Embodiment 1

[0020] 1. Preparation of halogen powder solution: when the ambient temperature is 5-10°C, add 900kg of halogen powder into 1000kg of water, stir to make it fully dissolve and set aside.

[0021] 2. Prepare the mixed solution: add 8kg of anti-halogen compounding agent to the brine solution, stir and dissolve, then add 8kg of anti-corrosion compounding agent for use.

[0022] 3. Weigh 11kg of straw powder (70-80 mesh) and 18kg of lightly burnt powder and pour it into a blender to mix evenly, then inject 1.9 times the weight of the mixed solution, and stir to form a thinner.

[0023] 4. After injecting the thinner material into the vertical mold machine, layer 4kg of glass fiber mesh cloth according to the amount, and form and harden the thinner material, and then cure it for one week to become the finished product.

Embodiment 2

[0025] 1. Preparation of halogen powder solution: when the ambient temperature is 10-20°C, add 500kg of halogen powder into 1000kg of water, stir to make it fully dissolve and set aside for use.

[0026] 2. Prepare the mixed solution: add 8kg of anti-halogen compounding agent to the brine solution, stir and dissolve, then add 8kg of anti-halogen compounding agent for use.

[0027] 3. Weigh 16.5kg of straw powder (70-80 mesh) and 13.5kg of lightly burnt powder, pour them into a blender and mix well, then inject 1.9 times the weight of the mixed solution and stir to form a thinner material.

[0028] 4. After injecting the thinner material into the formwork, layer 3kg of glass fiber mesh cloth into layers according to the amount, and form and harden it by bonding the thinner material densely. After one week of curing, the finished product is obtained.

Embodiment 3

[0030] 1. Prepare the halogen powder solution. When the ambient temperature is 20-30%, add 450kg of halogen powder into 1000kg of water, stir to make it fully dissolved and set aside.

[0031] 2. Prepare a mixed solution (with step 2 in Example 1 or 2).

[0032] 3. Weigh 20kg of straw powder (70-80 mesh) and 11kg of lightly burned powder, pour them into a blender and mix well, then inject 1.9 times the weight of the mixed solution and stir to form a thinner.

[0033] 4. After injecting the thinner material into the formwork or the vertical mold machine, 2kg of glass fiber mesh cloth layered cloth net is bonded and compacted by the thinner material according to the amount, and it is cured for one week to be the finished product.

[0034] The content of magnesium oxide in the said pumice powder should be greater than 85%; the said glass fibers are low-alkali or alkali-free glass fiber mesh cloth. The preparation of the halogen powder solution is to determine the amount of halog...

Abstract

The present invention provides a kind of building material with stalk as main material and its production process. The building material is produced with stalk powder, light burnt powder, glass fiber, halide powder solution, ferric alum, Gelaihan salt, sodium phosphate hydrate, calcium carbonate, oxalic acid, and magnesium hydroxide. It has high stalk utilization, low cost and simple production process, and may be used as light building material for wall, ceiling, column, window and door pocket, etc.

Description

technical field [0001] The invention relates to a building material mainly made of straw and a preparation method thereof. Background technique [0002] For thousands of years, people have excavated a large number of clay and fired solid bricks or hollow bricks as wall materials for houses and various buildings. Due to years of digging and burning bricks, a large amount of arable land has been destroyed, and the non-renewable land resources on which human beings depend have been seriously damaged. At the same time, the fuel for burning bricks is mainly coal, which, in addition to large usage and high cost, causes environmental pollution more importantly. In addition, most farmers either sell the straw to paper mills or burn it on the spot, which causes great waste and seriously pollutes the atmosphere, which not only affects the normal driving of cars and planes, but also easily causes fires. In recent years, some enterprises or individuals have sought to use the crushed s...
