Description

Ecological building material retaining wall decorative board and manufacturing method thereof

Technical field

The invention belongs to the field of brake pads, and in particular relates to a mosaic brake pad and a manufacturing method thereof.

Background technique

In recent years, people's living environment has gradually deteriorated. Car exhaust, toxic gases emitted by chemical plants, and various fine particles are gradually eroding our living environment. The main pollutants are as follows:

First, formaldehyde, formaldehyde is mainly derived from artificial wood, mainly used in the production of adhesives. Formaldehyde can cause cancer and can also cause fetal malformations. National standards stipulate that indoors should not exceed 0.08 milligrams per cubic meter.

The second is benzene series such as benzene, toluene and xylene. It is found in paints, glues and various interior paints. Due to the benzene aromatic hydrocarbons, people are not easy to be alert to their toxicity. However, if they are in a sealed room with benzene smell, people may experience symptoms such as dizziness, chest tightness, nausea and vomiting in a short period of time. Will lead to death. In addition, benzene can also cause cancer, cause blood diseases, etc., and has been identified as a carcinogen by the World Health Organization. The "Indoor Air Quality Hygienic Code" formulated by the Ministry of Health in 2001 stipulates that the standard of benzene in indoor air is less than 0.087 mg per cubic meter.

The third is ammonia gas. The indoor ammonia gas is mainly derived from concrete antifreeze. In the winter construction in North China, in order to improve the strength of concrete, antifreeze containing urea is added to the concrete. After the house is built, a large amount of ammonia gas in the concrete is released. In addition, ammonia in indoor air may also come from interior decoration materials. For example, most of the additives and brighteners used in furniture finishing use ammonia water. The harm of ammonia to the human body is mainly damage to the respiratory tract, eye mucosa and skin, tearing, headache, dizziness and the like. In 2001, "Household Environmental Pollution Control Code for Civil Building Engineering", the concentration of ammonia in indoor air was less than 0.2 mg per cubic meter.

The fourth is 氡, which is found in construction cement, slag bricks and decorative stone as well as in soil. The main cause of lung cancer is lung cancer, which is the second most common cause of lung cancer other than smoking. China has also established a national standard for strontium content. The new house standard is less than 100 BQ/m3, and the old house standard is 200 BQ/m3.

People who smoke indoors also emit a variety of toxic substances such as carbon monoxide, hydrocyanic acid, ammonia and aromatic compounds. In addition, the main source of outdoor PM2.5 is industrial production and automobile exhaust, while indoor and outdoor air are different, indoor gas will have some shielding effect on some outdoor dust and particle indoors, but if there is a certain component of both Superimposed indoors. The gas used for cooking and the dust generated by stacked quilts are unique indoors; home decoration and indoor smoking; housewives are used to cooking oil hot, and some people like to eat barbecue, which may produce polycyclic aromatic hydrocarbons Substances such as benzopyrenes have a greater impact on health. In addition, household appliances produce purple and infrared radiation that is unsafe for the human body.

Activated carbon can effectively absorb chemical harmful gases such as formaldehyde, methane, stupid, carbon monoxide, carbon dioxide and fine particles, as well as purple and infrared radiation, thereby achieving effective purification of air and reducing environmental radiation. Activated carbon can also adjust the humidity of the room space, with suction It has a catalytic function and effectively inhibits the reproduction of mold. In addition, activated carbon also has the function of removing pathogens such as epidemic colds and viral viruses. In the patent application No. 201510108565.6, the company discloses an activated carbon ecological building material made by using rice straw, and a preparation method thereof, which has high adsorption characteristics, can effectively adsorb PM2.5 particles and has very high radiation protection. Performance, the application of this ecological building material on the kitchen door will effectively solve the problem of poor indoor air quality.

However, at present, most of the activated carbon appears in the form of a charcoal package, and the shape is ugly, and the activated carbon is easily leaked from the charcoal package. The preparation of activated carbon into a solid block and maintaining its adsorption performance requires a relatively complicated process and high cost.
