Heat-insulation and fire-resistant composite plate based on rock wool belts as core materials and processing technology thereof

Abstract

The invention relates to the technical field of rock wool product belts, in particular to a heat-insulation and fire-resistant composite plate based on rock wool belts as core materials and a processing technology thereof. The heat-insulation and fire-resistant composite plate comprises a base layer wall plate, the outer wall of one side of the base layer wall plate is evenly coated with construction adhesive, a heat-insulation rock wool plate is fixedly bonded to the base layer wall plate through the construction adhesive, the outer layer of the side, far away from the base layer wall plate,of the heat-insulation rock wool plate is evenly sprayed with protective mortar through a spray gun, and the outer layer of the protective mortar is provided with glass fiber mesh cloth. The heat-insulation and fire-resistant composite plate has the beneficial effect that high-quality basalt is used as a main raw material, after later melting, an international advanced four-roll centrifugal cotton-making process is adopted, high-temperature melt of the basalt is thrown and drawn into discontinuous fibers being 4-7 microns, a certain number of binders, dust-proof oil and water-repellent agentsare added into rock cotton fibers, processes such as sedimentation, curing and cutting are carried out, a series of products with different densities are made according to different purposes, and thecharacteristics of heat insulation, heat preservation, sound absorption, noise reduction, good non-combustion fire-resistant and temperature-resistant performance, long service life and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of rock wool product belts, in particular to a thermal insulation and fireproof composite board based on rock wool belts as a core material and a processing technology thereof. Background technique [0002] Rock wool is made of high-quality basalt, dolomite and other main raw materials. After being melted at a high temperature above 1450 ° C, it is centrifuged at high speed by an internationally advanced four-axis centrifuge to form fibers. At the same time, a certain amount of adhesive, dust-proof oil, and tax-increasing agent are sprayed. Rock wool products of different specifications and uses are formed after being collected by a cotton collector, pendulum method, and three-dimensional method for laying cotton and then solidified and cut. Rock wool composite board has the characteristics of light weight, small thermal conductivity, heat absorption, and non-combustibility, so it is widely used in heat insu...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a thermal insulation and fireproof composite board based on rock wool tape as the core material and its processing technology, to solve the unreasonable production process of the existing thermal fireproof composite board proposed in the above background technology, poor product characteristics, There is a complex structure when installing on the wallboard, which not only increases the thickness of the wall, but also has the problem of poor stability during installation
