Description
Technical field
The present invention relates to building material technical field, and in particular to is incubated for a kind of made using sawdust as primary raw material
The method of material.
Background technology
Building energy consumption is to be only second to the third-largest energy resource consumption field of industry and traffic, in the past more than ten years, the neck
Domain, which is also released some and enumerated, arranges to reduce energy consumption, and the use of insulation material can largely improve this problem, still
The widely used insulation material of in the market has flammable properties and triggers repeatedly painful disaster, and based on this, it is high to work out cleaning
Effect, nonflammable light heat insulation material are particularly important, and China is an energy resource consumption big country, and consumption of wood is huge, are produced per annual meeting
Raw substantial amounts of sawdust, is used primarily in planting matrix production field.
The content of the invention
It is an object of the invention to provide a kind of the method for obtaining insulation material is made by primary raw material of sawdust.
The technical solution adopted by the present invention is, a kind of to make the method for obtaining insulation material by primary raw material of sawdust,
The insulation material makes raw material and is made up of charing sawdust, cement, bleeding agent, hydrophober, binding agent, defoamer；
The charing sawdust is made in such a way：
（1）By sawdust under 200-210 DEG C of carbonization temperature charing process 10-13 minutes, obtain nonflammable charing sawdust, but should
It is larger to handle obtained sawdust specific surface area, excellent insulation purpose can not be realized；
（2）The sawdust that charing obtains is crushed to more than 800 mesh with pulverizer, thereto by 13-15% weight than adding diethyl
100-120 times of liquid of hydramine, speed lapping mixing 18-20 minutes, make diethanol amine uniformly be wrapped under conditions of 120-130 DEG C
Charing obtains the surface of sawdust, finally gives charing sawdust, diethanol amine is uniformly wrapped in charing and is obtained the surface of sawdust and fills out
Fill in charing sawdust hole, significantly carry the thermal conductivity factor for reducing charing sawdust；
When specifically making insulation material,
（1）Count in parts by weight and 60-70 parts are carbonized into sawdust, 20-26 parts cement, 1-1.3 parts bleeding agent, 0.6-0.7 part hydrophobics
Agent, 1-1.5 parts binding agent, 0.2-0.25 parts defoamer are sent into mixer and are well mixed, by 1：0.42-0.46 weight ratio adds
Enter distilled water, 40-50 minutes are stirred under 30-35r/min low speed with mixer；
The bleeding agent is the phosphate containing specific short-chain alkyl；
The hydrophober is chlorinated paraffin；
The binding agent is vinyl acetate；
The defoamer is nano silicon；
Specific selected area update strategy agent is the phosphate containing specific short-chain alkyl；Hydrophober is chlorinated paraffin；Binding agent is acetic acid second
Alkene；Defoamer is nano silicon, it is ensured that charing sawdust fully mutually melts with cement to be mixed, and contributes to the generation of liquid phase,
Contact area increases between grain and particle, condenses closely, ensures that final mixed slurry more they tends to densification；
（2）The stir speed (S.S.) of mixer is improved to 80-85r/min, continues to stir 20-28 minutes, obtains mixed slurry；
（3）Mixed slurry is poured into pressure compressing in mould, compressing and is set as 1-1.5MPa, the press time is
13-15 minutes, after compressing, 30-35 minutes are conserved, during maintenance, rolled-up stock are handled with reference to ultrasonic wave, ultrasonic wave
Processing frequency is 80-85KHz, and treatment temperature is 30-32 DEG C, obtains insulation material；
During maintenance, maintenance material is handled with reference to the ultrasonic wave that frequency is 80-85KHz, and limit treatment temperature as 30-32
DEG C, enable to so that little particle coacervating large particle, further makes material tend to be fine and close, improve the compression strength of maintaining device；
Beneficial effect of the present invention is that the present invention is relatively low as the insulation material thermal conductivity factor that primary raw material makes to obtain using sawdust,
With excellent heat-insulating property, and there is preferable compression strength, former material used is mainly sawdust, and cost is cheap, belongs to discarded
Thing secondary use, there is the feature of environmental protection, whole processing procedure energy consumption is low, and equipment requirement is simple, can widely produce.
