The invention discloses a kind of double-layer plate and strengthen glue, upper strata steel plate strengthen glue and lower floor's steel plate strengthens glue and forms, be specifically designed on the fragile position spreading upon motor-car body sheet, play sound insulation damping, the effect of enhancing armor plate strength.Technical scheme disclosed in the present application from steel plate adhesive property, by the contractility etc. after improving product and solidifying in terms of set about, reach beneficially steel plate and smear, sound insulation damping, effectively strengthen the effect of armor plate strength.
Description
Technical field
Automotive material technical field of the present invention, is specifically related to a kind of double-layer plate and strengthens glue, be specifically designed to and spread upon automobile
On the fragile position of vehicle body steel plate (such as car door, hood etc.), play sound insulation damping, the effect of enhancing armor plate strength.
Background technology
Numerous automobile production producers strengthen armor plate strength by pasting one layer of adhesive tape material at steel plate fragility position, this
Way also exists that adhesive tape easily comes off, adhesive tape is not suitable for the defects such as steel plate curved surface or crooked position.
It addition, although some automobile factory is to strengthen glue by spraying one layer of steel plate at surface of steel plate, reach steel plate strengthen and
The effect of damping, but during to winter, temperature is relatively low, and after oven for solidifying, if product strength is the highest, product flatulence of heat type is cold
Contracting, it is easy to make steel plate draw recessed, modification.
Further, strengthen glue by spraying double-layer plate to reach steel plate enhancing and the effect of damping.Spraying two-layer glue, lower floor
Main component is rubber, though in the winter time time, after high-temperature baking, better softness when rubber-based products is expanded with heat and contract with cold, no
Easily make steel plate draw recessed, deformation occurs.Upper strata is epoxy resin, reaches steel plate and strengthens and the effect of damping.This technique is at automobile
During factory's spraying, needing to spray two kinds of products, working hour lengthens；Maintenance of equipment increases with upkeep cost.
Summary of the invention
The technical problem to be solved is: provides a kind of intensity that can improve upper strata product, preferably reaches
The double-layer plate of the effect that steel plate strengthens strengthens glue.
For solving above-mentioned technical problem, the technical scheme that the present invention provides is: a kind of double-layer plate strengthens glue, by upper strata steel
Plate strengthens glue and lower floor's steel plate strengthens glue (near one layer of steel plate) and forms:
Upper strata steel plate strengthens glue, based on weight/mass percentage composition, consisting of: bisphenol A type epoxy resin 20～26%, butyronitrile
