Problems solved by technology

In addition, the deforestation due to the demand for wood and the burning of straw will cause a series of environmental and social problems
In recent years, some fiber boards produced by crop stalks and forestry residues have appeared on the market, such as the Chinese patent (patent application number 200710144690.8) "A Method for Manufacturing Plant Fiber Composite Wall Boards", which solves the problem of existing buildings. The wall material has the disadvantages of consuming a large amount of raw materials, high production cost, and uneven distribution of raw ...

Embodiment 1

[0040] Firstly, the crop stalks and forestry residues are respectively processed into 20-40 mesh fine fibers through the complete set of wood fiber production line, and become the primary materials of straw fine fibers and forestry residues fine fibers, which are set aside;

[0041] Next, put the standby straw fine fiber primary material and forestry residue fine fiber primary material into 10% bleaching powder aqueous solution respectively, soak for 12-24 hours, filter and dry, and obtain straw fine fiber and forestry residue after bleaching fine fibers, separately;

[0042] Third, take 1 part of flame retardant, 1 part of water repellent, 2 parts of adhesive, 45 parts of straw fine fibers and 45 parts of forestry residue fine fibers by weight, mix and stir evenly to obtain a mixture, and set aside;

[0043] Fourth, dry the spare mixture (moisture ≤ 2%), put it into the mold at a pressure of 500-2000T / m 2 , kept at a temperature of 50-80°C for 20 minutes and pressed into a p...

Abstract

The invention discloses an ecological plate made of straws and forestal residues and a method for preparing the ecological plate, which relate to the technical field of building decoration materials. The ecological plate consists of components, by weight, including from 45 to 48 parts of fine straw fibers, from 45 to 48 parts of fine forestal residue fibers, from 2 to 4 parts of adhesive, from 1 to 3 parts of flame retardant and from 1 to 3 parts of water repellent, and the ecological plate is processed by the aid of working procedures including chopping and crushing, preparing the fibers, beaching, adding the additives (the flame retardant, the water repellent and the adhesive), mixing and stirring, drying, briquetting and forming, adhering a decorative plate, forming a commercial plate and the like. The ecological plate has various advantages of low production cost, ecological property, environmental protection, high density and strength, wide material source, waterproofing, fireproofing and the like, is a medium and high-density composite fiber plate, can be widely applied to non-load bearing wall materials in frame structure and steel structure engineering, wall partitions for indoor decoration, wall partitions of factories, shopping malls and enclosing walls of plant areas, walls of trailer coaches and farm houses and the like, and is an environment-friendly product which is widely popularized according to wall modification policy of the country.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to an ecological board produced by utilizing straw and forestry residues and a preparation method thereof. Background technique [0002] According to data, according to my country's current development speed, it is estimated that the gap between domestic timber supply and demand will reach more than 150 to 200 million cubic meters in 2015; in 2020, it will reach 300 to 350 million cubic meters. According to statistics, the direct utilization rate of wood processing in my country is about 60%, and a large number of residues have not been well utilized. The annual urban waste produced in my country is about 6 billion tons, among which various types of wood waste (such as sawdust, bamboo and wood shavings, etc.) reach 60 million tons. If 10% of the wood waste can be recycled, 8.5 million cubic meters of wood can be saved every year. At the same time, our country...
