Abstract
The invention relates to a method of making nonbearing and insulating building blocks from broomcorn straw, and it is a preparing technology of architectural wall materials, which comprising the following steps: drying broomcorn straws after harvest in the open; wiping off the leaf of the broomcorn straws, drying them and making moisture percentage less than 3%; cutting up the broomcorn straws to 2-5 cm; mixing broomcorn straws with polystyrene granules proportion as 350-450:1; putting the mixture into blocks dies, and blowing aqueous vapour of 90 DEG C into the mixture in the dies, and making polystyrene granules froth and bulg to fill of the dies, simultaneity, making broomcorn straws and polystyrene granules adhere to one another and form whole; stripping to get nonbearing and insulating building blocks. The blocks made with the method settles the problems of large load of the building body and worse effect of thermal and sound insulation
Description
Technical field
The present invention relates to a kind of technology of preparing of construction material, particularly relate to a kind of making method of utilizing broomcorn straw to make the non-bearing building heat preservation blocks.
Background technology
The non-bearing building block of construction wall at present mostly is mineral-type materials greatly, and its intensity is better, but insulation, defening effect are relatively poor, and unit weight is big, has increased the load of building body.Can not arbitrarily move during construction, simultaneously, China has a large amount of agricultural crop straws not obtain reasonable use every year.
Summary of the invention
The object of the present invention is to provide a kind of method of manufacturing non-bearing heat-preserving building block by sorghum straw, broomcorn straw and polystyrene after this method utilization oven dry are produced building heat preservation blocks for main raw material(s), the load that has solved the building body is big, insulation, the relatively poor problem of defening effect.
The objective of the invention is to be achieved through the following technical solutions:
A kind of method of manufacturing non-bearing heat-preserving building block by sorghum straw, described manufacturing non-bearing heat-preserving building block by sorghum straw is made according to the following steps:
1) the broomcorn straw natural drying after will gathering in the crops is earlier done;
2) broomcorn straw that natural drying is done is removed remaining leaf, dry to water ratio below 3%;
3) broomcorn straw after will drying shred to length be 2～5cm;
4) be 350～450 in the Chinese sorghum straw: polystyrene is that 1 ratio is mixed the disintegrating Chinese sorghum stalk with granules of polystyrene;
5) broomcorn straw and granules of polystyrene compound are put into building block mould;
6) compound in the mould is fed 90 ℃ water vapour, make the rapid foaming and intumescing of granules of polystyrene be full of space in the mould, make the broomcorn straw in the mould, the mutual adhesion of granules of polystyrene after the foaming simultaneously, form an integral body;
7) material after the form removal is the non-bearing building heat preservation blocks.
Above-mentioned pulverizing is meant the machinery chopping.
Above-mentioned oven dry is meant uses industrial drying machine drying.
Advantage of the present invention and effect are:
1. the building block of the inventive method manufacturing is in light weight, has reduced the load of building body.
2. building block sound insulation, the high insulating effect made of the inventive method.
3. the inventive method can effectively be utilized the broomcorn straw resource.
