Production method of inorganic fiber roof heat-insulation waterproofing system

Abstract

The invention discloses a production method of an inorganic fiber roof heat-insulation waterproofing system. The roof top is paved with the heat-insulation waterproofing system; the method comprises following steps: the roof top is sprayed and covered by inorganic fiber and binder synchronously and uniformly; the inorganic fiber is output by a blower fan; the binder is synchronously sprayed and attaches to the surface of the inorganic fiber where the inorganic fiber is sprayed out; the inorganic fiber is bonded to the roof top by means of the binder to form an inorganic fiber layer; after the inorganic fiber layer on the roof top is solidified and set, binder is uniformly sprayed on the surface; non-woven fabrics is attached to an upper surface of the inorganic fiber and is bonded with the inorganic fiber layer surface by means of the binder; a waterproofing layer is paved on the surface of the non-woven fabrics and waterproofing paint is sprayed on the waterproofing layer. The invention relates to the field of buildings. The invention discloses a production method which can substantially improve the heat insulation performance of the roofing and achieve integrated waterproofing and lightening.

Description

technical field [0001] The invention relates to the field of construction, in particular to a method for manufacturing an inorganic fiber roof heat preservation and waterproof system. Background technique [0002] At present, my country's building energy consumption accounts for about 1 / 3 of the total energy consumption of the whole society. The living area of ​​heating cities in northern my country only accounts for 10% of the national urban living area, but building energy consumption accounts for 40%. The largest energy consumption of buildings in our country is heating and cooling. Compared with developed countries with similar climate conditions, the heating energy consumption per square meter of buildings in our country is about three times that of developed countries. my country is currently making every effort to promote building energy saving by 65%. standard. [0003] Therefore, the thermal insulation performance of the original building is extremely poor, and the ...

AI Technical Summary

Problems solved by technology

[0003] Therefore, the thermal insulation performance of the original building is extremely poor, and the energy consumption is too large. It is necessary to carry out thermal insulation and energy-saving renovation. One of the simple and effective means is external thermal insulation

However, due to lessons learned from the CCTV fire, the application of low-cost organic insulation materials such as expanded polystyrene, expanded polyurethane, and expanded phenolic formaldehyde in building insulation has been greatly restricted, among which flame retardancy and fire resistance are fatal flaws

[0004] For example, technologies such as CN201410579889.3 use cement-based thermal insulation and waterproofing. On the one hand, too much self-weight is not conducive to the load bearing of buildings. On the other hand, the long cement maintenance cycle is not conducive to construction efficiency, and its thermal insulation effect is poor.

Organic thermal insulation materials such as polyurethane, polystyrene and other foaming materials have the defect of poor fire resistance; among inorganic thermal insulation materials, such as rock wool board or rock wool felt, they are easy to absorb moisture and fall off after long-term use, and foamed perlite and foamed ceramics , foamed glass, foamed cement, etc. have poor thermal insulation effects, and there are seam thermal bridges caused by multiple pieces of splicing, which leads to a decrease in thermal insulation effect
