Problems solved by technology

Because the papermaking method is treated with rice straw, it will seriously pollute water sources and rivers; and the solid waste of agricultural products such as rice bran, cotton stalks, bean stalks, and wheat stalks will be incinerated to produce serious pollution and affect air quality.
Such treatment methods often cause serious waste of resources and environmental pollution by solid waste, deeply affecting the current and future living environment, quality standards and health of human beings, and also violate the current world-renowned environmental protection requirements

example 1-3

[0025] Example 1-3 is to prepare catalytic coagulant, and its composition and consumption are shown in Table 1.

[0026] Preparation method: Mix the raw materials and stir evenly.

example 4-6

[0028] Example 4-6 is to prepare the material for the slate outer packing box.

[0029] The raw materials used are listed in Table 2.

[0030] Specific preparation process: send rice bran or straw (broken), catalytic coagulant and water into a mixer to mix and mix evenly, pour into a plate forming machine, vibrate and form, put it into a room with a temperature of 90°C for heating and curing for 17 hours, and then send it to an outdoor open-air pile Carry out 26 days of natural conservation in the field to get the required slatted product.

[0031] The wood substitute box made of this slat product has been tested on-site by a special person sent by the British Weiyuan Group, and the quality can meet the company's quality requirements such as compression resistance, flexural resistance, fire resistance, waterproof, insect resistance, sterility and load-bearing capacity. .

Abstract

The present invention relates to a imitation wood material made up by using agricultural wastes, and is characterized by that the agricultural wastes, catalytic coagulant composed of magnesium oxide,magnesium chloride aqueous solution, ferrous sulfate, phosphorus acid, urea-formaldehyde resin and water and water are stirred uniformly in stirring machine, extruded and formed, and cured so as to obtain the invented required imitation wood material with good chemical and mechanical properties. Said invented imitation wood material can be used as substitute of most of wood products.

Description

technical field [0001] The invention belongs to solid waste utilization technology, more precisely, it is a technology for converting agricultural waste, including rice bran, straw, cotton stalks, wheat stalks, etc., into wood-like materials. Background technique [0002] With China's entry into the WTO, following the reform and development of agricultural production, agricultural industrialization and standardization, how to improve the treatment and utilization of agricultural waste has become a subject that cannot be ignored. At present, the types of waste produced by agricultural production are very wide, such as rice bran, straw, cotton stalk, bean stalk, wheat stalk, etc. as everyone knows. In the past, these wastes were incinerated, and straw was used to make paper. Because the papermaking method is treated with straw, it will seriously pollute water sources and rivers; while the solid waste of agricultural products such as rice bran, cotton stalks, bean stalks, and ...
