Abstract
The invention relates to a straw fiber board, comprising the materials in weight ratio as follows: crop straw 60% to 70%, starch 8% to 15%, alum 2% to 6%, table salt 1% to 4%, brown sugar 2% to 3%, moisture resistant agent 4% to 6%, and water 10% to 20%. In the invention, various crop straws are used as raw materials, and starch is used as adhesive. A moisture resistant agent is added into the material of the straw fiber board, and the sheet is provided with a better moisture resistant function; the straw fiber board is made by artificial pressurizing and heating, and the large hot press is not needed. The straw fiber board has the advantages of innocuity and no taste, better adhesive effect, hardness, functions of planning, sawing, nailing and bonding, wide application range, light volume and non-pollution, which is used for making various furniture, windows and doors, lightweight wallboards, fireproof boards and packing boxes.
Description
Technical field
The present invention relates to a kind of sheet material of making of stalk, be specifically related to a kind of straw fiber board and preparation method thereof.
Background technology
Now furniture, door and window, wallboard, and most glued board, fiberboard, calcium-plastic board and materials such as plasterboard and straw fiber board of using of decorative board material, above-mentioned finishing material price is more expensive, humidity resistance is all undesirable, and the adhesive that adopts mainly contains phenol glue or urea-formaldehyde glue, the formaldehyde that it discharged jeopardizes health, and environmental-protecting performance is relatively poor.
Publication number is CN1570275, and patent name is: the compound high medium density fibre board (MDF) manufacture method of environment-friendly type vegetation, and this method is by processing stalk pulverizing, defibrination, defibre, execute urea-formaldehyde resin adhesive, preparation stalk fiber sizing; Use the timber defibrination again, defibre applies urea-formaldehyde resin adhesive, and preparation timber fiber sizing mixes the timber fiber sizing in proportion with the stalk fiber sizing; The fiber sizing moulding of mating formation is hot pressed into the plain plate of high medium density fibre board (MDF); Plain plate is fallen the aldehyde process chamber and reduces content of formaldehyde falling the aldehyde process chamber.
Summary of the invention
The object of the present invention is to provide a kind of cheap, the environment-friendly type straw fiber board that humidity resistance is good.
Technical solution of the present invention is: straw fiber board is to be made by the raw material of following weight ratio: agricultural crop straw 60-70%, starch 8-15%, alum 2-6%, salt 1-4%, brown sugar 2-3%, anti-blushing agent 4-6% and water 10-20%.
Preferably: agricultural crop straw 60.5%, starch 10%, alum 3%, salt 2%, brown sugar 1.5%, anti-blushing agent 3% and water 20%.
The preparation method of straw fiber board of the present invention, with crushed stalk to 2-5mm, starch, alum, salt, brown sugar and water mix, be heated to 50-60 ℃, add anti-blushing agent and stalk and stir, the raw material that stirs is put into mould, dry after artificial pressurization or the mechanical extrusion forming, bake out temperature 50-80 ℃, time 15-20 hour, come out of the stove promptly.
Straw fiber board of the present invention is made raw material with various agricultural crop straws, as: straw, straw, jowar stalk, cornstalk, shell etc.Starch, alum, salt, brown sugar and water is mixed makes adhesive together, nonpoisonous and tasteless, bonding effect is good.Add anti-blushing agent in the raw material of the present invention, make sheet material have better moisture-proof function; Sheet material is hard, function such as can dig, saw, follow closely, glue, and has wide range of applications, and can be used for making various furniture, door and window, Light trabs, PLASTIC LAMINATED and packing case etc., adopts artificial pressurized, heated promptly to can be made into, and does not need large-scale Hot Press.This sheet material body is light, tasteless, pollution-free.
The specific embodiment
Make straw fiber board of the present invention and get 60 kilograms of raw material 2-5mm agricultural crop straws, 10 kilograms of starch, 3 kilograms in alum, 2 kilograms of salt, 1.5 kilograms of brown sugar, anti-blushing agent anhydrous calcium chloride or other timber with 20 kilograms in 3 kilograms of anti-blushing agents and water.Starch, alum, salt, brown sugar and water are mixed, be heated to more than 50 ℃, add anti-blushing agent and stalk, then above-mentioned raw materials is put into mixer together, stir, the raw material that stirs is put into mould, artificial extrusion forming, pressure is 90-180kg/m
2, put into drying oven oven dry then, temperature 50-80 ℃, time 15-20 hour, come out of the stove and do edging and handle and be finished product.
Claims (3)
