Problems solved by technology

These shortcomings greatly limit the application of chopped glass fiber in PVC flooring
[0004] The PVC floor on the market has good flexibility, but the product with too low hardness is easy to be deformed by force, and the straightness is poor, which will cause gaps in the paving

Abstract

The invention discloses a preparation method of an anti-slip and sound-absorbing composite floor, which belongs to the field of floor manufacturing, and comprises step 1: drawing reinforcing material; step 2: bonding; step 3: preparing a wear-resistant layer on the top surface of the bonded product; step 4: Cold paste the sound-absorbing layer on the bottom surface of the laminated product; Step 5: Coat the anti-slip layer; Step 6: Perform UV treatment on the surface of the wear-resistant layer; Step 7: Die-cut. The invention also discloses an anti-slip and sound-absorbing composite floor, which comprises a wear-resistant layer, a printing layer, a middle material layer, a strengthening material layer, a bottom material layer, a sound-absorbing layer and an anti-slip material layer sequentially from top to bottom. The invention provides an anti-skid and sound-damping composite floor and a manufacturing method thereof, which have the technical effects of good anti-skid effect, small expansion, good straightness, sound and noise reduction, and easy assembly and disassembly.

Description

technical field [0001] The invention belongs to the field of floors, and in particular relates to a method for manufacturing an anti-skid and sound-absorbing composite floor and a composite floor manufactured by the method. Background technique [0002] The glue-free floor is easy to install and dismantle. It does not use any glue and is directly laid on the ground. In recent years, people have put forward noise reduction requirements for the glue-free floor. Most of the sound-absorbing floors on the market are pasted on the bottom layer of the glue-free floor. Cork, rubber or foam materials are used to reduce noise, but the floor of this structure has no bonding force with the ground. During use, the user needs to use adhesives for construction to prevent the floor from moving. Floor adhesives are all environmentally friendly adhesives. The disadvantages here mainly refer to the troubles brought to the paving, which are labor-intensive and time-consuming, and it is also ver...
