Description
Technical field
The present invention relates to building material technical fields, especially a kind of for for replacing cement to build a wall as construction material
When the polyurethane adhesive that uses.
Background technique
Cranny filler of polyurethane foam is commonly called as foaming agent, PU gap filler, is a kind of one pack system, moisture-curable, multiduty poly-
The foam filled elaxtic seal of urethane is that the components such as Ju urethane Yu Ju Ti ﹑ Fa Pao Ji ﹑ catalyst are loaded on pressure-resistant inhalator jar
In special polyurethane products.Mist colloid is sprayed to portion to be onstructed by mating applicator gun or manual jet pipe when construction
Position, the polyurethane materials of foam shape, which are expanded rapidly and are cured with the moisture in air or the matrix touched, reacts formation bubble
Foam completes molding, foaming, bonding and seal process short-term, and solidification foam elastomer has bonding, waterproof, resistance to heat expansion cold
Excellent performances, the filling being widely used at building doors and windows side seam, member expansion joint and hole such as contracting, heat-insulated, sound insulation, fire-retardant are close
Envelope, energy conservation and environmental protection are easy to use；However, most of cranny filler of polyurethane foam are also only used as gap filler at present.
In building field, construction worker during building a wall, be all be sufficiently stirred using a certain proportion of water and sand it is mixed
The wall of building is formed after closing uniformly for being bonded brick.And in the process, since cement self weight and volume are larger,
Whipping process is not only time-consuming and laborious, and construction worker's large labor intensity, brings larger inconvenience to construction and use.In addition, water
Requirement of the mud as current construction walling, production also bring along biggish pollution, cause larger pressure to environmental protection.
Although cranny filler of polyurethane foam has binding function, mainly use joint filling, thus its coefficient of foaming compared with
The foam of height, generation is more, and the coefficient of expansion is very big, carries out operation of building a wall if be directly used in instead of cement, when construction
It is unable to control the uniformity of building masonry wall, wall crack also reduces greatly adhesive strength because of foam volume, and can not also protect
Demonstrate,prove the stability of building.
Chinese formerly application for a patent for invention 2016103658322 discloses a kind of polyurethane adhesive glue and replaces cementitious sand
The application of the bonding and thermal insulation material on exterior walls of buildings is starched, although proposing instead of cementitious mortar, the viscoelastic polyurethane
It connects glue and is also only applicable to the bonding and thermal insulation layer on exterior wall, equally exist the generally existing foaming times of conventional polyurethane foams gap filler
The problem that number is high, the coefficient of expansion is big, is not used to the use of building a wall of construction.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of for substituting poly- ammonia of the cement as proprietary material of building a wall
Ester gum and its application can reduce the construction time on the basis of guaranteeing to build physical performance, reduce labor intensity and be constructed into
This.
In order to solve the above technical problems, the technical solution used in the present invention is as follows.
One kind is built a wall with polyurethane adhesive, and the component of following parts by weight is specifically included:

Wherein, in white material include following weight percentage component: 30% polyether polyol 310,30% polyether polyol 210,
The even bubble silicone oil of 10% polyether polyol 5631,2.5%, 1% brokenly bubble silicone oil, 1.3% dual-morpholinyl diethyl ether, 25.2% chlorinated paraffin；
Black material is polymethylene multi-phenenyl isocyanate.
Above-mentioned one kind is built a wall with polyurethane adhesive, and the viscosity of the chlorinated paraffin is 600(50 DEG C) mpa.s.
A kind of application built a wall with polyurethane adhesive, the polyurethane adhesive are applied to building for frame construction inner partition wall
Cheng Zhong, it is first that the brick body upper surface for needing to be bonded is clean, and a small amount of water is sprayed, keep bonding plane wet；Secondly it takes out
Polyurethane glue bottle level is installed in dedicated glue rifle after shaking up；Then wet brick body upper surface is glued；Then immediately will
Another brick body is placed in the lower layer's brick body for applied glue and compresses.
Due to using above technical scheme, the invention technological progress is as follows.
The dedicated wall bonding agent that the present invention is used as non-bearing wall body inside building constructure, have take use,
The easy advantage of light-weight, construction is simple, operation replaces cement to carry out the construction of construction wall using the present invention, and one bottle 900
Gram polyurethane adhesive can bond area about 5m2Wall, or so construction time about half an hour not only reduces the construction time, drops
Low construction cost and construction worker's labor intensity；Simultaneously because cement can be substituted completely, therefore it is raw also to avoid cement
There are the appearance of problem of environmental pollution for production.
Main component of the invention uses conventional polyether polyalcohol and polymethylene multi-phenenyl isocyanate, but to by gathering
The white material that ethoxylated polyhydric alcohol is constituted has carried out the stringent proportion of component, and is added to even bubble silicone oil and brokenly bubble silicone oil, and by new
Increase the restriction of weight percentages of components, so that polyurethane adhesive, when being sprayed on wet construction surface, moment completes by hair
The process of bubble and brokenly bubble, the effect of binding component medium-high viscosity chlorinated paraffin had both limited its coefficient of foaming, while being also provided with
High viscosity and high-strength characteristic, so that the building masonry wall finished building both maintains intensity, it may have preferable uniformity, reliably
It ensure that the stability of building.
