Abstract

The invention discloses a preparation method of a binding agent applied to an environment-friendly aluminum structure composite material and belongs to the field of binding agent preparation.The method comprises the following steps: esterifying dimethyl terephthalate, ethylene glycol, hexanedioic acid, 1,4 butanediol under certain conditions, then carrying out condensation polymerization on the raw materials to obtain polyester polyol; mixing the obtained polyester polyol with polyether glycol, then formulating the mixture by inorganic filler, tackified resin and organosilicon coupling agent according to proportion, thus obtaining an environment-friendly aluminum structure composite material compound binding agent.In the preparation method, through the design of the structure of polyesterchain segment, introduction of polyether glycol chain segment unit and adjustment of proportioning of different inorganic fillers, the prepared binding agent is endowed with extremely high aluminum base material strength and fine operability; in addition, with the binding agent adopted, various compound materials containing aluminum base materials can be produced.The aluminum honeycomb compound product made from the binding agent of the invention features high mechanical property, no discharge of toxic and irritant gas and excellent weather resistance.

Description

technical field [0001] The invention relates to the field of preparation of adhesives, in particular to a method for preparing adhesives for environment-friendly aluminum structure composite materials. Background technique [0002] Currently, aluminum-containing substrates are bonded together by aluminum structural adhesives, making it a new class of composite materials with unique properties and low cost. A typical product of this composite material is an aluminum honeycomb panel, which has the advantages of light weight and less than 1 / 3 of the weight of an aluminum veneer. Because the aluminum honeycomb panel has the advantages of good toughness and high strength, it can be designed for heavy panels, cheap to maintain, and has good sound insulation and heat insulation performance. This aluminum honeycomb composite material is mainly used in the construction and decoration industries, and has excellent properties such as high wind pressure resistance, shock absorption, so...
