Abstract

An integral on-site spray-type water-resistant heat-insulating composite roof adopting rigid polyurethane foams belongs to constructional engineering roof components manufactured on site, and aims to provide an integral composite roof with the functions of no seams, water resistance, air permeability, heat preservation and heat insulation. A foamed rigid polyurethane foam insulation layer sprayed directly and a water-resistant ventilated membrane laid on the insulation layer directly are combined so as to form the integral water-resistant heat-insulating roof, and the water-resistant ventilated membrane is a high molecular ventilated thin film added with hydrophilic group. The integral on-site spray-type water-resistant heat-insulating composite roof solves the difficult problem of leakage of the roof; the integral on-site spray-type water-resistant heat-insulating composite roof is convenient to construct, achieves good operation random and long use time, and can fully cover anisotropic surfaces, plane junctions and concave and convex corners; the integral on-site spray-type water-resistant heat-insulating composite roof has very strong cohesive force to metal, concrete, masonry, timber, glass, fibers and the like; and a conventional water-resistant layer and a conventional heat-insulating layer do not need to be eradicated and marked dust, sand and sundries need to be removed only so as to perform the spraying when the integral on-site spray-type water-resistant heat-insulating composite roof is applied to new and old roofs.

Description

Integral body is sprayed the waterproof thermal-insulated composite roof of hard polyurethane foams at present
Technical field
The utility model relates to a kind of construction work roofing element of making at the scene.
Background technology
Existing polyurethane foamed material can only be used for the thermal insulation of pipeline and freezer owing to lack water resistance; When roofing was used, present way was a making cement mortar cover on polyurethane foam, or did topping with water-repellent paints such as acrylic acid, neoprenes.Topping durability with cement mortar is made is bad, is easy to generate shrinkage crack and aging seepage phenomenon.And the topping gas permeability that adopts water-repellent paints such as acrylic acid, neoprene to do is bad, is not easy to the circulation of air in room, and roofing is also multiplied mould easily.
The utility model content
The purpose of the utility model provides a kind of integral body and sprays the waterproof thermal-insulated composite roof of hard polyurethane foams at present, and it is simple in structure, integral seamless crack, good airproof performance, waterproof thermal-insulated effective.
The purpose of the utility model realizes as follows: this integral body is sprayed the waterproof thermal-insulated composite roof of hard polyurethane foams at present; With the RPUF is insulation layer, and the technical scheme of employing is with the RPUF insulation layer of direct spray coating foaming and directly is layered on the integrated water-proof heat insulation roofing of waterproof ventilated membrane on the insulation layer.
Above-mentioned waterproof ventilated membrane is to pass through in the vapour film at macromolecule to have added hydrophilic group.
The beneficial effect of the utility model is: this roofing good integrity, and no seam, sound-absorbing, anti-seismic performance are good; Coefficient of thermal conductivity is low, and 2.5 kilograms/mk of compressive strength meets the technical requirements of " civilian construction thermal performance design rules " JGJ24-86 fully; Roofing thickness is merely 1/3rd of traditional roofing; But calorific value increases about two times, can alleviate the about 50-100 kilogram of roofing load/square metre, the insulation, heat insulation, effect is remarkable; The fine-celled foam body that this product insulation layer is a compact structure; Rate of closed hole reaches more than 92%; Its top layer can guarantee that from skinning and water-repellent paint topping roofing is waterproof fully, once accomplishes basal plane engineering waterproofing, insulation, heat insulation construction, has solved the difficult problem of roof seepage; Easy construction, the operation randomness is good, all can cover different in nature face, plane intersection, each position, negative and positive angle comprehensively; Service time is long; Metal, concrete, masonry, timber, glass, fiber etc. there are very strong adhesion stress, can be applicable to newly, during old roof; Needn't root out original waterproofing course and insulation layer, can spray as long as remove dust and sand, the foreign material indicated.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model.
The specific embodiment:
With reference to accompanying drawing; This integral body is sprayed the waterproof thermal-insulated composite roof of hard polyurethane foams at present; With the RPUF is insulation layer, and it is with the RPUF insulation layer of direct spray coating foaming and directly is layered on the integrated water-proof heat insulation roofing of waterproof ventilated membrane on the insulation layer.Described waterproof ventilated membrane is to pass through in the vapour film at macromolecule to have added hydrophilic group.Earlier that the roof base cleaning is clean during use, to the roofing of precast floor slab, plate supported end and the position of seepage easily, with sticking empty shop of 20-30cm coiled material point,, also can carry out waterproofing work with waterproof roll earlier earlier to giving prominence to parapet, the pipeline root of roofing.Then with A component polyalcohol and B component polyisocyanates mix in proportion, with professional spray gun spray coating heat preservation layer, treat the heat-insulating layer foaming coagulation forming after, repave waterproof ventilated membrane, process integral body and spray the waterproof thermal-insulated composite roof of hard polyurethane foams at present.

Claims (2)

1. an integral body is sprayed the waterproof thermal-insulated composite roof of hard polyurethane foams at present; With the RPUF is insulation layer, it is characterized in that: be with the RPUF insulation layer of direct spray coating foaming and directly be layered on the integrated water-proof heat insulation roofing of waterproof ventilated membrane on the insulation layer.
2. integral body according to claim 1 is sprayed the waterproof thermal-insulated composite roof of hard polyurethane foams at present, it is characterized in that: said waterproof ventilated membrane is to pass through in the vapour film at macromolecule to have added hydrophilic group.
