Abstract
The invention discloses a kind of method of stalk manufacture insulation blocks, this method utilizes the corn stover after drying and polystyrene is that main raw material(s) produces building heat preservation blocks, and the load for solving building body is big, the poor problem of heat preservation, sound insulation effect.
Description
Technical field
The present invention relates to a kind of methods of stalk manufacture insulation blocks.
Background technique
The non-bearing building block of construction wall is mostly mineral-type materials, and intensity is preferable, but keep the temperature, sound insulation effect it is poor,
And bulk density is big, increases the load of building body.Building block has fly ash silicate building block, common coagulation by material point
Native building-block, gangue silicate hollow block etc..Meanwhile China has a large amount of agricultural crop straw not closed every year
The utilization of reason.
Summary of the invention
The purpose of the present invention is to provide a kind of method of stalk manufacture insulation blocks, this method utilizes the corn after drying
Stalk and polystyrene are that main raw material(s) produces building heat preservation blocks, and the load for solving building body is big, heat preservation, sound insulation effect compared with
The problem of difference.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of method of stalk manufacture insulation blocks:
1) first the corn stover natural drying after harvest is done；
2) corn stover for doing natural drying, is dried to moisture content below 5%；
It 3) is 2~5cm by the shredding corn stalk after drying to length；
4) smashed corn stover is mixed with granules of polystyrene by a certain percentage；
5) appropriate mixture is put into building block mould；
6) it is passed through 100 DEG C of vapor to the mixture in mold, makes the rapid foaming and intumescing of granules of polystyrene full of in mold
Space, while making the mutual adhesion of the corn stover in mold, the granules of polystyrene after foaming, form an entirety；
7) material after-demoulding is non-bearing building heat preservation blocks.
Above-mentioned crushing refers to mechanical chopping.
Above-mentioned drying refers to industrial drying machine drying.
The advantages and effects of the present invention are:
1. the building block of the method for the present invention manufacture is light-weight, reduce the load of building body.
2. the building block sound insulation of the method for the present invention manufacture, heat insulation effect are good.
3. the method for the present invention can efficiently use maize straw resource.
Specific embodiment
Embodiment 1
First the corn stover natural drying after cotton harvesting is done, by natural drying do corn stover or after be dried to moisture content
It, will be smashed by weight 400: 1 ratio 3% hereinafter, it is 2~5cm that the corn stalk powder after drying, which is broken to length,
Corn stover is mixed with granules of polystyrene, and mixture is put into building block mould, until being full of mold.To mixed in mold
The vapor that material is passed through 100 DEG C is closed, the atmospheric pressure 2 minutes of water vapour pressure 3.5 in mold is kept, keeps granules of polystyrene fast
Fast foaming and intumescing glues the cotton stalk in mold, the granules of polystyrene after foaming mutually full of the space in mold
Even, an entirety is formed.Material after demoulding is non-bearing building heat preservation blocks.
Embodiment 2
First the corn stover natural drying after harvest corn is done, by natural drying do corn stover or after be dried to it is aqueous
For rate 5% hereinafter, it is 2-5cm that the corn stalk powder after drying, which is broken to length, by weight 300: 1 ratio will be smashed
Corn stover is mixed with granules of polystyrene, and mixture is put into building block mould, until being full of mold.To mixed in mold
The vapor that material is passed through 100 DEG C is closed, the atmospheric pressure 2 minutes of water vapour pressure 3.5 in mold is kept, keeps granules of polystyrene fast
Fast foaming and intumescing glues the corn stover in mold, the granules of polystyrene after foaming mutually full of the space in mold
Even, an entirety is formed.Material after demoulding is non-bearing building heat preservation blocks.
Claims (3)
