Environment-friendly bamboo charcoal plate capable of effectively adsorbing and automatically degrading formaldehyde and preparation process of bamboo charcoal plate

Abstract

The invention discloses an environment-friendly bamboo charcoal plate capable of effectively adsorbing and automatically degrading formaldehyde. The environment-friendly bamboo charcoal plate comprises raw materials in percentage by mass as follows: 10%-50% of 200-mesh high-temperature bamboo particles, 15%-50% of 120-mesh low-temperature bamboo particles, 18%-19% of natural resin, 2%-3% of a composite stabilizer, 1%-2% of a density reduction agent, 2%-7% of bamboo fiber or reed fiber or carbonized bamboo powder, 1%-1.5% of nanoscale titanium dioxide powder, 1%-1.5% of a compatilizer, 0.5%-1% of light calcium carbonate, 0.5%-1% of calcium oxide, 1%-2% of PE (poly ethylene) wax serving as an outer lubricant, 1.5% of stearic acid serving as an inner lubricant, 0.5%-1% of CPE (chlorinated polyethylene), 0.5% of a dispersing agent, 0.5%-1% of a coupling agent and 0.5%-1% of a foaming agent. A preparation process comprises steps of material preparation, mixing, cooling, forming and cutting. With the adoption of the environment-friendly bamboo charcoal plate and the preparation process, the problem that bamboo charcoal cannot be automatically degraded after adsorbing formaldehyde is effectively solved, secondary pollution is avoided, and the charcoal plate has a high environmental protection property and is pollution-free, harmless and recyclable.

Description

technical field [0001] The invention relates to a board, in particular to an environment-friendly bamboo charcoal board capable of effectively absorbing and automatically degrading formaldehyde and a preparation process thereof. Background technique [0002] With the rapid development of real estate, various building materials are widely used in interior decoration, causing indoor environmental pollution is becoming increasingly serious. Formaldehyde is one of the most widespread indoor air pollutants. In addition to causing irritant and chronic diseases to the human body, formaldehyde can also react with ionic chlorides in the air to generate carcinogens—dichloromethyl ether. Indoor furniture, floors, carpets, tobacco, deodorants, disinfectants, etc. can release formaldehyde. Among them, decorative panels are the main source of harmful substances such as formaldehyde and benzene. The so-called bamboo charcoal boards currently on the market are either decorative products m...

Problems solved by technology

Due to the limitations of its characteristics, shape, raw material formula and production method, although the carbon products currently on the market have the function of adsorbing harmful pollutants, they have poor adsorption, low hardness, and insufficient nail-holding force, so they cannot be used as furniture panels. Function, the most important thing is that it cannot effectively degrade automatically after absorbing formaldehyde, and becomes the second pollution source, causing secondary pollution and seriously affecting human health. Due to the problem of technical formula, it can effectively absorb and automatically degrade formaldehyde, etc. Harmful substances, and environmentally friendly bamboo charcoal plates with natural fragrance are still blank
