hereinafter, the present invention will be explained with reference to Examples.
