Embodiment

[0016] One of embodiment: Utilize the tourmaline composite material that makes is applied to PVC artificial leather processing technology

[0017] The tourmaline composite material described in the present invention is made based on the technical scheme disclosed in the Chinese patent (patent application number 02123892) "Tourmaline powder capable of efficiently generating negative air ions and its preparation method". Concrete preparation steps are as follows:

[0018] First, the calcium carbide gas ore is selected, water-selected, and impurities are removed, and it is pulverized into an ultra-fine tourmaline powder with a particle size of less than 10 microns through a jet mill; then the ultra-fine tourmaline powder is heat-treated in an electric furnace for 1- 3 hours, the temperature range is 100-900°C, not exceeding 900°C; then the treated tourmaline ultrafine powder is treated with acid or alkali, and dried; then the industrial rare earth phosphate or oxide ultrafine Gr...

Abstract

The preparation process of artificial PVC leather and synthetic PU leather to release negative ion effectively includes the following steps: treating tourmaline mineral through sorting, water selecting, eliminating impurity, airflow grinding, acid or alkali treating; mechanical and chemical compounding tourmaline powder with RE salt or oxide and nanometer semiconductor material to obtain nanometer composite tourmaline material; adding the nanometer composite tourmaline material in 1.5-20 wt% into the material for artificial PVC leather and synthetic PU leather; and conventional artificial leather preparing process. The present invention added the negative ion releasing function to artificial PVC leather and synthetic PU leather, and negative ion with powerful oxidizing property is utilized to destroy bacteria's activity and to deodorize through reaction with various bad smell, such as ammonia, benzene, formaldehyde, etc.

Description

technical field [0001] The invention relates to a preparation method of PVC artificial leather and PU synthetic leather, in particular to a preparation method of PVC artificial leather and PU synthetic leather capable of efficiently releasing negative ions. Background technique [0002] In physics, charged atoms and atomic groups (including molecules) are called ions. Negative ions are charged atoms and atomic groups (including molecules). In 1902, the scientific community had identified the biological significance of air ions. In 1938, there was a treatise on "The Practice of Air Ions" in Japan. In 1980, the German medical community took the lead in proving that people in places with more positive ions had a higher rate of various diseases and more traffic accidents. Where the "landscape" is good, there are many negative ions, the air is obviously fresh, and the incidence rate is low. The main effect of "negative ions" on the human body is calming, ...
