Problems solved by technology

[0006] Although the Chinese invention patents of ZL200810163948.3 and ZL200810162399.8 provide a better bonding method, there are still some problems in actual operation, for example, air bubbles are easily generated during the baking process in the oven, thereby reducing the bonding strength ; Dimethylamine ethanol is relatively expensive, etc.

Abstract

The invention discloses a preparation of a water-based adhesive and a preparation method of a metal / polypropylene composite material. The preparation of the water-based adhesive is characterized in that the preparation steps are as follows: a, grafting and copolymerizing chlorinated polypropylene; and b, preparing the adhesive, wherein the adhesive is uniformly coated on the upper part of a metal sample strip; a polypropylene sheet is adhered on the metal sample strip by the adhesive; the metal and the polypropylene sheet are clamped on an injection molding machine, and placed in an oven with the temperature of 100 DEG C-150 DEG C for 15-60 minutes after the clamping. Compared with the prior art, the preparation of the water-based adhesive and the reparation method of metal / polypropylene composite material have the advantages that the adhesive is better in bonding strength and good in environment friendliness; and the composite material is simple to prepare and capable of being produced in mass.

Description

technical field [0001] The invention relates to the preparation of an adhesive and a method for making a composite material, in particular to a method for preparing a water-based adhesive and a method for making a metal / polypropylene composite material. Background technique [0002] With the continuous improvement of the level of science and technology, people have higher and higher requirements for composite materials, not only requiring excellent comprehensive performance, but more importantly, environmental protection. In the early composite materials, polyvinyl chloride (referred to as PVC) was composited with metal, and it has been widely used in interior and exterior decoration of automobiles, architectural appearance, interior decoration, aerospace and military. However, with the European Union's ban on the import of PVC materials, the SUS / PP composite material formed by bonding a layer of SUS on the surface with PP as the main body has both low price, light weight, e...
