Problems solved by technology

[0006] In order to solve the warping problem of the printed block carpet, the American Lincoln is connected with the EVA adhesive layer by the asphalt layer. The asphalt layer has good water resistance, which can reduce the infiltration of water, and the asphalt layer is stiff, which can be solved very well. The warping problem of printed block carpets, but due to the large performance difference between PU bitumens, it is not easy to bond, resulting in easy delamination of carpets

Abstract

The invention provides a blocky carpet and a preparation method thereof. The carpet comprises multiple layers of structures which are sequentially a blank carpet layer, an ethylene-vinyl acetate copolymer (EVA) adhesive layer, a first polyurethane (PU) adhesive layer, a glass wool cloth layer, a second PU adhesive layer and a non-woven fabric protection layer, wherein the EVA adhesive layer is prepared from 30 to 50 weight parts of ethylene-vinyl acetate copolymer, 10 to 50 weight parts of calcium carbonate, 1 to 2 weight parts of auxiliary materials, 8 to 40 weight parts of insoluble silicate substances, and 10 to 20 weight parts of water. Compared with a blocky carpet in which an asphalt layer is connected with an EVA adhesive layer in the prior art, the blocky carpet which is prepared from an EVA adhesive containing silicate substances and is provided with the double PU adhesive layers has the advantage that the insoluble silicate substances are added into the EVA adhesive, a good waterproof effect is achieved, the infiltration of the moisture is reduced, and the required baked strength is reduced, so that the warpage of the blocky carpet is reduced; and by the double PU adhesive layers, a layering phenomenon caused by the difference of materials of the asphalt layer and the PU adhesive layer is also reduced.

Description

technical field [0001] The invention belongs to the technical field of carpet production, in particular to a block carpet and a preparation method thereof. Background technique [0002] According to different styles of supply, carpets can be divided into carpets supplied in whole rolls and block carpets. Block carpets can be laid flexibly, and the carpets in severely worn parts can be replaced at any time. [0003] Block carpets mainly include PVC rubber bottom, asphalt bottom and PU carpet. PU carpet is coated with a layer of high elastic polyurethane material on the back of the carpet. Compared with ordinary PVC bottom and asphalt bottom carpet, PU carpet has the following advantages: Compared with the asphalt carpet, the bottom has more suitable softness, better elasticity, and is more comfortable to stand on; the bottom adopts a soft foam layer, which does not directly contact the ground, which improves the thermal insulation performance; the existence of air in the soft...
