Inorganic composite polyphenyl A level heat-preserving plate

Abstract

The invention discloses an inorganic composite polyphenyl A level heat-preserving plate. A heat preserving plate body is included, and comprises a common polystyrene plate blank material and a cement-based inorganic fireproof material; the cement-based inorganic fireproof material makes a cement-based inorganic fireproof pulp-shape material uniformly permeate to the position around polystyrene particles and wrap the position around the polystyrene particles, and a honeycomb-shaped supporting framework structure is formed; and the homogenous inorganic composite polyphenyl A level heat-preserving plate is formed due to moisture preserving and maintaining curing in one stage.

Description

technical field [0001] The invention relates to the field of construction equipment, and more precisely, the invention relates to an inorganic composite polystyrene grade A insulation board and a production method thereof. Background technique [0002] It is well known that fires broke out in Shanghai and Shenyang because of thermal insulation materials, but the direct cause of the fire was sparks generated by workers welding steel keels when dry-hanging stone materials. In fact, thousands of insulation board fires occur every year due to electric welding. The insulation materials used are polystyrene boards, extruded boards, polyurethane, phenolic boards, real gold boards, etc., and their fire ratings are Class B. In addition, many domestic insulation walls that have been completed have problems with the insulation layer falling off. One of the reasons is that the ability to stain dust is insufficient. The second is that the thermal expansion and contraction coefficient of...

AI Technical Summary

Problems solved by technology

The disadvantage is that all organic materials have poor fire resistance, which is Class B fire resistance. The thermal expansion and contraction coefficients of organic materials and inorganic cement mortar have a large gap and insufficient bonding ability, which is prone to falling off.

The second type is inorganic material insulation board, rock wool insulation board is widely used, its advantages are good fire resistance and moderate insulation performance, its disadvantage is that rock wool is made of pressed, loose structure, poor tensile performance, loose structure absorbs water High rate will easily lead to loss of heat preservation effect due to water absorption, insufficient ash sticking ability, easy weathering, short service life, and shedding phenomenon
