Abstract

The invention discloses a filler special for glue mixing of a plywood, comprising the following components: a clay mineral, sawdust, a silane coupling agent, an organic acid, alcohol and a viscosity regulator; a preparation process of the filler comprises the steps of: firstly, respectively grinding the clay mineral and the sawdust into powder and proportionally mixing the clay mineral and the sawdust in a mixer to form mixed powder; secondly, proportionally placing the silane coupling agent, the organic acid and the alcohol in a container and stirring by a stirrer to form mixed liquor; thirdly, slowly pouring the mixed liquor prepared in the last step into the mixed powder, starting the mixer at the same time and then warming to carry out full reaction between the mixed liquor and the mixed powder; and fourthly, adding the viscosity regulator in the reacted mixed powder and stirring well. The filler for glue mixing of plywood has the characteristics of low cost, strong viscosity and good economic benefit.

Description

technical field [0001] The invention relates to a filler and a preparation process thereof, in particular to a special filler for plywood glue adjustment and a preparation process thereof. Background technique [0002] Urea-formaldehyde resin, melamine resin and phenolic resin (adhesive) are the main types of glue used in the production of plywood, and their cost accounts for a large proportion of the cost of plywood, and reducing the cost of adhesive is one of the important ways to improve the economic benefits of plywood factories. In the production of plywood, fillers are good modifiers for adhesives. Adding appropriate fillers to adhesives can not only reduce the amount of glue used, reduce production costs, but also improve the performance of the adhesive. At present, wheat flour and soybean flour are mainly used as adhesive fillers, both of which are food crops, which not only waste food, but also have high prices, which affect the economic benefits of enterprises. ...
