Abstract
The invention relates to a method for manufacturing a glass bead polyurethane composite insulation board and belongs to the field of building materials. According to the insulation board, on the premise that the original insulation effect is maintained, fire resistance is improved, strength is improved, water absorption performance is lowered, and production cost is reduced. The method comprises the steps that glass beads and one of polyisocyanates and premixed polyether polyols are placed in a stirrer to be evenly stirred and mixed; the material obtained after even stirring and mixing and polyisocyanates or premixed polyether polyols are sprayed into a specific mold in proportion; the specific mold is slowly vibrated and pressurized, air needs to be discharged outside gradually during vibration and pressurization of the specific mold, generation of bubbles is reduced, and then the polyisocyanates and premixed polyether polyols are fully foamed to form polyurethane and the glass beads are squeezed and bonded, so that the board is formed finally; and the product, namely the glass bead polyurethane composite insulation board is separated from the specific mold.
Description
Technical field
The invention belongs to building material field, be specifically related to a kind of glass bead polyurethane composite heat-conservation board preparation method.
Background technology
Traditional warming plate, manufacturing process is mainly by passing into high temperature and high pressure steam, and after reaching the stipulated time, water filling has cooled.This insulation material shortcoming is that production cost is high, and fire protecting performance is low, seriously polluted, and heat insulation effect is not good.Along with more and more higher to the requirement of construction material, rigid polyurethane foam heat insulation material is slowly employed, but is not suitable for actual large-scale application because of its high cost.
In prior art, in polyurethane foam material, polyisocyanates is commonly called as pearl material, and combined polyether (polyalcohol) is commonly called as ester material, and by polyalcohol, fire retardant, catalyst, other auxiliary agents such as blowing agent mix.Glass bead is commercially available.
A kind of glass bead polyurethane composite heat-conservation board preparation method of the present invention is as follows:
1) by glass bead first with polyisocyanates or combined polyether wherein one put into agitator and be uniformly mixed;
2) material after being uniformly mixed in step 1) and polyisocyanates or combined polyether are sprayed in particular mold in proportion respectively;
3) slowly vibrate particular mold and pressurize, needing to discharge air outward gradually in particular mold vibration pressure process, reduce the generation of bubble, making polyisocyanates and combined polyether fully be foamed into polyurethane and extrude bonding glass bead finally to become plate;
4) products of separated from particular mold, is glass bead polyurethane composite heat-conservation board.
In described a kind of glass bead polyurethane composite heat-conservation board preparation method, the accounting of glass bead is 10% ~ 90%.
Preferably, the accounting of described glass bead is 30%.
Preferably, the accounting of described glass bead is 50%.
Preferably, the accounting of described glass bead is 70%.
In prior art, in polyurethane foam material, polyisocyanates is commonly called as pearl material, and combined polyether (polyalcohol) is commonly called as ester material, and by polyalcohol, fire retardant, catalyst, other auxiliary agents such as blowing agent mix.Glass bead is commercially available.
Summary of the invention
For solving the problem, main purpose of the present invention is to provide a kind of glass bead polyurethane composite heat-conservation board preparation method, while the original heat insulation effect of maintenance, also improves fire line, adds intensity, reduce water imbibition, reduce production cost.
