Abstract

The invention provides a calcium silicon sandwich panel which is formed by processing and pasting two panel surfaces and sandwiched materials or filling by a way of sandwich, while the panel surface uses a calcium silicon panel, the sandwich uses a polyurethane plate formed by foaming the polyurethane under high pressure, wherein, the polyurethane plate can be made by melting polyester polyol which then reacts with a proper amount of isocyanate for 3-4 hours under low temperature, and then a catalytic and foaming agent is added in, thereby, the calcium silicon sandwich panel has well-behaved fireproof performance, whereas the polyurethane sandwich can also keep the chemical and the mechanical properties of the plank stuff stable, thus, the plank stuff has long service life.

Description

A kind of silico-calcium filled board
Technical field
The present invention relates to a kind of thermal insulating composite panel, especially fire-type heat preservation composite wall plate.
Background technology
Mostly present thermal insulating composite panel is to adopt polyvinyl chloride sandwich, on fireproof performance, just decrease like this, and the chemical weathering ageing properties compares comparatively fast, be not suitable in the abominable outside environment for use of exterior wall, otherwise application life is lower, improves the engineering cost.
Summary of the invention
The invention provides a kind of combined wall board that can improve fire-protection rating, improve ageing resistace.
For achieving the above object, technical scheme of the present invention is:
A kind of silico-calcium filled board, by two plate faces and sandwich material cohere processing or sandwich filling form, it is characterized in that the plate face adopts calcium silicate board with microporous, the polyurethane plate that sandwich employing polyurethane foams under high pressure conditions and forms, wherein the polyurethane plate can be by PEPA fusing and an amount of isocyanates low-temp reaction 3-4 hour, adds catalysis then and blowing agent is made.
The silico-calcium filled board has excellent fireproof performance like this, and the sandwich chemistry and the stable mechanical property that can keep sheet material of polyurethane makes sheet material possess good application life.
The specific embodiment
In concrete the enforcement, mostly calcium silicate board with microporous is that adopting silicate is raw material, and to adopt other chopped strands be that aggregate improves plate surface tension force.
Secondly, calcium silicate board with microporous can be made into a plurality of continuous " worker " fonts, carries out the foaming of polyurethane in inside, so also can form firm prestressed structure.
In addition, in actual production, because polyurethane foam is difficult to reclaim, wastage of material is big, generally takes advanced technologies, can save material and reduce cost.
After general office premises adopts the sandwich sheet material of silico-calcium to carry out wall decoration, its trimming cost is a shade below decoration of exterior wall costs such as ceramic tiles, save the electric energy loss about 70% that air-conditioning brings in the use but heat-insulating property makes, improve 20～30% application life, and easy to clean.

Claims (3)

1. silico-calcium filled board, by two plate faces and sandwich material cohere processing or sandwich filling form, it is characterized in that the plate face adopts calcium silicate board with microporous, the polyurethane plate that sandwich employing polyurethane foams under high pressure conditions and forms, wherein the polyurethane plate can be by PEPA fusing and an amount of isocyanates low-temp reaction 3-4 hour, adds catalysis then and blowing agent is made.
2. according to claim 1, it is characterized in that it is raw material that calcium silicate board with microporous adopts silicate, and to adopt other chopped strands be that aggregate improves plate surface tension force.
3. according to claim 1, it is characterized in that calcium silicate board with microporous can be made into a plurality of continuous " worker " fonts, carries out the foaming of polyurethane in inside.
