Negative oxygen ion modified PVC hard composite floor and preparation process thereof

Abstract

The invention provides a negative oxygen ion modified PVC hard composite floor. The composite floor comprises a UV layer, a PVC wear-resistant layer, a PVC pattern fabric, a negative oxygen ion modified PVC middle material layer, and a negative oxygen ion modified PVC bottom material layer from the top to the bottom in sequence. A preparation process of the composite floor comprises the followingsteps: spreading the PVC wear-resistant layer, the PVC pattern fabric, the negative oxygen ion powder modified middle material layer, and the negative oxygen ion powder modified bottom material layer,sending the spread materials into a hot press, performing heating and pressurization, and performing cooling molding; coating the surface of a semi-finished product by a UV curing layer; sending thesemi-finished product into a tempering line for tempering, and performing natural curing; and performing trimming on the semi-finished product, performing cutting, performing slotting, and performingpacking. According to the process provided by the invention, the refractory floor prepared by the method has a higher release amount of negative oxygen ions and good scratch resistance.

Description

【Technical field】 [0001] The invention belongs to the technical field of decorative materials, and in particular relates to a PVC hard composite floor modified by negative oxygen ions and a manufacturing process thereof. 【Background technique】 [0002] With the improvement of people's living standards, there are higher and higher requirements for the health, environmental compatibility and functionality of decorative materials. [0003] The concentration of negative ions in the air is an important parameter to measure the air quality index. Medical research shows that negatively charged particles in the air can increase the oxygen content in human blood, help blood oxygen transport, absorption and utilization, promote human metabolism, improve human immunity, enhance human muscle energy, and regulate the balance of body functions role. The far-infrared rays radiated by negative ion mineral crystals can be well coordinated with the human body and can be completely absorbed ...

AI Technical Summary

Problems solved by technology

However, for most people, they stay indoors most of the time, so the long-term negative ion supply will affect the mental state and physical and mental health of the human body.

[0004] In the prior art, negative ion materials have been widely used in interior decoration materials. For example, Chinese invention patent 201510981037.1 discloses a negative oxygen ion film decorative board, which is composed of a substrate, a negative oxygen ion film material layer, and a decorative layer. Composition, the negative oxygen ion film decorative board made by the preparation method disclosed in this patent document has a low release amount of negative oxygen ions and scratch resistance
