Abstract

A kind of crack resistance type exterior wall powder of lacquer putty for use on is provided, not only cracking resistance is good for the powder of lacquer putty for use on, and workability is all compared like product with drying property and is improved a lot.The powder of lacquer putty for use on includes portland cement, dicalcium powder, can disperse rubber powder, polyvinyl alcohol rubber powder, hydroxypropyl methyl cellulose ether, water reducer, wood fibre, retarder, anti-sagging agent, disodium ethylene diamine tetraacetate.

Description

A kind of crack resistance type exterior wall powder of lacquer putty for use on
Technical field
The present invention relates to a kind of feature building coating material, and in particular to outside a kind of building with good cracking resistance Wall putty.
Background technology
The cement plaster for using in the prior art, it is easy to ftracture, influences the attractive in appearance of metope, and tension is strong in itself with cement for this Degree poor performance has certain relation, also has certain relation with engineering time and process.Tradition improves exterior wall putty splitting resistance Method be mainly enhancing component and elastic component be mixed into composition, such as CN1532232A discloses a kind of skin Putty, wherein adding hydroxypropyl methyl fiber, polypropene staple song redispersable latex powder.CN1448445A discloses one Color elastic high-strength waterproof putty powder is planted, wherein also adding substantial amounts of fiber substance and elastic latex.
In addition, exterior wall putty outer surface generally can also cover with paint, lacquer, colour wash, etc. decorative layer, such as exterior coating, therefore, exterior wall putty is also needed There are quick-drying and the good amalgamation with decoration of exterior wall layer.And as it was previously stated, crack resistance in order to improve putty, Ke Yizeng Plus elastic component, but elastic component can excessively influence the intensity and quick-drying of putty, it is also possible to increase reinforcing material component example Such as fiber, but, the application property for using the exterior wall putty that cement can be caused to be main component of excessive enhancing component is deteriorated.
The content of the invention
The present invention is based on drawbacks described above present in prior art, there is provided a kind of crack resistance type exterior wall powder of lacquer putty for use on, the putty Not only cracking resistance is good for powder, and workability is all compared like product with drying property and improved a lot.
A kind of crack resistance type exterior wall powder of lacquer putty for use on, it includes portland cement, dicalcium powder, can disperse rubber powder, polyvinyl alcohol Rubber powder, hydroxypropyl methyl cellulose ether, water reducer, wood fibre, retarder, anti-sagging agent, disodium ethylene diamine tetraacetate.
It is preferred that, the crack resistance type exterior wall powder of lacquer putty for use on includes portland cement 300-500, dicalcium powder 500- by weight 600th, re-dispersible glue powder 15-25, polyvinyl alcohol rubber powder 5-10, hydroxypropyl methyl cellulose ether 3-4, water reducer 2-3, wooden fibre Dimension 2-4, retarder 0.2-0.4, anti-sagging agent 0.3-0.6, disodium ethylene diamine tetraacetate 0.5-1.0.
It is preferred that, the retarder is sodium gluconate, and the anti-sagging agent is farina, the re-dispersible glue powder It is vinyl acetate-ethylene copolymer emulsion.
It is also preferred that water reducer is made up of the sodiumβ-naphthalenesulfonate of 60-90% and the beta naphthal -7- sulfonic acid of 10-40%.
Also most preferably, the cement is PO52.5 Taihang cement, and the re-dispersible glue powder is that the triumphant board of prestige is redispersible Latex powder.
Present applicant it has surprisingly been found that, in the preparation process of cement mo(u)ld putty powder for exterior wall, add β-naphthalene Sodium sulfonate and beta naphthal -7- sulfonic acid can accelerate the curing rate of putty, meanwhile, in rubber powder and wood fibre content identical feelings Under condition, the cracking resistance of putty is further enhanced.
In addition, present applicant is also it has furthermore been found that in portland cement, polyvinyl alcohol rubber powder, vinyl acetate-second Alkene copolymer emulsion is to add disodium ethylene diamine tetraacetate, the compression strength and bullet of powder of lacquer putty for use in the main powder of lacquer putty for use on being molded into point Property performance has unexpected raising.
Specific embodiment
Embodiment 1
The composition of the powder of lacquer putty for use on is as follows:
Its preparation technology is with construction technology:In agitator, add dicalcium powder, the triumphant board redispersable latex powder of prestige 5044N types, the type rubber powder of polyvinyl alcohol 801, hydroxypropyl methyl cellulose ether PMC-40US, wood fibre ZZC 500, gluconic acid Sodium BS types, farina AVB, disodium ethylene diamine tetraacetate.It is eventually adding PO52.5 Taihangs cement, sodiumβ-naphthalenesulfonate and 2- naphthalenes Phenol -7- sulfonic acid, then stirs.When using, in water: the ratio of ash=20: 100 adds water stirring, after stirring, is scraped Smear, and press polish, after after natural curing 5-7 days, you can carry out exterior coating primary coat.
Embodiment 2
Other conditions are same as Example 1, the difference is that only and are added without beta naphthal -7- sulfonic acid.
Embodiment 3
Other conditions are same as Example 1, to the difference is that only and replace " 2.5Kg beta-naphthalenesulfonic-acids with 3Kg sodiumβ-naphthalenesulfonates Sodium and 0.5Kg beta naphthal -7- sulfonic acid ".
Embodiment 4
Other conditions are same as Example 1, the difference is that only that with vinyl acetate/versatic acid ethylene copolymer be main The rubber powder of composition can be in dispersion rubber powder instead of the triumphant board redispersable latex powder 5044N types of prestige.
Comparative example 1
Other conditions are same as Example 1, and difference is to be added without 2.5Kg sodiumβ-naphthalenesulfonates and 0.5Kg 2- naphthalenes Phenol -7- sulfonic acid.
Comparative example 2
Other conditions are same as Example 1, and difference is to be added without disodium ethylene diamine tetraacetate.
Comparative example 3
Other conditions are identical with comparative example 1, and difference is that the content of wood fibre is 10Kg.
The performance parameter list of the embodiment of table 1 and comparative example
