Problems solved by technology

The use of synthetic vegetable fatty acid esters to replace the small molecule plasticizers of the original technology solves the problem that the chlorine content of the product is reduced due to the addition of a large amount of plasticizers, resulting in a decrease in flame retardancy

Embodiment Construction

[0045] The present invention provides an environmentally friendly PVC flame-retardant and wear-resistant floor leather and a preparation method thereof. In order to make the purpose, technical scheme and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] Implementation example one:

[0047] 1. Mixture:

[0048] A. Foaming layer plastisol, weigh the raw materials in the following formula according to the mass parts, set aside:

[0049]

[0050] Put the above-mentioned prepared raw materials except synthetic vegetable fatty acid ester into a high-speed mixer, stir for 10 minutes, discharge into a low-speed cold mixer for stirring, discharge when the temperature of the material is lower than 50°C, and set aside.

Abstract

The invention discloses environment-friendly PVC flame-retardant wear-resistant floor leather and a preparation method thereof. The environment-friendly PVC flame-retardant wear-resistant floor leather is prepared by coating base cloth with foaming layer plasticized paste, performing foaming, performing coating with wear-resistant layer plasticized paste, performing plasticizing, performing printing and performing UV treatment and embossing. When the addition amount of nano calcium carbonate in a formula of the plasticized paste reaches 20 parts or more, the rheological property of shear thinning is achieved, and a foaming layer with the maximum thickness of 4 mm can be obtained at one time through a scrape coating or roll coating process, so that the production process is simplified and the production cost is reduced. According to formulae of the foaming layer and a wear-resistant layer, synthetic vegetable fatty acid ester with the flame-retardant property and polishing residues withthe flame-retardant and smoke-suppressing properties are added, and the synthetic vegetable fatty acid ester and the polishing residues are cooperatively used to achieve the synergistic flame-retardant and smoke-suppressing effect. The problem that the flame retardant performance is reduced as the chlorine content of the PVC floor leather is reduced due to the addition of a small molecular plasticizer is solve. The problem of environmental pollution caused by difficult recycling and waste landfill of stone, ceramic tile and artificial stone polishing brick residues is solved.

Description

technical field [0001] The invention relates to the technical field of PVC floor leather, and mainly relates to an environment-friendly PVC flame-retardant and wear-resistant floor leather and a preparation method thereof. Background technique [0002] The preparation method of PVC floor leather in the prior art is to use canvas as the base cloth, apply PVC plasticizing paste to obtain through high-temperature plasticization or calender and laminate PVC film to obtain. Whether it is PVC floor leather prepared by coating PVC plastisol or calendering and laminating PVC film, the plasticizers in the formula are mainly phthalic acid plasticizers such as DOP and DBP. Such plasticizers are highly toxic and easy to extract, and the import of related products has been banned in Europe. PVC has a high chlorine content and has good flame retardancy. However, due to the addition of extremely flammable small-molecule plasticizers, such products become flammable items, and a large amoun...
