Problems solved by technology

[0002] Existing composite flooring generally has shortcomings such as low product toughness, high shrinkage rate and expansion rate. In the actual production and use process, these determinations lead to relatively poor quality of the product, and the quality cannot be guaranteed, thus making the product relatively low in cost performance

Abstract

The invention relates to the field of composite floor production, in particular to a composite floor middle layer material with superior toughness, which consists of 100 parts by mass of PVC, 36 parts of plasticizer, 2 parts of stabilizer, 510.6 parts of calcium carbonate, and acrylonitrile-containing 7 parts of nitrile rubber; the content of acrylonitrile in the nitrile rubber is 31-35%; the preparation method of the middle layer material of the composite floor with superior toughness, the PVC powder of formula quantity, plasticizer, stabilizer are placed Mix and stir in the mixing equipment for 15 minutes; add calcium carbonate and mix and stir again for 15 minutes to make it fully stir and mix evenly; finally add nitrile rubber and mix and stir again for 15 minutes, so that the materials are mixed evenly. The shrinkage rate of the middle layer material of the composite floor obtained by the method is less than or equal to 0.03%, the expansion rate is less than or equal to 0.1%, and its hardness can reach 65°.

Description

technical field [0001] The invention relates to the field of composite floor production, in particular to a composite floor middle layer material with superior toughness and a preparation method thereof. Background technique [0002] Existing composite flooring generally has shortcomings such as low product toughness, high shrinkage rate and expansion rate. In the actual production and use process, these determinations lead to relatively poor quality of the product, which cannot be guaranteed, thus making the product relatively low in cost performance.
