Abstract
The invention discloses a composite material capable of substituting solid wood. The composite material is basically prepared through the following raw materials by weight percent: 70 to 95 percent of herbaceous plant fibers, waste paper or solid wood leftovers and 30 to 5 percent of unsaturated polyester resin binder. The invention also discloses a preparation method of the composite material. The preparation method comprises the following steps of firstly dehydrating the herbaceous plant fibers, waste paper or solid wood leftovers to the moisture content of 2 to 5 percent, and then crushing the herbaceous plant fibers, waste paper or solid wood leftovers into granular materials with particle size of 1mm to 3mm; taking 70 t 95 percent of the granular materials and 30 to 5 percent of unsaturated polyester resin binder, preparing the unsaturated polyester resin binder to a solution, and uniformly stirring the unsaturated polyester resin binder solution and the granular material; adding the stirred material into a mold, and die-casting molding the material; opening the mold to trim after the material is stereotyped to obtain the composite material. The product is environment-friendly, the fracture problem of the solid wood when suffering the spot impact force can be solved, and leftovers solid-wood or medium-high-fibrous plate and complicated processing problem can be completely overcome; the energy consumption is low, the strength is higher, the molding is not limited, and the production process is shortened.
Description
Technical field
The present invention relates to a kind of composite and preparation method thereof.
Background technology
Cause global warming problem now, except earth overpopulation, carnivorous animal husbandry develop rapidly, the overcut of forest and trees, the natural mechanism of freshwater resources protection declines, and is also one of epochmaking reason.Therefore,, outside the new petroleum replacing energy of global development, the exploitation that substitutes perennial arbor class solid wood for the plant that uses short-term growth is also done one's utmost with research.Wherein, especially with the hottest network of development and use research of the non-consumption Activities of Some Plants fiber (as rice straw, straw, cornstalk etc.) of food plant, this type of material was discarded object originally, or directly rubbed recurrence farmland, as fertilizer, but treatable quantity can not be too much, or after the phase is natural drying, a fire, by it processing, forms plant ash, and reverting to farmland becomes the minimum fertilizer of Denging.
Summary of the invention
In order to overcome the deficiencies in the prior art, an object of the present invention is to provide a kind of composite that replaces solid wood, to increase the application of herbaceous plant short fiber, to replace the use of arbor class solid wood, reduce deforestation.
Another object of the present invention is the preparation method that a kind of composite of this replacement solid wood will be provided, and to improve manufacturing technology and colloid, reduces energy consumption.
The technical solution adopted for the present invention to solve the technical problems is:
Replace a composite for solid wood, it is characterized in that it is to be prepared from by the raw material of following weight ratio substantially: herbaceous plant fiber or waste paper or solid wood leftover pieces 70-95%, unsaturated polyyester adhesive 30-5%.
The string of the non-consumption part that described herbaceous plant fiber is food plant.
Described unsaturated polyyester adhesive can adopt two kinds of different binder combination to form.
It comprises the steps: first herbaceous plant fiber or waste paper or solid wood leftover pieces to dewater to water content 2-5%, then to be ground into particle diameter be the granular of 1-3 ㎜; By weight, get granular herbaceous plant fiber or waste paper or solid wood leftover pieces 70-95%, unsaturated polyyester adhesive 30-5%, by unsaturated polyyester adhesive make solution and and herbaceous plant fiber or waste paper or solid wood leftover pieces stir; The material being stirred is added in mould to die cast; After sizing, open die trimming and obtain this composite.
The string of the non-consumption part that described herbaceous plant fiber is food plant.
Described die cast is to adopt 100-300 t hydraulic press to carry out die casting to the material in mould.
The shape of described mould is predefined according to the shape of product.
Herbaceous plant fiber: make a general reference all from non-plant or the part of falling trees and can obtain, obtain non-soluble fiber in a short time through fermentation method.As: rice straw, straw, cornstalk, non-edible part of sugarcane etc.
Unsaturated polyyester adhesive of the present invention can adopt product conventional on market, as: PUR adhesive such as LSE. environment-friendly resin (EnvironmentalResin), EPMC. environment-friendly resin, EVA, SBS and SIS etc.
Solvent can adopt alcohol, styrene etc.
The invention has the beneficial effects as follows: the raw material that 1, the present invention adopts is term growth, and be non-edible part, do not need the felling need to be through the trees of many decades generation, hundred times of environmental protection efficiency be counted above; Can solve the problem that solid wood forms cracking in the time being subject to a some impulsive force; The present invention can adopt mould straight forming, overcomes the leftover pieces of solid wood or middle high fibre plate and complicated processing problems completely; Low energy consumption, intensity are stronger, moulding is more unrestricted, processing procedure shortens.
Below in conjunction with embodiment, the present invention is further described.
Detailed description of the invention

Unsaturated polyyester adhesive in above-described embodiment can adopt product conventional on market, as: PUR adhesive such as LSE. environment-friendly resin (EnvironmentalResin), EPMC. environment-friendly resin, EVA, SBS and SIS etc.
The present invention is because adopting two component cure adhesives, and therefore thickness can infinitely extend, and reaches the function the same with solid wood products.Can be fabricated into the product that paper products cannot be reached so far: product or the parts of making furniture or Building class main structure.
When the present invention adopts two component cure adhesive, hardening time capable of regulating, moisture-free, reaction can be from 0 thermal energy consumption, but when accelerating moulding and ensure product size, asks for stating with surface drying, energy consumption is the 20-25% of current paper products.But the 3-5 that product strength is paper products doubly.(according to colloid formula and content and determine)
Making body is that paper products is incomparable.
Paper products is in liquid, drag for and lean on paper pulp sedimentation, is to need larger gradient to provide paper pulp sedimentation to use to vertical walls.
Product of the present invention, because adopting resin, with micro-wet moulding, only needs the material feeding the same with plastic product and draw taper.
The present invention is taking resin as adhesive, and therefore, not only water proofing property is strong, and effects on surface is coated with stronger solvent resistance and higher adhesive force.This is that general paper products cannot be reached.
