Abstract
The invention discloses high-strength polyurethane construction glue and a preparing method thereof. The high-strength polyurethane construction glue is prepared from, by mass, 36-44 parts of isocyanate, 38-45 parts of chloroprene rubber, 2-3 parts of zinc chloride, 2-3 parts of magnesium chloride, 2-3 parts of xylyl-4 and 1-2 parts of N-phenyl-2- aniline. The polyurethane construction glue is good in strength, excellent in adhesive property, resistant to acid and alkali, resistant to high temperature and resistant to mould.
Description
Technical field
The present invention relates to the technical field of fire retardant matter, particularly relate to a kind of high-strength polyurethane building adhesive and preparation method thereof.
Background technology
Still at use masonry of cement mortar body of wall in current construction industry, still with sand-cement slurry sticking heat-preservation plate, marble, ceramic tile, but limit by winter temperature, construction quality is difficult to guarantee.
Chinese patent CN104845560A discloses a kind of Building Adhesive, and it is made up of the raw material of following weight part: oxalic acid 2-3 part, borax 0.5-1 part, urea 4-6 part, methylcellulose gum 3-7 part, talcum powder 3-6 part, supervinyi chloride resin 12-20 part, water 200-250 part.Although the comparatively environmental protection of its sizing agent, its intensity is poor.
Summary of the invention
In view of this, one aspect of the present invention provides a kind of high-strength polyurethane building adhesive.
A kind of high-strength polyurethane building adhesive, its raw material comprises 36 ~ 44 parts of isocyanic ester, 38 ~ 45 parts of chloroprene rubbers, 2 ~ 3 parts of zinc chloride, 2 ~ 3 parts of magnesium chlorides, 2 ~ 3 parts of xylyls-4,1 ~ 2 part of N-phenyl-2-aniline according to mass parts.
Aforementioned " isocyanic ester " refers to the compound containing-NCO base.As isocyanic ester of the present invention, to its kind without special restriction, can be aliphatics or aromatic isocyanic ester.Both can be such as unitary isocyanic ester, such as methyl isocyanate; Also can be binary isocyanic ester, as isophorone diisocyanate (IPDI), tolylene diisocyanate (TDI); Can also be triisocyanate, as triphenylmethane triisocyanate.Preferably, be triphenylmethane triisocyanate.
Comprise isocyanic ester in the present invention, which raises adhesive property, enhance acid and alkali-resistance, high temperature resistant, fungicidal properties.
Another aspect of the invention provides the preparation method of above-mentioned polyurethane building glue.
Prepare the method as above-mentioned polyurethane building glue, according to mass parts, each raw material is mixed.
The mode of above-mentioned mixing can adopt the mixing means of this area routine, such as, adopt conventional churned mechanically equipment to mix.The temperature of mixing is without particular requirement.Mixing time to ensure that being uniformly dispersed of raw material is as the criterion, by product by its stability of standing observation judge mixing homogeneity.
Polyurethane building glue of the present invention, adds isocyanic ester, and it not only increases the intensity of building adhesive, goes back adhesive property, enhances acid and alkali-resistance, high temperature resistant, fungicidal properties.
Embodiment
Technical scheme of the present invention is further illustrated below in conjunction with embodiment.
Embodiment 1
In this example, the raw material of building adhesive comprises 36 parts of isocyanic ester, 38 parts of chloroprene rubbers, 2 parts of zinc chloride, 2 ~ 3 parts of magnesium chlorides, 2 parts of xylyls-4,1 part of N-phenyl-2-aniline according to mass parts.
Embodiment 2
In this example, comprise 44 parts of isocyanic ester, 45 parts of chloroprene rubbers, 3 parts of zinc chloride, 3 parts of magnesium chlorides, 3 parts of xylyls-4,2 parts of N-phenyl-2-aniline.
Embodiment 3
In this example, comprise 40 parts of isocyanic ester, 40 parts of chloroprene rubbers, 2.5 parts of zinc chloride, 2.5 parts of magnesium chlorides, 2.5 parts of xylyls-4,1.5 parts of N-phenyl-2-aniline.
Building adhesive of the present invention has higher intensity, in addition its higher adhesive property, acid and alkali-resistance, high temperature resistant, fungicidal properties.In low temperature-40 DEG C, still have reliably good cohesive strength, high temperature resistant reach 120 DEG C non-fusible.
Applicant states, the present invention illustrates detailed process equipment and process flow process of the present invention by above-described embodiment, but the present invention is not limited to above-mentioned detailed process equipment and process flow process, namely do not mean that the present invention must rely on above-mentioned detailed process equipment and process flow process and could implement.Person of ordinary skill in the field should understand, any improvement in the present invention, to equivalence replacement and the interpolation of ancillary component, the concrete way choice etc. of each raw material of product of the present invention, all drops within protection scope of the present invention and open scope.
