Novel cement-based particle blend non-combustible light composite heat preservation board and processing method thereof

Abstract

Particularly relating to the field of composite heat preservation boards, the invention discloses a novel cement-based particle blend non-combustible light composite heat preservation board and a processing method thereof. The composite heat preservation board comprises the following components by weight: 80-100 parts of Portland cement, 30-50 parts of modified montmorillonite, 10-15 parts of flyash, 1-5 parts of a composite foaming agent, 1-5 parts of a polycarboxylic acid water reducer, 3-5 parts of polypropylene fiber, 0.5-1.5 parts of a styrene acrylic emulsion, 1.5-5 parts of an organosilicon hydrophobic agent, 4-8 parts of a coagulant, 0.5-1.5 parts of sodium metaaluminate, 0.5-1.5 parts of an early strength agent, 1-3 parts of nano boron fiber, 1-3 parts of nickel nanowire and 1-3parts of a water repellent. According to the invention, the integrity and toughness of the product are significantly improved, the surface powdering phenomenon is significantly reduced, the compressive strength of the product can be significantly improved and the thermal conductivity is reduced, thus reaching the effect of efficient heat preservation.

Description

technical field [0001] The invention relates to the field of composite thermal insulation boards, more specifically, the invention relates to a novel cement-based particle blended non-combustible lightweight composite thermal insulation board and a processing method thereof. Background technique [0002] The rapid economic development has sharply increased human demand for energy, especially the depletion of non-renewable resources, leading to increasingly serious energy problems, and the energy crisis has attracted people's attention. Building energy consumption accounts for a large proportion of energy consumption. To alleviate the energy crisis, building energy conservation is an important aspect, and thermal insulation and energy-saving wall materials are the most important aspect of building energy conservation. At present, the building insulation materials commonly used in my country mainly include the following types: foam insulation materials, composite silicate ins...

AI Technical Summary

Problems solved by technology

When building energy-saving standards are increased by 75% and above, the thickness of thermal insulation materials for external wall insulation will increase greatly, posing a challenge to the safety of all external wall thermal insulation systems
