Abstract

The composition of water-proof heat-insulating board using expanded perlite as aggregate comprises (wt%) 45-50% of perlite powder, 5-7% of water, 35-42% of water-glass, 4-6% of hardening agent, 1.5-2.5% of water-proof agent and 1.3-2% of adhesive, and its production process includes the procedures of proportionning, stirring, compacting and drying. Said invented water-proof perlite heat-insulating board features light weight, low thermal conductivity, strong water-resistance, stable quality, low cost, and can be cut into required shape and size.

Description

A kind of water-proof pearlite heat-insulation plate
The invention belongs to building material field, particularly a kind of roofing, wall heat insulation material.
Existing roofing heat insulating material kind is more, and wherein pearlite heat-insulation plate is little because of having density, and thermal conductivity hangs down advantages such as reaching sound insulation, is that many buildings adopt." the heat insulating sandwich material " utility model patent (notification number CN2037759U) of Patent Office of the People's Republic of China's bulletin on May 17th, 89 is to be wrapped in the plastics film by diffusing shape perlite to make, and some sandwich material permutation and combination form the building laminboard layer together.This sandwich of layers has heat insulation effect preferably, is easy to construction, but yielding in the carrying, wearing and tearing, and waterproof effect is relatively poor, influences construction quality.
The objective of the invention is weak point, the pearlite heat-insulation plate of a kind of good waterproof performance, intensity height, good effect of heat insulation is provided at existing pearlite heat-insulation plate.
Product of the present invention is to be aggregate with the pearlstone, adds waterproof, gelling material, makes through proportioning, stirring, compacting, baking operation.Composition weight percent of the present invention is: perlite powder 45-50%, water 5-7%, water glass 35-42%, accelerator for hardening 4-6%, water-resisting agent 1.5-2.5%, tackiness agent 1.3-2%.With the perlite ore sieving and grading, high temperature preheating, volumetric expansion becomes white or the neutral inorganic shape perlite powder of grey; Stir after ratio is mixed with accelerator for hardening and tackiness agent on request with perlite powder earlier, add water glass, water-resisting agent and water again, after the mixing and stirring, compaction moulding after filtration,, finished product is sent into High-temp. kiln kiln discharge after oven dry in 24 hours after airing, curing, get product.
The present invention has the advantages that unit weight is light, thermal conductivity is little, water-repellancy is strong, and profile side is whole can to cut, and steady quality, cheap is industry and covil construction roofing and the heat insulation ideal material of wall thermal insulating.
Embodiments of the invention are as follows:
The material mixture ratio of this warming plate is pressed m 3/ 1 calculates: perlite powder 150kg accounts for 47.5% of total amount, water (H 2O) 20kg accounts for 6% of total amount, water glass (H 2ONSiO 2) 120kg, accounting for 38% of total amount, water-resisting agent 6kg accounts for 1.9% of total amount, and tackiness agent 5kg accounts for 1.6% of total amount, accelerator for hardening (Na 2SiF 6) 15kg, account for 5% of total amount.The composition of water-resisting agent is a potassium silicon aldehyde sodium, and the composition of tackiness agent is a polyvinyl formal.
The working method of this warming plate is:
1. the method for making of pearlstone: with perlite ore screening, classification, high temperature preheating.Volume expands suddenly, and to become the inorganic sand shape of a kind of white or gray neutrality be swelling perlite powder.
2. the method for making of water glass: quartz sand and caustic soda being used steam heating in pressure kettle, directly be dissolved into liquid, is the best with water white thick liquid nano water glass.
Pearlstone with suitable particle diameter is an aggregate, adds water glass, water glass and airborne CO 2Effect is analysed and is disengaged SiO 2Gel; for accelerating reaction process; the Sodium Silicofluoride accelerator for hardening of adding 5%; add water-resisting agent, water and tackiness agent in proportion; again after mixing, with motor-vibro screen filtration, high-strength press molding machine compaction moulding, after finished product process airing, the curing; send in the High-temp. kiln after oven dry in 24 hours, to go out, get product.Production Flow Chart is: press m 3/ 1 calculates per-cent batching → motorized pulleys stirrer stirs → filters → high-strength press molding machine compaction moulding → airing → and send 24 hours → kiln discharge of High-temp. kiln oven dry → finished product packing warehouse-in to stack.

Claims (3)

1. a water-proof pearlite heat-insulation plate is characterized in that this warming plate composition weight percent is: perlite powder 45-50% water 5-7% water glass 35-42% accelerator for hardening 4-6% water-resisting agent 1.5-2.5% tackiness agent 1.3-2%.
2. a kind of water-proof pearlite heat-insulation plate according to claim 1 is characterized in that the working method of this warming plate is: with the perlite ore sieving and grading, and high temperature preheating, volumetric expansion becomes white or the neutral inorganic nature perlite powder of grey; Stir after ratio is mixed with accelerator for hardening and tackiness agent on request with swelling perlite powder earlier, add water glass, water-resisting agent and water again, after the mixing and stirring, compaction moulding after filtration,, finished product is sent into High-temp. kiln kiln discharge after oven dry in 24 hours after airing, curing, get product.
3. according to claim 1 and 2 described a kind of water-proof pearlite heat-insulation plates, it is characterized in that said accelerator for hardening is Sodium Silicofluoride (Na 2SiF 6), water-resisting agent is a potassium silicon aldehyde sodium, tackiness agent is a polyvinyl formal.
