Journey.The production assembly efficiency of vehicle factor can be significantly improved.
Detailed description of the invention
Fig. 1 is that existing two-component packs schematic diagram 1.
Fig. 2 is that existing two-component packs schematic diagram 2.
Specific embodiment
Technical key point of the present invention is further illustrated below by embodiment:
This patent is urged using the synergistic effect of the active resin compound system of differential responses, ethyl orthosilicate and catalyst
Changing to be formed, there is the cross-linking system of interpenetrating networks to improve initial bonding to effectively improve the curing performance of this product
Intensity, to realize the function of rapid link positioning；The simple production process of this patent product is easily accomplished scale production,
It can be widely applied and significantly improve the production assembly efficiency of vehicle factor.
Compounding principle of the invention is:
The end group of trimethoxy silane modified polyether has very high reactivity, in cooperateing with for crosslinking agent and catalyst
It under effect, can be reacted with the moisture in environment rapidly, and form preliminary cross-linked structure, so that assigning product initial stage must
The adhesive strength wanted；In comparison, the terminal reactive of dimethoxysilane modified polyether is lower, and reaction speed lags behind front three
Oxysilane modified polyether, with the continuity of time, dimethoxysilane modified polyether resin continues to participate in cross-linking reaction, thus
The structure of interpenetrating networks is formed, the final adhesive strength of product is further promoted, and it is highly beneficial to ensure that the product has
Mechanical property.At the same time, test of many times the result shows that, the compound proportion of two kinds of silane modified polyether resins is between 2~4:1
Between effect it is most prominent, when the accounting of trimethoxy silane modified polyether is higher, the crosslink density of obtained product is high, just
Beginning adhesive strength can satisfy quick-setting requirement, but product embrittlement simultaneously, and elongation rate of tensile failure is not able to satisfy wanting for standard
It asks；When the accounting of trimethoxy silane modified polyether is lower, the initial bond strength of acquired product is unable to satisfy quickly solid
The requirement of change.
Performance test

Table 10
With comparison of the existing two-component materials in construction:
And existing two-component construction packaging such as Fig. 1,2, two-component sealant is divided into A, B component, wherein general component A is
Host agent, B component are catalyst system.It is squeezed out by the equipment of Fig. 2, then carries out AB mixing by squeezing out sharp mouth, then be glued base
Material surface.Different from the curing mode of one pack system from outward appearance to inner essence, two-component solidifies simultaneously to be inside and outside, thus needs to guarantee sharp mouth
In time for mixing of A/B need very short, and the glue for mixing metacone face in the mouth must be also finished at once, otherwise be needed to frequently replace
Sharp mouth, compares common one pack system point mouth, and the cost of the Jiao Zui is higher.
Two-component is because of its complicated situ configuration technique, although actually it is advantageous on curing time, by
The time and cost for causing it finally to spend in complicated complex process are more.
