Example Embodiment

[0007] To make the particleboard of the present invention, take 50 kilograms of sawn or crushed crop straw, 5 kilograms of carboxymethyl cellulose, 1 kilogram of alum, 2 kilograms of gypsum powder, 3 kilograms of moisture-proofing agent, anhydrous calcium chloride or other moisture-proofing agents for wood, and 10 kg of water. First, mix the moisture-proof agent and water to make a spray and put it into the sprayer. Stir the rest of the raw materials evenly with a mixer. While stirring, use the spray for humidification. Put the mixed raw materials into the mold for manual compression molding, the pressure is 80 -160kg / m 2 , And then dried in a drying furnace, drying temperature 60-100 ℃, time 16-24 hours, out of the furnace for edging treatment is the finished product.

Abstract

The present invention discloses a particleboard and a production method. The particleboard consists of 65 to 75 weight percent of sawdust or crop straw, 5 to 8 weight percent of carboxymethyl cellulose, 1 to 2 weight percent of white alum, 2 to 4 weight percent of gypsum powder, 4 to 6 weight percent of moisture-resistant agent and 10 to 20 weight percent of water. The particleboard takes carboxymethyl cellulose as adhesive, together with moisture-resistant agent and is drying manufactured after being compressed by manpower or machine. The particleboard of the present invention is nontoxic, odorless, benzene-free, amine-free, formaldehyde-free and radiation-free. The particleboard is a novel environmental protection particleboard and is used for manufacturing various kinds of furniture, doors, windows, and wall sheet and plank stuff. The present invention can be realized by handwork and does not need large-scale heat pressing machine.

Description

technical field [0001] The invention relates to a chipboard and a manufacturing method thereof. Background technique [0002] Now furniture, doors and windows, wall panels, and boards are mostly made of plywood, fiberboard, calcium-plastic board, gypsum board, and particle board. The above-mentioned decoration materials are expensive and have unsatisfactory moisture-proof performance. Ammonia and other toxic gases are released, and the environmental protection performance is poor. Contents of the invention [0003] The object of the present invention is to provide a particle board with excellent moisture-proof and environmental protection performance, and the production method of the particle board is simple. [0004] The technical scheme of the present invention is: the particle board of the present invention is made of sawn or crop straw, 5-8% carboxymethyl cellulose, 1-2% alum, 2-4% gypsum powder in weight ratio , 4-6% moisture-proof agent and 10-20% water. [0005] ...
