Embodiment 1

[0021] In this example, rice straw is selected as the raw material of the plywood, and the rice straw is required to be dry rice straw, and then the rice straw is crushed into a 50-mesh powder with a pulverizer, and then 50 kg of the 50-mesh rice straw powder is taken out and put into a container , adding 15 kg of light magnesium oxide to the rice straw powder, the light magnesium oxide is a white amorphous powder with a melting point of about 2852° C., odorless, tasteless and non-toxic. Insoluble in water and organic solvents, soluble in acid or ammonium salt solution, molecular formula: MgO 2 . Fully stir and mix the rice straw powder and light magnesium oxide powder evenly, then add 35 kg of epoxy adhesive to the mixture and continue stirring, after stirring evenly, mix the rice straw powder, light magnesium oxide and The epoxy-adhesive mixture is pushed into a prefabricated mold to form the finished plywood. The described prefabricated mold and pushing technology are the...

Embodiment 2

[0027] In this example, wheat straw is selected as the raw material of the plywood, and the wheat straw is required to be dry rice straw, and then the wheat straw is crushed into a 70-mesh powder with a pulverizer, and then 40 kg of 50-mesh wheat straw powder is taken out and put into a container , adding 20 kilograms of light magnesium oxide to the wheat straw powder. Fully stir and mix the wheat straw powder and light magnesium oxide powder, then add 40 kg of epoxy adhesive to the mixture and continue to stir, after stirring evenly, mix the wheat straw powder, light magnesium oxide and The epoxy-adhesive mixture is pushed into a prefabricated mold to form the finished plywood.

Embodiment 3

[0029] In this embodiment, the mixed powder of wheat straw and rice straw is selected as the raw material of the present invention. The wheat straw and rice straw are required to be dry, and then the wheat straw and rice straw are pulverized into 100-mesh powder with a pulverizer respectively. Take 22.5 kg each of 100-mesh wheat straw powder and rice straw powder, put them into a container and stir evenly, add 10 kg of light magnesium oxide to the mixed powder of the wheat straw powder and rice straw powder. Stir and mix the mixed powder of wheat straw powder and rice straw powder and light magnesium oxide powder evenly, then add 35 kg of epoxy adhesive to the mixture and continue stirring. The mixture of powder and rice straw powder, light magnesia and epoxy adhesive is put into a prefabricated mold for pushing and processing to become a finished plywood product.

Abstract

Disclosed are a composites plate of rice and wheat straw and the process thereof, which belong to the technical field of processing of constructional or decorative planks. The invention is characterized in that the composites plate is processed by the materials according to weight percentage of rice straw powder, wheat straw powder or mixed powder of rice and wheat powder 40-60%, light magnesium-oxide 10-30% and epoxy adhesive 30-40%. The process comprises the steps that preparing rice straw powder, wheat straw powder or mixed powder of rice and wheat powder according to the weight percentage and placing the powder in a container, then adding the light magnesium-oxide in the rice straw powder, wheat straw powder or mixed powder of rice and wheat powder according to the weight percentage, then mixing the mixture homogeneously under constant temperature, then adding the epoxy adhesive according to the weight percentage, stirring the mixture continuously homogeneously under constant temperature, pouring the stirred mixture in a prefabricated mould, and finally required plate finished products are accomplished after pushing process. The invention has easily accessible materials, solves the problem of further processing, which is high in strength, firm and durable.

Description

Technical field: [0001] The invention relates to a rice-wheat straw plywood and its processing technology, which belongs to the technical field of plate processing for building or decoration. In particular, a technology that can replace wood plywood or compressed board, using rice straw and straw to make plywood. Background technique: [0002] Existing plywood is usually pressed with sawdust or bonded with wood. For example, in Chinese Patent No. 01142809.0, "A kind of high-quality solid wood three-layer plywood processing wood floor and construction method" is described. A panel with a sawing mold is provided on the sawing surface of an electric disc saw or an electric blade cutting saw, and two sets of parallel grooves are arranged on the width direction of the panel, arranged on both sides of the front center line of the saw kerf. The two groups of parallel grooves are provided with a slidable limit frame, and a single-head bolt is arranged in the limit frame, and the b...
