Want one of developing direction and the main path of construction industry transition and upgrade.Assembled architecture is by pre-constructed unit in assemble in site
Made of build, large number of deep wide seam, these depths can be generated after assembled architecture outer wall hanging plate or Exterior Wall Components splicing
The formation of wide seam not only expands the application field of sealing material, while proposing more to the deep cure rate of sealing material
High requirement.Sealing material is divided into one-component sealing material and bi-component sealing material according to product packaging.One-component product makes
With convenient, but solidify the moisture relied primarily in air, is affected by the external environment significant, solidifies from outward appearance to inner essence, deep cure is slow,
And curing depth is limited, is not suitable for the waterproof sealing of deep wide seam.It is aqueous using itself institute when bi-component sealing material solidifies
Point, glue-line outwardly and inwardly solidifies simultaneously, and solidification rate is fast, can be widely applied to the neck such as building, automobile, locomotive, electronic apparatus
Domain.
Silicone, polyurethane, silane modified polyether glue and polysulfide sealant are global four big most important sealant materials.State
Interior silicone adhesive and polysulfide sealant mechanical property and in terms of it is suitable with same kind of products at abroad, but weatherability is poor,
Xanthochromia, dusting, cracking phenomena easily has occurred in service phase in colloid, pollutes bonding substrates, does great damage to building beauty.
Polyurethane sealant has good mechanical property, is widely used in multiple fields, but the weather resistance of product is poor.Silane
The main chain of modified polyether molecule is the macromolecular polyethers of methoxy silane sealing end, is formed after solidification using-Si-O-Si- as skeleton
Three-dimensional space network structure has the good weather resistance of silicone sealant and anti-deformational displacement ability, and has polyurethane
The good caking property of sealant, paintability and low pollution.The silane of silane modified polyether seal glue especially bi-component changes
Property polyether seal glue in Japanese architecture sealant market occupy leading position, also occupy the market part of significant proportion in states such as America and Europes
Volume.In China, the research and development and application of silane modified polyether seal glue are started late, and are still in the marketing stage at present.
As 105219337 A of Chinese patent CN discloses a kind of dual-component silicane modified polyether sealing material and its preparation
Method.Used light stabilizer is UV-P, UV-9,326,327,328,531,540,622,744,770,788 of BASF
One of or more than one mixture.The above light stabilizer is the stabilizer of more common low molecular weight, inevitably
There are volatile, easy to migrate and the disadvantages of intolerant to extraction, especially liquid stabilisers of low molecular weight diffuse to bonding after precipitation
Substrate is even penetrated into interface.
In conclusion a kind of good weatherability how is researched and developed, the fast dual-component silicane modified polyether sealing of deep cure rate
Glue is fluid sealant for construction field technical staff's urgent problem to be solved.
The disclosure of background above technology contents is only used for auxiliary and understands inventive concept and technical solution of the invention, not
The prior art for necessarily belonging to present patent application shows above content in the applying date of present patent application in no tangible proof
In the case where having disclosed, above-mentioned background technique should not be taken to the novelty and creativeness of evaluation the application.
