Abstract
The invention discloses a method for manufacturing non-load-bearing heat-insulation building blocks from corn straw. The method has the advantages that the heat-insulation building blocks are manufactured from main raw materials which include the dried corn straw and polystyrene, and accordingly problems of high load and poor heat-insulation and sound-insulation effects of buildings can be solved.
Description
Technical field
The present invention relates to a kind of technology of preparing of construction material, particularly relate to a kind of preparation method utilizing maize straw to manufacture non-bearing building heat preservation blocks.
Background technology
The non-bearing building block of current construction wall is mostly mineral-type materials, and its intensity better, but is incubated, defening effect is poor, and bulk density is large, adds the load of building body.Building block divides by material, has fly ash silicate building block, ordinary concrete hollow block, gangue silicate hollow block etc.Meanwhile, China has a large amount of agricultural crop straws reasonably not utilized every year.
Summary of the invention
A kind of maize straw is the object of the present invention is to provide to manufacture the method for non-bearing heat-preserving building block, the method utilizes the maize straw after drying and polystyrene to produce building heat preservation blocks for main raw material(s), the load solving building body is large, the problem that insulation, defening effect are poor.
The object of the invention is to be achieved through the following technical solutions:
A kind of maize straw manufactures the method for non-bearing heat-preserving building block:
1) first the maize straw natural drying after results is done;
2) maize straw that natural drying is dry is removed remaining leaf, dry to moisture content below 3%;
3) by dry after shredding corn stalk to length be 2 ~ 5cm;
4) by a certain percentage the maize straw after pulverizing is mixed with granules of polystyrene;
5) appropriate compound is put into building block mould;
6) compound in mould is passed into the steam of 100 DEG C, make the rapid foaming and intumescing of granules of polystyrene be full of space in mould, make the mutual adhesion of granules of polystyrene after the maize straw in mould, foaming simultaneously, form an entirety;
7) material after-form removal is non-bearing building heat preservation blocks.
Above-mentioned pulverizing refers to machinery chopping.
Above-mentioned oven dry refers to uses industrial drying machine drying.
Advantage of the present invention and effect are:
1. the building block of the inventive method manufacture is lightweight, decreases the load of building body.
2. the inventive method manufacture building block sound insulation, high insulating effect.
3. the inventive method effectively can utilize maize straw resource.
Detailed description of the invention
Embodiment 1
First the maize straw natural drying after harvest corn is done; the maize straw that natural drying is dry removes remaining leaf; then dry to moisture content below 3%; it is 2 ~ 5cm that corn stalk powder after oven dry is broken to length; maize straw after pulverizing mixes with granules of polystyrene by the ratio by weight 500: 1; compound is put into building block mould, until be full of mould.Compound in mould is passed into the steam of 100 DEG C; water vapour pressure 1.5 atmospheric pressure 1 minute in maintenance mould; the rapid foaming and intumescing of granules of polystyrene is made to be full of space in mould; make the mutual adhesion of granules of polystyrene after the maize straw in mould, foaming simultaneously, form an entirety.Material after form removal is non-bearing building heat preservation blocks.
Embodiment 2
First the maize straw natural drying after harvest corn is done; the maize straw that natural drying is dry removes remaining leaf; then dry to moisture content below 3%; it is 2-5cm that corn stalk powder after oven dry is broken to length; maize straw after pulverizing mixes with granules of polystyrene by the ratio by weight 400: 1; compound is put into building block mould, until be full of mould.Compound in mould is passed into the steam of 100 DEG C; water vapour pressure 1.5 atmospheric pressure 1 minute in maintenance mould; the rapid foaming and intumescing of granules of polystyrene is made to be full of space in mould; make the mutual adhesion of granules of polystyrene after the maize straw in mould, foaming simultaneously, form an entirety.Material after form removal is non-bearing building heat preservation blocks.
Claims (3)
