Low-carbon environmental-protection lightweight sound-insulation partition wall board

Abstract

The invention discloses a low-carbon environmental-protection lightweight sound-insulation partition wall board prepared from the following raw materials: aluminum stearate, starch grafted polycaprolactone, cationic polyacrylamide, diethanolamide, aluminum potassium sulfate dodecahydrate, sorbitol monooleate, soybean lecithin, a soap powder, magnesium chloride, a glass powder, urea, sodium carbonate, starch, hexadecyl ammonium bromide, a talcum powder, methylsilicone oil, a silane coupling agent kh550, fly ash fibers, a VAC / E latex powder, cement, ceramsite, sand, a naphthalene water reducing agent, an alunite expansion agent, polystyrene and water. The prepared lightweight partition wall board has the advantages of light weight and low cost, has the characteristics of relatively good heat preservation, heat insulation, corrosion protection, high strength, firmness, durability and beautiful appearance, and has quite wide market prospect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a low-carbon, environment-friendly, lightweight sound-insulating partition board. Background technique [0002] The concept of building energy conservation has been widely concerned by countries all over the world. The main reason for the low efficiency of building energy utilization is that the insulation and airtightness of the building envelope are poor, resulting in a large amount of energy waste. For this reason, the development of building materials with good thermal insulation performance and large heat capacity has become the key to energy saving. In recent years, foamed polystyrene insulation mortar has become an entry point for research on energy-saving building materials in my country due to its low thermal conductivity, good weather resistance, and convenient construction. Lightweight building envelope materials can not only effectively reduce the weight o...

Problems solved by technology

Among them, fly ash has potential chemical activity, fine particles, and contains a large number of vitreous beads. It can play an active effect, a shape effect and a particle filling effect when mixed into dry-mixed mortar. It can be seen from the experimental data that the addition of fly ash The compressive strength of the material can be improved, and the dry apparent density decreases, but with the increase of the proportion of fly ash, the proportion of cement binder also decreases relatively, resulting in a gradual decrease in the compressive strength of the material
