Problems solved by technology

One is to collect a large amount of loess from the fields, which will destroy land resources and reduce agricultural land, causing many places to be full of potholes; A large amount of smog that occurs during manufacturing also seriously pollutes the atmosphere; the loess bricks fired are heavy in weight and high in transportation costs, and being used for building walls increases the total weight of the building and greatly reduces the payload of the building; at the same time , the labor intensity of digging, firing, transporting and building walls is very high
Therefore, using loess to make bricks destroys the natural ecological environment and does not conform to the national environmental protection policy

Embodiment Construction

[0012] Take the raw material straw or wheat straw to cool and dry to remove water; then spray 902 glue as a binder on it, stir evenly, the added binder can be added according to the conventional amount, so that the straw can be bonded; Then put it into the brick mold and squeeze it, take out the movable mold (upper mold) after pressing, and then put straw or wheat straw mixed with 902 glue into the extruded space until the size is length, width, After reaching the requirements of the brick, it is consolidated and shaped.

[0013] During use, when building a wall in a building with a frame structure (which is almost all the case now), the straw bricks prepared by the present invention are staggered and built layer by layer, the same as the original earth bricks, only the upper and lower floors each The two adjacent grass bricks are inserted obliquely with wood screws and fixed without cement or yellow sand. The walls are solid.

[0014] According to the test, in the dead of n...

Abstract

A process for preparing straw bricks with dead weight, sufficient strength and high sound and heat isolating effect includes mixing rice straw or wheat straw with adhesive, and die pressing.

Description

technical field [0001] The invention relates to a brick and a preparation method thereof, in particular to a straw brick and a preparation method thereof. Background technique [0002] Before the present invention, the used brick of existing building mostly forms by firing loess. The defects of this brick are obvious. One is to collect a large amount of loess from the fields, which will destroy land resources and reduce agricultural land, causing many places to be full of potholes; A large amount of smog that occurs during manufacturing also seriously pollutes the atmosphere; the loess bricks fired are heavy in weight and high in transportation costs, and being used for building walls increases the total weight of the building and greatly reduces the effective load of the building; at the same time , The labor intensity of digging, firing, transporting, and building walls is very high. Therefore, using loess to make bricks destroys the natural ecological environment and d...
