Abstract

PURPOSE:To improve the transparency of a tile by blending the specific quantity of through-chips containing the specific quantity of transparent resin and inorganic fillers with the refraction factor thereof similar to that of the transparent resin randomly into tile composing elements. CONSTITUTION:More than 10% of through chips containing 10-40% by weight of transparent resin such as polyvinyl chloride and polymethyl methacrylate and 40-90% by weight of an inorganic filler such as diatomaceous earth and muscovite is randomly blended into tile composing elements. The transparent resin and the inorganic filler with its refraction factor similar to that of the transparent resin are kneaded uniformly to be molded, thus obtaining excellent transparency, and thereby an excellent design can be obtained.

Description

[Detailed description of the invention] [Industrial field in Icheon] The present invention relates to transparent through-chip tiles. [Prior Art] Calcium acetate is usually used as a filler in through-chip tiles made by UC.

[Problems to be Solved by the Invention] The conventional through-chip type tiles are opaque, and even if other colored through-chips are mixed in to add a pattern, a pattern with excellent transparency cannot be obtained. be.

[Means for solving the problem] The problem is to solve the problem by using a transparent resin with a total solid content of 10 to 40 according to the present invention.
This can be solved by randomly blending at least 10% of through chips containing 40 to 90% by weight of an inorganic filler and having a refraction of 4<4% by weight and similar to that of the transparent resin. A conventional method for manufacturing sluch-knob tiles is used to manufacture the transparent sluch-knob tile of the present invention.

For example, the ingredients of the above composition are kneaded under pressure with a Banbury mixer, heated and kneaded with a mixing roll, made into a sheet with a calendar roll, and then shaped into a sheet with a crusher of approximately 3 to 10 mm in size.
Manufacture knobs. Usually, for patterning, two to four types of colored through-chips are mixed with the transparent through-chip and made into a sheet, which is then rolled with a calendar roll and cut with a cutter to produce a transparent through-chip tile. . It is also possible to produce a through-chip tile rich in design by mixing flaky aluminum, silver, gold, glass, or pearl essence with the transparent through-chip/I-type tile of the present invention. Next, the composition components used in the present invention will be explained.

Transparent resins include polyvinyl chloride and polyvinyl chloride/vinyl acetate copolymer. Polystyrene, polymethyl methacrylate, polyvinyl acetate, polyvinylidene chloride, polyvinyl alcohol, etc. can be used9, and the refractive index of these resins is 1.45 to 1.63. A particularly preferred resin is polyvinyl chloride. One example is polymethacrylate methacrylate. The appropriate amount to use is 10 to 40% of the total solid content, and if it is less than 10%, it will not have enough strength as a sheet flooring material.
If it exceeds 40-6, it becomes difficult to smooth the surface of the sheet-like flooring material by processing by the commonly used roll rolling method.

Examples of inorganic fillers that have a refractive index similar to that of the transparent resin include nepheline sinite, diatomite, kaolin, halloysite, talc, white clouds, calcined sauce, and zeolite. The refractive index of these fillers is 1.49-1
．． 64. 9 The combinations of these fillers and transparent resins are arbitrary, but particularly preferred combinations are polyvinyl chloride and nepheline sinite, polyvinyl chloride and diatomaceous algae, and polyvinyl chloride and halloysite. Examples include polymethyl methacrylate and zeolite.

The amount used is 40-90% of the total composition components. Furthermore, when used in combination with conventional colored through-chip tiles, it is necessary to use the transparent through-chip type tiles of the present invention in an amount of 10% or more. If less than 10% 11'4 is used, sufficient transparency cannot be obtained.

[For use] When the transparent resin and the inorganic filler having a refractive index similar to that of the transparent resin are uniformly kneaded and molded in the transparent slouche/fub type tile of the present invention, the refractive index is similar to that of the transparent resin, so that the transparent resin has excellent transparency. In addition, transparent through-chip tiles manufactured by heating and kneading colored through-chips, forming sheets, rolling, cutting, and molding have the effect that the pattern created by the colored through-chips does not have a three-dimensional effect in its transparency.

The tile has an excellent design with three types of colored through-chips clearly standing out in its transparency.

[Effects of the Invention] The transparent through-chip according to the present invention exhibits excellent transparency because the refractive index of the resin and the inorganic filler are similar. Furthermore, if you add colored through-dip or flaky aluminum, gold, silver, etc. 33, the colored pattern will stand out in the transparency, or the flaky aluminum, gold, silver, etc. will shine and have an excellent design effect.9
