Abstract
The invention relates to a manufacture method for straw bricks, in particular to a circulation method which includes the following steps of: firstly crushing the straws; after mixing the straws with a fish glue and concretes according to a certain proportion, arranging the straws into a heating furnace to be heated; then arranging the straws into a die and arranging the straws into a pressure resistance container; carrying out pressurizing, pressure keeping and discharging for 1 to 5 times on the pressure resistance container and finally taking out and opening the die.
Description
Affiliated technical field
The present invention relates to utilize agricultural crop straw to manufacture the preparation method of the method for construction material, particularly a kind of stalk brick.
Background technology
Agricultural crop straw is through after pulverizing, it is mixed among the magnesite stone flours such as magnesium chloride and magnesia and process gluing polymerization mold pressing, can make materials for wall, this is major ingredient with the magnesite stone flour, stalk is that the shortcoming of the polymerization mould pressing method of auxiliary material is: easy deformation and cost are higher and raw material supply difficult, therefore hinder the extensive utilization of agricultural crop straw as building materials, other also have to mix with adhesive with stalk and are pressed into flat sheet, but end is because of the too low and difficult bearing wall material of doing of its intensity.
Summary of the invention
The preparation method that the purpose of this invention is to provide a kind of stalk brick, the objective of the invention is to realize: be earlier the powder of straw that 15～30% agricultural crop straw is ground into 0.5～1.5mm with moisture content by following technical scheme, after above-mentioned powder of straw mixed according to 8: 1: 1 ratio of volume ratio with fish glue and concrete and stirring, put into and heat 10～60 minutes in the heating furnace, heating-up temperature is between 60～120 ℃, then this stalk mixture is put into the mould that has flexible and sealing device, again mould is put into the pressure vessel that is full of liquid pressure medium, pressure vessel carried out 1～5 time pressurization, the round-robin method of pressurize and pressure release, the pressure limit of each pressurization is between 50MPa～300Mpa, the time range of each pressurize is in 1 second～15 minute, mould is taken out and opens in pressure release afterwards at last.
Purpose of the present invention also comprises following technical scheme: employed agricultural crop straw also comprises the cauline leaf of wild plant.
The present invention compared with prior art has tangible advantage and good effect, adopt the present invention in being full of the pressure vessel of liquid pressure medium, to carry out the method that stalk is strengthened with the technology that waits static pressure, can evenly compress the gap of agricultural crop straw composition, when making its high compactionization, combine closely and be integral with fish glue and concrete, not only increase substantially the intensity that stalk is used as materials for wall, and overcome the shortcoming that the higher raw material difficulty of former stalk walling cost is asked, this stalk brick not only can be done the load-bearing material, and can make hollow stalk brick, thereby improve the effect of body of wall energy-saving heat preserving, maximally utilise this renewable resource of agricultural crop straw.
Claims (2)
1, a kind of preparation method of stalk brick is characterized in that, comprises the following steps:
It earlier is the powder of straw that 15～30% agricultural crop straw is ground into 0.5～1.5mm with moisture content, after above-mentioned powder of straw mixed according to 8: 1: 1 ratio of volume ratio with fish glue and concrete and stirring, put into and heat 10～60 minutes in the heating furnace, heating-up temperature is between 60～120 ℃, then this stalk mixture is put into the mould that has flexible and sealing device, again mould is put into the pressure vessel that is full of liquid pressure medium, pressure vessel carried out 1～5 time pressurization, the round-robin method of pressurize and pressure release, the pressure limit of each pressurization is between 50MPa～300Mpa, the time range of each pressurize is in 1 second～15 minute, mould is taken out and opens in pressure release afterwards at last.
2, the preparation method of stalk brick according to claim 1 is characterized in that, employed agricultural crop straw comprises the cauline leaf of wild plant.
