Problems solved by technology

[0002] The treatment of the roof surface in house construction is essential, among which waterproof and heat insulation is a problem that must be solved. At present, the solution to waterproof and heat insulation is mostly to use linoleum and asphalt to cover the roof surface to prevent water and leaks. Heat insulation, this treatment method sometimes has poor waterproof effect, short service life, frequent maintenance, high cost of double-layer construction, troublesome construction, unsatisfactory heat insulation effect, and asphalt roof surface pollutes the environment, which is not conducive to Environmental protection, therefore, the treatment of asphalt roof surfaces is not welcomed

Embodiment Construction

[0004] The specific implementation of the present invention will be described in detail below in combination with specific situations.

[0005] The present invention adopts two layers of white non-woven fabrics and the polyethylene film of the middle layer to be heat-pressed, and sprays and paints the bottom layer, the middle layer and the surface layer on them. The specific production method is to add a layer of polyethylene film between two layers of non-woven fabrics and heat press them together at 180°C. 0.3-0.4 kg per square meter, middle material is 0.3 kg per square meter, and fabric is 0.3-0.4 kg per square meter. The base material is made by mixing 10 kg of emulsion, 6 kg of mother liquor and 84 kg of water. The medium material is made by stirring 30 kg of emulsion, 12 kg of mother liquor, 25 kg of light calcium carbonate, 2.5 kg of light magnesium oxide, 35 kg of water and 0.6 kg of dispersant, and then adding 0.2 kg of defoamer; the fabric is 40 kg of emulsion, 10 ...

Abstract

A heat-isolating water-proof coiled material for roof is prepared from two non-woven cloth layer and a central polyethene film layer through hot pressing, and coating priming material, central material and surface material, which contain emulsion, mother liquid, water and relative materials.

Description

1. Technical field [0001] The invention relates to a production method of a waterproof and heat-insulating coiled material used in building construction. 2. Background technology [0002] The treatment of the roof surface in house construction is indispensable, among which waterproof and heat insulation is a problem that must be solved, and the current solution to waterproof and heat insulation is mostly to use linoleum and asphalt to cover the roof surface to prevent water and leaks, and the top surface is double-layered or above. Heat insulation, this treatment method sometimes has poor waterproof effect, short service life, frequent maintenance, high cost of double-layer construction, troublesome construction, unsatisfactory heat insulation effect, and asphalt roof surface pollutes the environment, which is not conducive to Environmental protection, therefore, people do not welcome the treatment of asphalt roof surface. 3. Contents of the invention [0003] In view of ...
