Embodiment 1

[0025] Embodiment 1: The heat-insulating and sound-insulating sintered brick made of straw in this embodiment is made of ingredients and water. The initial addition of the above-mentioned water is 25%-35% of the total mass of the ingredients. The above-mentioned ingredients are made of the following raw materials in weight percentages Composition: straw powder 3-5%, standard coal powder 1-3%, clay 92-96%.

[0026] The water content of the straw powder is less than 10%, the water content of the standard coal powder is less than 10%, and the water content of the clay is less than 10%.

[0027] Such as figure 1 Shown, its preparation process comprises the following steps:

[0028] Step 1: Straw raw material processing, specifically, the straw raw material is pulverized by a pulverizer, and then vibrating and sieved by a sieve machine to obtain straw powder;

[0029] Step 2: batching, specifically, mixing the straw powder obtained in step 1 with standard coal and clay according ...

Abstract

The invention belongs to the technical field of building materials and especially relates to a heat-preservation and sound-insulation sintered brick produced from straw and a preparation method. The sintered brick is prepared from the following raw materials, by weight: 3-5% of straw powder, 1-3% of standard coal powder and 92-96% of clay. The preparation method includes the following steps: treating the straw raw material, blending the materials, stirring and aging the mixture, producing a green body, drying and pre-heating the green body, sintering the brick, cooling the sintered brick and taking the sintered brick out from the kiln. The brick is light in weight, is high in strength, has strong heat-preservation and sound-insulation effects, is high in compressive property, is simple in preparation process, is convenient to use, is high in resource utilization rate and low in production cost, is reduced in use amount of clay and can protect land resources. During the sintering process, the brick has a certain internal combustion property so that use quantity of coal is reduced, thereby reducing cost.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a thermal insulation and sound insulation fired brick made of straw and a preparation process. Background technique [0002] At present, clay sintered bricks are made of clay (including shale, coal gangue and other powder materials) as the main raw material, which is processed, shaped, dried and roasted by mud. The production is time-consuming and laborious. The production process requires a large amount of land and coal resources. The production efficiency is low, waste bricks such as underfire or overfire are prone to occur, and the quality of the brick body is relatively heavy, the heat preservation and sound insulation effects are poor, the antifreeze ability is weak, the production process is cumbersome, and the environmental protection is not enough. , discloses an energy-saving and environment-friendly straw brick and a preparation method thereof, which is produ...
