Heat preservation waterproof composite coiled material suitable for roof transformation and preparation method thereof

Abstract

The invention provides a heat preservation waterproof composite coiled material suitable for roof transformation and a preparation method thereof. The composite coiled material comprises a heat preservation and heat insulation core material, a non-woven fabric reinforced breathable film and a base layer protective film which are fused into a whole in a spot shape or a strip shape by using a hot-melt pressure-sensitive adhesive. The heat preservation and heat insulation core material is silica aerogel felt; the non-woven fabric reinforced breathable film is formed by stacking non-woven fabricson the upper and lower sides of a polyethylene film through hot-melting and direct-pressing; the base layer protective film is a steam-insulating film. The composite coiled material has the advantagesof achieving A grade fire prevention and being high in heat preservation and heat insulation property, high in air permeability and water resistance, light, flexible, high in deformation resistance and convenient to construct, the coiled material is especially suitable for existing house roof updating and transformation, the roof transformation and construction technology is simplified, the transformation and construction speed is increased, and the environment friendliness, energy conservation and use durability of a roof are greatly improved.

Description

technical field [0001] The invention relates to the technical field of roof renovation of existing houses, in particular to a novel thermal insulation and waterproof composite coil suitable for renovation of existing roofs, and a preparation method thereof. Background technique [0002] Roof is an important enclosure structure of existing houses, and it is also an important part of building energy-saving optimization. On the basis of ensuring structural safety and durability, the renovation of existing houses attaches great importance to the green and energy-saving roofs. At present, in the renovation of the roof of existing houses, the thermal insulation layer is generally made on the roof truss structure, and then the waterproof layer and protective layer are made on the upper part. This method not only has cumbersome construction techniques, slow progress, and large space usage, but also the separate structure is prone to cross-effects, leading to aging and damage of mat...

AI Technical Summary

Problems solved by technology

[0004] However, relevant research or patent results are difficult to apply to existing house sloping roofs, especially tile roofs. The main problems include: 1) There is a problem of airgel powder detachment in the use stage of silica airgel materials, and long-term exposure will cause 2) The sloping roof structure is generally composed of purlins, rafters, and hanging mesh bars, etc. It is difficult to use rigid materials effectively, so flexible materials should be used to facilitate laying and maintenance; 3 ) The roof truss is a space structure formed by the connection of rods, which is deformed by external factors, and the thermal insulation and waterproof materials should have good deformation coordination ability; 4) The roof thermal insulation and waterproof treatment can improve energy saving and avoid condensation and frost At the same time, consider preventing the penetration and erosion of water vapor on the roof of the building, and improving the durability of the material by improving the material's air permeability
