Description
Technical field
The invention belongs to adhesive for polyurethane and preparation method thereof technical field and in particular to a kind of solvent-free do not foam poly-
Urethane structural adhesive and preparation method thereof.
Background technology
Substantial amounts of polar group is contained, such as in adhesive for polyurethane molecule：The very high isocyanate groups of activity（-
NCO）And carbamate groups（-NHCOO-）, so it can have good adhesive property with most of materials, therefore its
Market application is quite extensive：The usage amount of the similar adhesive of China annual all increasing, but all based on solvent-borne type, with society
Development, the environmental consciousness of the mankind steps up, environmentally friendly solvent-free, progressively substitute solvent type adhesive, no-solvent type
Adhesive is because having the advantages that environmental protection, nontoxic, economy, smell are little, curing process is simple, save energy becomes the focus of research.
At present, it is short to there is the operating time in common on market solvent-free double-component polyurethane structural adhesive, solidification process
In be easily subject to moisture to be affected a large amount of bubbles of generation and then affect adhesive strength and the shortcoming of later stage reliability.Ask for solving this
Topic, needs one kind to be affected by moisture little, and in solidification process, bubble-free produces and operating time adjustable adhesive, to adapt to visitor
The demand at family.
Content of the invention
It is an object of the invention to solving existing two component polyurethane structural adhesive, to there is pollution environment, operating time short
Adjustable extent is narrow and solidification process in be easy to the problem that foams, there is provided a kind of solvent-free two component polyurethane knot that do not foam
Structure adhesive and preparation method thereof.
For solving above-mentioned technical problem, the technical solution used in the present invention is：A kind of solvent-free bi-component polyurethane that do not foam
Ester structure adhesive, it includes two kinds of components of A, B, and the mass ratio of affiliated two kinds of components of A, B is 4:1；

Reaction, simple to operate, i.e. curable at normal temperatures and there is excellent adhesive property, shear strength>15MPa, peel strength>
7N/mm；After A, B two component is uniformly mixed, under the conditions of 25 DEG C, gel time 30 ~ 80min is adjustable for mixture, and hardening time can
It is adjusted by the species of polyalcohol and poly methylene poly phenyl poly isocyanate, solve the double group of conventional no-solvent type
The segregation urethane structural adhesive operating time is short, the not high problem of adjustable degree；
2）Compared with traditional solvent-type double-component adhesive for polyurethane, the bi-component adhesive non-volatility of the present invention poisonous
Organic solvent, it is to avoid in Process of Applying Glue, organic solvent damages to the healthy of applying glue personnel, avoids organic simultaneously
In the middle of the air of solvent volatilization, pollution environment, is a kind of gluing agent material of clean environment firendly low energy consumption；
3）Traditional two component polyurethane structural adhesive is easily subject to the shadow of system and moisture in air in applying glue solidification process
Ring, make it that foamed phenomenon occurs further, and then reduce the impact of its adhesive property and use；And the two component polyurethane knot of the present invention
Structure gluing agent material is affected little by moisture and is hardly affected by ambient humidity, avoids foaming existing in applying glue solidification process
The generation of elephant, substantially increases the unfailing performance in later stage；
4）Compared with single-component polyurethane adhesive, it is adjustable that the dual-component polyurethane adhesive of the present invention has a curing rate, Gu
After change, glue-line is still, the features such as adhesive strength is high, and can adjust its thixotropic index by the amount of gas-phase silicon, to meet the work of client
Skill demand.
