Problems solved by technology

At present, in the field of decoration, the floors widely used by people are generally reinforced composite wood flooring or stone-plastic flooring. However, reinforced composite wood flooring has the shortcomings of poor elasticity, easy shrinkage, denaturation, non-waterproof, and short service life. Large limitations; the stone-plastic floor has the disadvantages of poor elasticity and heavy weight, and the processing adopts the process of granulation first and then molding, and the energy consumption of the product is high
Therefore, in order to meet the needs of the market, rubber flooring gradually appeared, but the general rubber flooring is made of chemical raw materials (such as polyvinyl chloride), the processing technology is complicated, the cost is high, and the processing will produce toxic gases to pollute the environment at the same time.

Abstract

The invention provides a semi-hard bamboo and wood fiber decorative base plate, which is prepared from the following raw materials (by weight): 15-35% of bamboo and wood fiber powder, 25-45% of calcium carbonate, 10-25% of PVC resin, 4-10% of EVA, 3-5% of a heat stabilizer and 5-8% of a plasticizer. Static bending intensity, elasticity modulus and dimension variance rate under heat of the above semi-hard bamboo and wood fiber decorative base plate are good, and weight of the product is reduced to make the product have the same effect of cork wood. When walking on the product, no sound is generated and foot feels more comfortable. The invention also discloses a preparation method of the semi-hard bamboo and wood fiber decorative base plate and an elastic self-adhesive floor with the application of the semi-hard bamboo and wood fiber decorative base plate.

Description

technical field [0001] The invention relates to the field of building floor materials, in particular to a semi-rigid bamboo fiber decorative base board and a preparation method thereof, and also discloses an elastic self-adhesive floor. Background technique [0002] With the improvement of living standards, people have increasingly pursued the comfort, safety and natural feeling of living quarters. At present, in the field of decoration, the floors widely used by people are generally reinforced composite wood flooring or stone-plastic flooring. However, reinforced composite wood flooring has the shortcomings of poor elasticity, easy shrinkage, denaturation, non-waterproof, and short service life. Large limitations; the stone-plastic floor has the disadvantages of poor elasticity and heavy weight, and the processing adopts the process of first granulation and then molding, and the energy consumption of the product is relatively high. Therefore, in order to meet the needs of ...
