Abstract
The invention discloses a preparation method of an unsaturated dibasic organic acid adhesive, which comprises the following steps: s1: adding 400g of water into the reaction kettle, starting stirring, controlling the stirring speed to uniformly disperse the materials, wherein the stirring speed is 200 r/min; s2: adding 20g of unsaturated dibasic organic acid with the pH value of 2 into a reaction kettle for dissolving; s3: slowly adding 100g of amylopectin with the pH value of 3, uniformly stirring, suspending feeding if the agglomeration phenomenon caused by non-uniform dispersion occurs, continuing feeding after the agglomeration becomes smaller, and increasing the stirring speed if a large amount of foam is generated on the liquid surface so as to avoid starch dust caused by excessively high feeding speed; s4: slowly adding 2g of organic base catalyst with the pH value of 3, and uniformly stirring for 1 h; s5: and (6) discharging. The unsaturated binary organic acid adhesive prepared by the process is used for paper food packaging, is healthy and safe, is used for decoration of families, hotels and the like, is colorless, odorless and pollution-free, has high mechanical property when being used for manufacturing high-grade hardwood furniture, and provides firm and durable binding property.
Description
Technical Field
The invention belongs to the technical field of biomass glue making, and particularly relates to a preparation method of an unsaturated dibasic organic acid adhesive.
Background
The unsaturated binary organic acid adhesive (biological glue) disclosed by the invention is expected to completely distinguish volatile pollution of the adhesive by people.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a preparation method of an unsaturated dibasic organic acid adhesive.
The technical scheme of the invention is summarized as follows:
