Ultra-low formaldehyde impregnated paper composite structure pvc stone-plastic floor and preparation method thereof

Abstract

Belonging to the technical field of floor, the invention relates to a PVC stone plastic floor with an ultra-low formaldehyde impregnated paper composite structure and a preparation method thereof. ThePVC stone plastic floor includes a PVC stone plastic base material layer, a PVC pattern paper layer and a wear-resistant layer are laid on the upper layer of the PVC stone plastic base material layerin order, and a balance paper layer is laid on the bottom layer of the PVC stone plastic base material layer. The PVC stone plastic floor with the ultra-low formaldehyde impregnated paper composite structure has good waterproof and fire-proof performance, compared with ceramic tiles, has light mass and good toughness, is recyclable, and can completely replace ceramic tiles. Compared with PVC floor, the production process is simple, has no need for UV painting process and cold pressing, also the PVC stone plastic floor is environment-friendly, has ultra-low formaldehyde content, and accords with the standards of E0 grade or below.

Description

technical field [0001] The invention belongs to the field of floor technology, in particular to a PVC stone-plastic floor with a composite structure of ultra-low formaldehyde impregnated paper and a preparation method thereof. Background technique [0002] PVC flooring is now mature. PVC flooring is a new type of light-weight floor decoration material that is very popular in the world today, also known as "light-weight floor material". It is popular abroad and has entered the Chinese market since the early 1980s. It has been widely recognized in large and medium-sized cities in China and is widely used, such as homes, hospitals, schools, office buildings, factories, public places, supermarkets, businesses, etc. place. But there are also some problems. For example, PVC wear-resistant layer is used in almost all PVC floors, and UV coating treatment is done on the wear-resistant layer to play the role of adjusting brightness and protection, but this is inevitable in long-term ...

Problems solved by technology

But there are also some problems. For example, PVC wear-resistant layer is used in almost all PVC floors, and UV coating treatment is done on the wear-resistant layer to play the role of adjusting brightness and protection, but this is inevitable in long-term use. The process will be affected by environmental changes, especially under high temperature conditions, such as VOC and other harmful substances, which will affect people's health

And even if the PVC wear-resistant layer is treated with UV coating, its scratch-resistant effect is very poor, and scratches are easily generated

Although the same laminated floor is cheaper and wear-resistant than solid wood flooring, it is not environmentally friendly. The reinforced composite uses MDF as the substrate. MDF is made of wood powder and glue, which is airtight, has poor foot feel, is not water-resistant, and is not moisture-proof. , and high formaldehyde emission

Application number 201710549529.2, titled: An invention patent for a super wear-resistant, scratch-resistant and waterproof plastic floor and its manufacturing method, there are the following problems in practical application: 1. Formaldehyde content control, because it is made by impregnating melamine formaldehyde glue As a decorative layer, colored paper increases the formaldehyde emission of the product and affects the environmental performance of the entire product; 2. Because the first connecting layer and the second connecting layer are film materials, it is necessary to increase the production of such film materials The preparation process steps and the production difficulty of the finished product make the whole process complex and unstable; 3. UV coating and tempering processes are required to achieve the required wear resistance and gloss effect of the product, which increases the release of harmful substances such as VOC probability, and additional processes need to be added, which increases product cost and instability
