Abstract
The invention discloses colorless glass cement for a glass curtain wall. The colorless glass cement is characterized in that the viscosity of the adopted alpha,omega-dihydroxyl polydimethylsiloxane is 10,000-100,000cp, and different viscosities are reasonably matched at a weight ratio of (10,000-20,000cp):(20,000-50,000cp):(50,000-100,000cp)=1:(2-3):(4-6).
Description
Technical field
The present invention relates to high molecule sealing materials technical field, particularly a kind of flint glass glue for glass curtain wall.
Background technology
Glass curtain wall is a kind of construction wall trailing of novelty, is the notable feature in modern high-rise building epoch.Along with the development of science and technology and people are to the pursuit of U.S., glass curtain wall obtains applying more and more widely in the every field of building.Many architects adopt glass curtain wall, in order to expand the visual field, draw scape to enter the room, space is made to have more extensibility, interactive and fluency, buildings is made to have penetrating sense and associative perception, require minimum blocking, and this requirement can be realized without frame curtain wall (comprising full glass curtain wall and point supported curtain wall).
The overwhelming majority that current glass curtain wall uses is double glazing, particularly point supported curtain wall major part adopts transparent white glass and silver-gray aluminium alloy extrusions, for exigent owner, if adopt traditional black or dark seal gum to be difficult to reach the globality effect of curtain wall and visual attractive in appearance.White or transparent seal gum is being sought to meet this requirement by present many curtain wall enterprises.But because of the proper property of current filler, make it all have specific color, its color is mostly black or dark color, in addition, existing seal gum is due to composition and proportioning restriction, and its performance more and more can not be satisfied the demand.
Summary of the invention
For the deficiencies in the prior art, an object of the present invention is to provide a kind of flint glass glue for glass curtain wall, by the selection of moiety of composition glass cement and collocation, and the performance of glass cement is had great improvement.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of flint glass glue for glass curtain wall, this glass cement is made up of the following component with parts by weight: α, alpha, omega-dihydroxy polydimethyl siloxane 60-70 part, methyl-silicone oil 5-8 part, dimethyl two Diacetylmonoxime base silane 8-10 part, four Diacetylmonoxime base silane 8-10 parts, aminopropyl trimethoxysilane 3-5 part, γ-(methacryloxypropyl) propyl trimethoxy silicane 3-5 part, dibutyl tin dilaurate 0.2-0.4 part, aerosil 80-90 part, ESCALOL 567 2-4 part, 4-benzoyloxy-2, 2, 6, 6-tetramethyl piperidine 1-2 part, described α, its viscosity of alpha, omega-dihydroxy polydimethyl siloxane is 10000cp-100000cp, and between different viscosity, need rational Match to use, its part by weight is 10000cp-20000cp: 20000cp-50000cp: 50000cp-100000cp=1: (2-3): (4-6).
This glass cement can be prepared as follows:
In kneader, α is added successively at high temperature 170 DEG C-180 DEG C, alpha, omega-dihydroxy polydimethyl siloxane, methyl-silicone oil, dimethyl two Diacetylmonoxime base silane, four Diacetylmonoxime base silanes, dibutyl tin dilaurate, ESCALOL 567, 4-benzoyloxy-2, 2, 6, 6-tetramethyl piperidine, blended 20-25 minute under vacuum protection, add aerosil filler again, 30-40 minute is mixed under vacuum protection, then aminopropyl trimethoxysilane is added, γ-(methacryloxypropyl) propyl trimethoxy silicane vacuum mixing is after 35-45 minute.
The present invention has following beneficial effect:
1) the present invention is on the basis of great many of experiments, determine the α by adopting different viscosity, the technical scheme that alpha, omega-dihydroxy polydimethyl siloxane uses according to different ratios coupling, and find that the intensity of the glass cement prepared according to aforementioned proportion and hardness ratio prior art improve greatly.When other components are constant, only with α, it is different that alpha, omega-dihydroxy polydimethyl siloxane does not carry out viscosity, glass cement prepared by not to scale proportioning is compared, every mechanical performance index improves 15-20% than prior art, achieves unexpected technique effect, coordinates and carries out assembly experiment to multiple may the selection of softening agent, linking agent, coupling agent, determine above-mentioned composition component and proportioning, make over-all properties improve more than 30% than prior art.Test by GB/T 528-2009, its tensile strength can reach 4.6-5.4MPa, and elongation is 340-420%, hardness (shore A) 45-55.The glass cement of preparation have extrudabilityly be less than 3 minutes, surface drying is less than 40 minutes, and the excellent properties such as good tensile bond.
2) glass cement clear, colorless of the present invention, is suitable for large glass curtain wall and uses.
