Environment-friendly sound insulation mortar for core board of partition board

Abstract

The invention discloses environment-friendly sound insulation mortar for a core board of a partition board. The environment-friendly sound insulation mortar is prepared from polymethacrylate, castor oil, methylcellulose, wool fat, polyoxyethylene lauryl ether, Vaseline, silicone acrylic emulsion, cyclic methylsiloxane, water-soluble chitosan, sodium hexametaphosphate, trehalose, aluminum powder, aluminum oxygen chamotte, original bamboo fiber, tailing sand, sodium methyl silanolate, fly ash fiber, cement, pottery grain, sand, naphthalene water reducer, foaming agent, polystyrene and a proper amount of water. Through limitation of the raw material mixture ratio of slurry and curing and maintenance processes in a preparation process, the obtained partition board has the performance advantages of light weight, quick condensation and hardening, high intensity, heat preservation, heat insulation, fire protection and acid and alkali resistance, has the environment friendliness advantages of nontoxicity, harmlessness, freeness from pollution and freeness from radiation, and is a novel multifunctional building material.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a sound-insulating and environmentally-friendly mortar for a core board of a partition wall. 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 t...

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
