Problems solved by technology

[0003] However, the wear resistance of the PVC wear-resistant layer is only at a moderate level, making the floor surface rough due to long-term trampling, friction, and scratches during use, which directly affects the decorative effect of the decorative layer, making the pattern of the decorative layer Or the texture is blurred and the clarity is poor

Abstract

The invention discloses a composite floor board. The composite floor board is characterized by comprising a wear resisting layer, a PVC patterned fabric layer, a base material layer, a balance layer and a mute layer which are arranged in sequence, wherein the wear resisting layer is a melamine abrasion resistant paper layer. The composite floor board has clear and vivid patterns; and in addition,the wear and scratch resistance of the composite floor board is far better than that of a regular floor board provided with a PVC wear resisting layer. Meanwhile, the invention also correspondingly discloses a manufacturing technology of the composite floor board. The manufacturing technology comprises the steps of material spreading, hot pressing, demolding and tempering; the technological stepsare simple; and in addition, the prepared composite floor board has high dimensional stability and excellent wear and scratch resistance.

Description

technical field [0001] The invention relates to a compound floor and its manufacturing process. Background technique [0002] Composite flooring is popular because of its decorative features, wear resistance, and dimensional stability far superior to traditional bamboo and wood flooring. For example, the Chinese patent with the application publication number CN104847082B discloses a flame-retardant PVC floor, including a base layer, a decorative layer on the base layer, and a wear-resistant layer on the decorative layer. The material of the base layer includes PVC powder. , a flame retardant and a coupling agent, the decorative layer is decorative paper treated with melamine, the material of the wear-resistant layer includes PVC powder and a flame retardant, and at least one of the base layer and the wear-resistant layer Materials include smoke suppressants. Choose melamine-impregnated paper for the decorative layer. [0003] However, the wear resistance of the PVC wear-r...
