Abstract

The invention discloses an improved foamed square soft-bottom carpet. The improved foamed square soft-bottom carpet comprises a blanket carpet layer, an EVA (ethylene-vinyl acetate) glue precoating layer, an upper PVC (polyvinyl chloride) gluing layer, glass wool cloth and a lower foaming PVC gluing layer sequentially from top to bottom. The invention further discloses a preparation technology of the improved foamed square soft-bottom carpet, including: coating EVA glue on the back of the blanket carpet layer, and solidifying by heating to obtain a blanket carpet with the precoating layer; according to glue matching and designs of technological parameters, adding the glass wool cloth between the upper PVC gluing layer and the lower foaming PVC gluing layer, compositely compressing the upper PVC gluing layer and the lower foaming PVC gluing layer with the blanket carpet with the precoating layer, and putting in a drying oven for plasifying reaction so as to shape the square soft-bottom carpet. The preparation technology of the improved foamed square soft-bottom carpet has the advantages that usage of a large amount of raw materials can be reduced, elastic property of the improved foamed square soft-bottom carpet can be improved, quality of a traditional square PVC carpet is improved and competitiveness of traditional products is enhanced.

Description

technical field [0001] The invention belongs to the technical field of carpet production, and in particular relates to a block-shaped energy-saving and environment-friendly foam-improved PVC block-shaped soft-bottomed carpet and a preparation method thereof. Background technique [0002] According to the different styles supplied, carpets can be divided into whole roll carpets and carpet tiles. Carpet tiles are flexible in handling and laying, and the carpets in severely worn parts can be replaced at any time. [0003] Carpet tiles mainly have asphalt bottom, PVC bottom and PU bottom. The grade of asphalt bottom is lower and the price is cheaper. The PU bottom carpet has good elasticity, soft and comfortable foot feeling, and has thermal insulation and noise reduction performance, but the price is relatively high, and the current market share is relatively low. The market is dominated by traditional PVC carpets. However, PVC carpet has inelasticity, hard foot feeling, and...
