Abstract

The invention discloses an expanded perlite waterproof insulation board which is mainly composed of the following raw materials in percentage by weight: 40-60% of closed-pore expanded perlite, 20-30% of a CAS binding material, 15-25% of building bassanite, 10-15% of an active filler, and 2%-5% of a calcium stearate water-proofing agent, wherein the density of the closed-pore expanded perlite powder is 60-80kg/m<3>, needle-shaped wollastonite is adopted as the active filler, and the needle-shaped wollastonite has the granularity of 50-100 meshes. The expanded perlite waterproof insulation board has the beneficial effects that the expanded perlite waterproof insulation board is made of the ultralight closed-pore expanded perlite, the CAS binding material, the active filler and the like, and therefore, the expanded perlite waterproof insulation board has the mechanical properties of light weight, high strength and durability, and also has the characteristics of heat preservation, non-combustible property, water-proof property and the like.

Description

A kind of pearlstone water-proof heat-insulating slab
Technical field
The present invention relates to building material field, specifically a kind of pearlstone water-proof heat-insulating slab.
Background technology
The perlite water-proof heat-insulating slab is precious, pearl rock hydrophobic heat-insulating plate (claiming again the FSG water-proof heat-insulating slab), it is take the hydrophobic expansion pearlite bulk cargo as aggregate, the insulating water-proof warming plate that adds the operations such as water-resisting agent and binding agent are prepared, screening, extrusion forming, oven dry to make.The perlite water-proof heat-insulating slab it have that unit weight is light, good heat insulating, hydrophobic rate high (the hydrophobic rate can reach more than 98%), the advantages such as intensity is good, thermal conductivity is low, easy construction, unique hydrophobicity performance, overcome that other lagging materials make moist or trickle after the shortcoming that greatly reduces of its thermal and insulating performance.Perlite water-proof heat-insulating slab perlite hydrophobic heat-insulating plate is widely used in various insulations, cold insulation, the insulation contractors of roof, body of wall, freezer, silo and the vault of buildings.
Summary of the invention
The purpose of this invention is to provide a kind of pearlstone water-proof heat-insulating slab, the characteristics such as have lightweight, insulation, do not fire, and good water-proof effect.
Technical scheme of the present invention is achieved in that a kind of pearlstone water-proof heat-insulating slab, it is characterized in that, mainly by the raw material of following massfraction, is made:
Closed pore fine perlite 40~60%;
CAS gelling material 20~30%;
Building bassanite 15~25%;
Activity filler 10~15%;
Calcium stearate water-resisting agent 2~5%.
The density of described closed pore fine perlite is 60~80Kg/m 3.
Described activity filler is the acicular wollastonite powder.
The granularity of described acicular wollastonite powder is 50~100 orders.
Beneficial effect of the present invention is: pearlstone water-proof heat-insulating slab of the present invention is made by ultralight closed pore fine perlite, CAS gelling material, active packing material etc., have lightweight, high-strength, durable mechanical property, also have insulation, do not fire, the characteristic such as waterproof.
