Embodiment 2

[0009] Embodiment 2: when making size is 210mm * 210mm * 18mm board material, need to use carboxymethyl starch 88g, tap water 1000g by weight ratio, be heated to 50-90 ℃ and carboxymethyl potato starch is all dissolved, after adding 380g corrugated paper dust powder Stir well, put it into a mold after stirring evenly, and make a plate after forming, polishing, demoulding and drying.

Embodiment 3

[0010] Example 3: When making a plate with a size of 210mm × 210mm × 18mm, it is necessary to use 80g of carboxymethyl starch and 940g of tap water according to the weight ratio, and heat to 50-90°C to completely dissolve the carboxymethyl potato starch. After adding 400g of wheat straw powder Stir well, put it into a mold after stirring evenly, and make a plate after forming, polishing, demoulding and drying.

Abstract

The invention discloses a method for preparing boards from carboxymethyl starch serving as a binding agent and waste plant fibers. In the invention, the boards are prepared by the steps of uniformly mixing the carboxymethyl starch serving as the binding agent and the waste plant fiber powder, filling the mixed materials into a mold, molding, polishing the molded products, removing the mold and drying the obtained products. The boards prepared by the invention contain no substances, which are harmful for human body, such as formaldehyde, have the characteristics of light weight, low cost, simple manufacturing process, waste recycling and environmental protection and can be widely applied in the fields of construction, decoration, packaging and the like.

Description

technical field [0001] The invention relates to a method for making a novel board, in particular to a method for making a board by using carboxymethyl starch and waste plant fiber as raw materials. The board prepared by the method is suitable for the fields of packaging, home decoration, furniture manufacturing and the like. technical background [0002] At present, there are many kinds of construction, decoration and packaging boards used in the market, but most of them are made of natural resources, especially the boards made of wood, which not only wastes resources, but also And the cost is high. So we explored the method of making artificial panels from waste plant fibers. Aiming at the current situation that waste plant fibers are not reasonably and fully utilized, the present invention studies a simple and easy-to-operate method to make waste plant fibers into boards with a wide range of uses, which not only helps reduce the consumption of wood resources, but also can...
