Abstract
The present invention relates to waterproof heat insulating material, and is especially one kind of hard waterproof heat insulating foamed polyurethane material. The hard waterproof heat insulating foamed polyurethane material consists of two components, including component A in 100 weight portions and component B in 120-130 weight portions. During construction, these two components are mixed and sprayed with compressed air in the spraying apparatus in the environment temperature of 10-35 deg.c. The present invention has the advantage of fast construction, and once the hard waterproof heat insulating foamed polyurethane material is sprayed, one light waterproof heat insulating layer is formed.
Description
Technical field
The present invention relates to a kind of water-proof heat-insulation material, particularly a kind of polyurethane hard bubble water-proof thermal insulation material.
Background technology
Waterproof and heat-insulating at building roof mainly is to adopt traditional thermoplastic liquid matrix material coating at present, film applying immobilization material and powder knot material mixing are used, as use pitch, waterproof cloth, cement perlite, cement vermiculite, but its waterproof thermal-insulated function of traditional material has unicity, it is waterproof thermal-insulated to be respectively to be different materials, the difficulty of waterproof construction is bigger, at first need working face is carried out can constructing behind the mortar levelling, in the processing of some seams and thin portion, need to lay disappointing groove, vapor pipe, particularly then difficulty is bigger at the odd-shaped roofing construction, and the rimose phenomenon takes place later on easily, waterproof effect is undesirable.And its density of the material of heat-insulation and heat-preservation is the highest in 500～600 kilograms per cubic meter, and the building roof has been increased very big load; And the conventional waterproof material generally just needed overhaul again, so traditional water-proof heat-insulation material can't satisfy the demand of modern architecture in 3～5 years.
Summary of the invention
The technical issues that need to address of the present invention are to disclose a kind of polyurethane hard bubble water-proof thermal insulation material, to overcome the above-mentioned defective that existing utilisation technology exists.
Polyurethane hard bubble water-proof thermal insulation material of the present invention comprises the A component of 100 weight parts and the B component of 120～130 weight parts, and preferred B ingredients weight parts is 125 parts, and weight percent consists of:
