Abstract
The present invention is to utilize high temperature technology and chemical method that corn straw carries out pyrolysis processing, solves corn straw as problems such as can going mouldy and damage by worms during building masonry material.Corn straw is as a kind of natural macromolecular material, because himself containing abundant nutrient substance, when applying as building masonry material, the harm can gone mouldy and damage by worms so that it is occur that thermal and insulating performance declines, intensity declines the even phenomenon such as overall structure destruction.By high temperature technology, corn straw is carried out pyrolysis processing, both on the premise of having can guarantee that the advantages such as insulation that corn straw self is good, heat insulation and sound insulation, the phenomenon such as it can be overcome again in use to go mouldy and damage by worms, thus improve that corn straw is bad as durability during building masonry material and the problem such as economic benefit is the best.
Description
Technical field
The present invention relates to building engineering field, be a kind of corn plant fiber masonry material with self-heat conserving, high-durability
Material way.
Background technology:
Corn straw is a kind of natural macromolecular material, has good heat insulating effect.Its Main Ingredients and Appearance cellulose, half is fine
Dimension is plain, lignin and a small amount of extract composition, and during using corn straw as building masonry material, straw meeting is because self is foster
Part is gone mouldy, and the corn straw after going mouldy self is declined by corrosion failure, weatherability and durability, the most whole masonry material
Destruction disintegrated by material.The present invention utilizes harmless processing method to process corn straw, and the corn straw after process is with special
Inorganic coagulation material carries out mix and makes green material.
Summary of the invention:
The present invention seeks to utilize high temperature technology and chemical method that corn straw carries out pyrolysis processing, solve corn straw
As problems such as can going mouldy and damage by worms during building masonry material.Corn straw is as a kind of natural macromolecular material, because of it
Self contain abundant nutrient substance, when applying as building masonry material, the harm can gone mouldy and damage by worms, make
It occurs that thermal and insulating performance declines, intensity declines the even phenomenon such as overall structure destruction.By high temperature technology to Semen Maydis
Straw carries out pyrolysis processing, on the premise of both having can guarantee that the advantages such as insulation that corn straw self is good, heat insulation and sound insulation, again can
The phenomenon such as overcome it in use to go mouldy and to damage by worms, thus improve corn straw as durable during building masonry material
Property the problems such as bad and economic benefit is the best.
Corn straw make 15MM ~ 50MM thickness not wait aggregate, by 2.50MM, 5.00MM, 10.00MM,
16.00MM, 20.00MM, 25.00MM, 31.50MM, 40.00MM, 50.00MM square hole screen sieves, and corn straw is thin
Degree modulus controls between 15 ~ 20.Aggregate after sieving is carried out pyrolysis processing, and pyrolysis temperature is at 490 DEG C--between 550 DEG C.
In order to prevent corn straw from burning in processing procedure, injecting purity in processing stove is the nitrogen of more than 90%.After process
Corn straw main chemical be, SiO2Content is 32 ~ 45%, Al2O3Content is 1 ~ 4%, Fe2O3Content is 0.7 ~ 3%, K2O
Content 2.2 ~ 5.4%, Na2O content is less than 0.09, and corn straw parses tar, CO simultaneously2、CO、CH4、H2Etc. substantial amounts of gas
Body, gas, after water-cooled or steam cool down, can be fabricated to straw vinegar liquid.
In order to improve the compatibility between fiber and Binder Materials, the straw concentration that pyrolysis is completed is 25 ~ 40% alkenes
The polymer solution of monomer soaks, and soak time is 1 hour, makes stalk material infiltration hygroscopic, easy, the most bonding etc..Soak
After straw dry, control at moisture content less than less than 8%.It is being the graft cyanoethyl of 10 ~ 15% by employing concentration simultaneously
Modified fillers therefor improves wood plastic composite hot strength, improves the compatibility of fiber and hydrophobic polymer, and stretching is disconnected simultaneously
Split percentage elongation the highest;And water mix liquor-saturated polypropylene grafted with maleic acid is used for processing the wood fiber, improves Plant fiber and is combined
Material and the compatibility of inorganic coagulation material.
Materials such as giobertite, tripoli Ore, Talcum, serpentine and meerschaums, it is crushed to 10mm with jaw crusher
Hereinafter, grinding about 30min in putting into ball mill, sieving with 0.08 square hole screen, residue on sieve can not be more than 10%, and 800
DEG C ~ 950 DEG C at calcine, make epoxy glue gel material, its part ratio is for 1:0.1 ~ 0.2:0.1 ~ 0.03:0.1 ~ 0.2:0.1 ~ 0.2, main
Wanting chemical analysis is M-S-H Binder Materials.The Binder Materials made and water carry out mix, and cement-water ratio is 2.5 ~ 3.3.Mixing is good
Cement mortar subtracts at addition sodium tripolyphosphate 0.2 ~ 0.3 part, sodium pyrophosphate 0.12 ~ 0.15, sodium dihydrogen phosphate 0.2 ~ 0.3 and polycarboxylic acids
