Description
Technical Field
The invention relates to a fireproof interior wall decorative material, in particular to a novel shell-based dry powder fireproof interior wall decorative material.
Background
The explosion fire accidents happen frequently in the last two years, and casualties and property loss are countless. In order to meet the pursuit of people on beauty, a layer of paint is generally used for decoration in modern decoration rooms. The paint is generally non-fireproof or inflammable material, and can decompose toxic and harmful gas at high temperature. The method also becomes a great potential safety hazard while meeting the pursuit of people for beauty. Special coatings, called fire-retardant coatings, applied to surfaces of flammable substrates to modify the fire characteristics of the material surface and retard the rapid spread of fire, or applied to building components to increase the fire endurance of the component. The statistical data of fire fighting and disaster relief shows that the fire death rate in a fire scene is very small, and the smoke death rate is as high as 75-80%. Accordingly, the safety of the fire-retardant coating after encountering fire is questioned by people outside and inside the industry, and the combustion products are considered to be serious injuries to personnel and fire fighters who do not escape from the fire scene, and meanwhile, the fire-retardant coating causes great environmental pollution.
In recent years, most of oil-based coatings are on the market, the coatings adopt organic solvents as dispersion media, the main components of the coatings are organic molecular components, the coatings are flammable, and the organic solvents and organic matters are easy to volatilize. Not only causes pollution to the environment, but also damages the health of people. Most of the intumescent fire-retardant coating (CN 106957586A) adopt C-N-P or C-N-P-Cl series, and a large amount of chemical substances such as melamine, ammonium polyphosphate, ammonium borate, paraffin chloride and the like are used, so that toxic and harmful gases such as NH are decomposed after being heated3、HCl、NOXCO, etc.
The influence of solid waste on the environment is receiving more and more attention, and the recycling of various solid wastes has become a new research direction in the material field. With the rapid development of marine aquaculture industry in China, the influence of shells on environmental pollution in coastal areas is greater and greater, and the shell pollution becomes one of the environmental problems to be solved urgently in coastal areas.
In conclusion, the field needs a new shell-based fireproof interior wall decoration material with fireproof function, low cost and the function of being prepared in use.
