Problems solved by technology

[0004] Existing color flakes or rock flakes, such as the rock flakes disclosed in the CN 106277937 A patent, are mainly made of organic resins, curing agents and pigments. Simultaneously, in order to prevent the adhesion of the rock flakes, Shuangfei powder, talcum powder, etc. are added thereto. Powder, the imitation stone coating made of such color flakes or rock flakes, because the color flakes or rock flakes are mainly made of organic resins, curing agents and pigments, the fire resistance is poor, there is no flame retardancy, the fire resistance level is low, and there are serious potential safety hazards, and due to the addition of Shuangfei powder, talc powder and other powders, the existing color flakes or rock flakes are brittle and poor in toughness, and are easy to break and crack in actual use.

preparation example Construction

[0054] Another aspect of the present invention, such as figure 1 As shown, a method for preparing the above-mentioned flame-retardant flexible composite color sheet is provided, comprising the following steps:

[0055] S10. Production of flexible slurry. Mix and disperse different types of materials for making flexible slurry into continuous uniform viscous liquid slurry through high-speed dispersing equipment or grinding equipment. The color of the flexible slurry is the color of the required stone-like effect prevail;

[0056] S20, forming a compound film, coating the prepared flexible slurry on the substrate treated with silicone oil through a spraying or scraping process, and continuously forming a film into a composite film;

[0057] S30, drying and crushing, the composite diaphragm is dried in a 50-120°C oven, demoulded, and then mechanically crushed by a crusher;

[0058] S40, sieving and mixing, after the crushed composite diaphragms of different colors are mechanica...

Embodiment 1

[0063] In this embodiment, the weight content of each component of the flexible slurry is:

[0064]

[0065] The production process of the flame-retardant flexible composite color film of the present embodiment is as follows:

[0066] First, prepare colored flexible slurry, and the color of the slurry is subject to the color of the required stone-like effect; secondly, after the colored slurry is prepared, it is scraped or sprayed on the silicone oil-treated base paper or special Teflon-based fabric; then dried with hot air in an oven at 50-120°C, crushed and sieved after demoulding; finally add 5% non-halogen flame retardant and mix to prepare a flame retardant with a thickness of 0.05-0.3mm Combustible flexible composite color film.

Embodiment 2

[0068] In this embodiment, the weight content of each component of the flexible slurry is:

[0069]

[0070] The production process of the flame-retardant flexible composite color film of the present embodiment is as follows:

[0071] First, prepare colored flexible slurry, and the color of the slurry is subject to the color of the required stone-like effect; secondly, after the colored slurry is prepared, it is scraped or sprayed on the silicone oil-treated base paper or special Teflon-based fabric; then dried with hot air in an oven at 50-120°C, crushed and sieved after demoulding; finally, 8% non-halogen flame retardant is added and mixed to obtain a flame retardant with a thickness of 0.05-0.3mm Combustible flexible composite color film.

Abstract

The invention provides a flame retardant flexible composite color flake and a preparation method thereof. The flame retardant flexible composite color flake is prepared by compounding a flexible slurry and a substrate, the flexible slurry mainly comprises organic resin 10-30%; inorganic salt solution 20-35%; non-halogen flame retardant 35-40%; inorganic filler 10-30%; inorganic thickener 0.5-2%; pigment 0-5%; and water 5-10%. According to the flame retardant flexible composite color flake provided by the invention, a plurality of kinds of inorganic substances such as an inorganic salt solution, an inorganic filler and an inorganic thickener are added into an organic film forming substance, with use of an inorganic modified resin compounding technology, the heat calorific value of combustion of the final composite color flake is greatly decreased and the flame retardancy of the composite color flake is improved, and meanwhile with the addition of the non-halogen flame retardant, the composite color flake is endowed with a higher oxygen index, the flame retardancy of the composite color flake is further improved, the toughness of the composite color flake is improved, the composite color flake is not easy to break and crack in actual use, and defects of prior art are overcome.

Description

technical field [0001] The invention relates to building and decoration materials, more specifically, to a flame-retardant flexible composite color sheet and a preparation method thereof. Background technique [0002] As a high-grade building decoration material, natural stone is widely used in indoor and outdoor decoration design, curtain wall decoration and public facilities construction because of its natural pattern, high hardness, wear resistance, good durability and calm and atmospheric decorative effect. [0003] However, due to the high cost and heavy weight of natural stone, the gap between the stones is too large, it is difficult to cut, seamless splicing cannot be achieved, the elasticity is insufficient, and cracks will occur when impacted, which will easily cause construction difficulties, high-altitude drop, etc. Harmful, and the radioactive substances it contains are likely to cause hidden dangers such as radiation to the human body, and damage the environment...
