Modified diatom-ooze interior decorative material and production technique thereof

Abstract

The invention relates to a modified diatom-ooze interior decorative material which is prepared from the following components in percentage by weight: 30-32% of modified kieselguhr, 22-24% of coarse whiting, 5-8% of calcium hydroxide powder, 4-6% of wood fiber, 3-4% of rubber powder, 1-2% of humectant, 22-23% of meerschaum wool and 8-10% of talcum powder. The production technique comprises the following steps: naturally drying and weathering kieselguhr raw ores, detecting the adobe, grading, and transporting to a processing workshop; pulverizing, carrying out air separation, adding a cosolvent, calcining in a high-temperature calcining kiln to remove water and organic impurities, pulverizing, grading repeatedly, carrying out air separation to remove inorganic impurities, and proportionally mixing with calcium hydroxide, coarse whiting, natural rubber and the like. Compared with the existing diatom-ooze product, the modified diatom-ooze interior decorative material provided by the invention has superstrong adsorption capacity, can not shed powder or fade, can be scrubbed with a wet rag, has the advantages of long service life (more than 20 years), no edge tilting, no shedding, no fading and oxidation resistance, and always looks new.

Description

technical field [0001] The invention relates to a modified diatom mud interior decoration material and a production process thereof. Background technique [0002] With the development of society and the pursuit of human quality of life, people have higher and higher requirements for indoor environment. Because people spend 70%-90% of their time indoors, if there are too many harmful substances in the living room, it may cause various diseases of the human body. Relevant national departments conducted spot checks on interior decoration materials, and found that 68% of them had toxic gas pollution. These materials volatilized more than 300 organic compounds such as formaldehyde, ammonia, benzene, toluene, xylene, and radioactive gas radon. These harmful substances can cause headaches, nausea, convulsions, dyspnea, etc. Repeated exposure can cause allergic reactions, such as asthma, allergic rhinitis and dermatitis, etc. Long-term exposure can cause cancer (lung cancer, le...

Problems solved by technology

However, the bulk density of existing diatom mud products on the market is relatively heavy, generally above 0.9 g / ml, mainly because the content of diatomite is low, and the diatomite pore structure used is homogeneous before adding other additives. Uncured, its pore structure is unstable, easy to collapse, and its adsorption is not ideal

Therefore, after spraying or pouring water, the existing diatom mud products will lose powder or color when rubbed by hand, and even mud can be mixed. When scrubbing, powder or color will appear on the surface
