Abstract

The present invention relates to a hard polyurethane foam plate composite energy-saving wall and a construction process thereof. The present invention can mainly solve the problem that empty bulging, falling and cracking are easily generated to glue powder polyphenyl particles, expansion polyphenyl plates, etc. in the existing heat insulation wall of a building outer wall. The present invention can meet the targets of 65% of construction energy saving and effective utilization of waste and old polyurethane foam materials and solve the problem of environment pollution of the polyurethane foam materials. After a base layer wall is treated, an interface layer is orderly coated. A concave hard polyurethane foam heat insulation plate is fixed by a plastic anchoring element. Concave parts are cast and sprayed by hard polyurethane foam materials on site to form an adhesive heat insulation layer. Elastic anti-crack putty is compounded with a polyethylene hole net to form an anti-crack protecting layer. Finally, a decorative surface layer is made. The present invention finds an outlet for the waste polyurethane foam materials, and the hard polyurethane foam heat insulation plate with the excellent thermal work performance is formed by composition. The problems that thickness can not be easily controlled, and a surface is rough and uneven when hard polyurethane foam is sprayed on site are solved. The present invention finds materials with high quality and a low price and construction technology for 65% of energy saving for the third step of construction.

Description

Hard polyurethane foam board composite energy-saving wall and construction technology thereof
Technical field
The present invention relates to building energy conservation body of wall and job practices thereof.
Background technology
The existing building external-wall heat-insulation material has just solved 50% building energy conservation problem, and the low inferior drawback of cracking, infiltration, cavity, hollowing and thermal property occurs because of the restriction of various factors causes energy-saving wall; Because polyurethane products are widely used among the every field in national economy and the people life, a large amount of discarded polyurethane foams occur; The job practices of in-situ spraying polyurethane foam is because the bad control of thickness makes its rough surface.How to improve the building exterior wall heat preserving thermal property on the one hand, make full use of discarded polyurethane foamed material on the other hand, solve the environment pollution and the high-effective building energy-saving problem of its generation, people are always in constantly exploring.
Summary of the invention
The object of the present invention is to provide a kind ofly can make full use of discarded polyurethane foamed material and can produce the good construction material of thermal property again, thereby guarantee the thermal property and the construction works quality of construction wall energy-conservation 65%.
Purpose of the present invention is realized by following scheme:
A kind of hard polyurethane foam board composite energy-saving wall, it comprises body of wall basic unit 1, interfacial agents layer 2 and outer field finish coat 8 after the processing, it is characterized in that: the outer setting at interfacial agents layer 2 has spill hard polyurethane foams warming plate 4, form heat insulation cementing layer 3 to its spill position spraying cast polyurethane rigid foam, and form the cracking resistance overcoat with elastic water-proofing material 6 composite polyethylene hole patterns 5.
Above-mentioned spill hard polyurethane foams warming plate 4 is by discarded poly-ammonia foam powder, aluminium powder, hollow glass micropearl, polyurethane adhesive 80: 3: 8 in proportion: 9 mix after the female moulded from foam forms.
Above-mentioned interfacial agents layer 2 is to be mixed at 1: 1 in proportion by polyurethane prepolymer and epoxy resin.
Waterproofing materials 6 in the above-mentioned cracking resistance overcoat be by aqueous elastic polyurethane resin and cement in proportion 1: 2 compound formulated.
Composite polyethylene hole pattern 5 in the above-mentioned cracking resistance overcoat is injection molded through injection machine with the mesh mould by polyethylene.
A kind of construction technology of hard polyurethane foam board composite energy-saving wall, include processing, brushing interfacial agents layer 2 to body of wall basic unit 1, unique distinction is: at interfacial agents layer 2 brushing back fixedly spill hard polyurethane foams warming plate 4 of plastics crab-bolt 7, form heat insulation cementing layer 3 to spill position spraying cast polyurethane rigid foam again; Be compounded to form the cracking resistance overcoat with polyethylene hole pattern 5 and elastic water-proof putty 6, do finish coat 8 at last.
Above-mentioned spraying cast polyurethane rigid foam forms heat insulation cementing layer 3, its method is that the performed polymer behind the isocyanates prepolymerization reaction is weighed into capping in the jar, seal the back and under the situation of pressurization, (add blowing agent as 3~4Mpa), open valve during spraying, foam-like penetrates thing and promptly may be cast in the spill position of warming plate 4, and then solidify to form heat insulation cementing layer 3.
Advantage of the present invention: discarded polyurethane foam material can be turned waste into wealth and make spill rigid polyurethane foams heat preservation energy-saving board (coefficient of thermal conductivity is 0.028K/MK), for realizing that building energy conservation 65% has found economical and practical heat insulating material, form the building energy conservation walling system that does not ftracture, do not have cavity, no hollowing.Efficiently solve problem of environmental pollution, improved the construction wall thermal property, shortened the engineering construction duration and guaranteed workmanship.
