Alternative adhesive powder for industrial flour and preparation method

Abstract

The invention discloses an adhesive powder capable of replacing the traditional industrial wheat flour, which is featured with grain saving, low cost and highly water resistance and is used for effectively catching formaldehyde and reducing formaldehyde content, and a preparation method. According to the invention, a formula of the adhesive powder comprises the following materials in percentage by weight: a material A: a soil material using 20-50% of sodium based soil; a material B: a powder material using 30-60% of cypress powder; a material C: an adhesive using 10-20% of solid oxidized starch adhesive; a material D: a water resistant agent using 10-15% of shale; a material E: a moisturizing dispersant using 0.8-2% of sodium lauryl sulfate; a material F: a formaldehyde catching agent using 2-4% of sodium percarbonate; a material G: a curing agent using 0.3-1.2% of aluminum sulfate and a material H: a coupling agent using 1-3% of K-602.

Description

technical field [0001] The invention relates to the field of rubber fillers for plate processing, in particular to a glue powder for replacing industrial flour and a preparation process thereof. Background technique [0002] Humans have a long history of using wood adhesives. In the 17th and 18th centuries, European and American countries had established adhesive factories. At the beginning of the 19th century, commercial casein was available in Europe, and the commercial production of adhesives gradually developed. At the end of the 19th century and the beginning of the 20th century, synthetic resins entered the field of adhesives. In the 1930s, the wood industry began to use phenolic and urea-formaldehyde resin glues. In order to prolong the shelf life, this kind of glue is generally made thinner when it leaves the factory. Therefore, wood-based panel companies add industrial wheat flour to the glue before production. , to absorb water, thicken and increase instant visco...

AI Technical Summary

Problems solved by technology

[0003] In addition, traditional flour only has the functions of absorbing water, thickening, and instantly increasing viscosity in the glue mixing process. It has a single effect and cannot capture formaldehyde in wood-based panels, let alone increase water resistance and toughness.
