Preparation process for sintering brick by using straws and clay

Abstract

The invention discloses a preparation process for sintering a brick by using straws and clay, relating to the technical field of building materials. The preparation process comprises the following steps: (1) weighting the clay, smashed plant straws and a combustion improver according to the mass ratio of 10:7:1, and uniformly mixing the raw materials to obtain a material a for later use; (2) adding wood and plastic flour, and uniformly mixing the wood and plastic flour and the material a to obtain a material b, wherein the wood and plastic flour accounts for 1% of the total mass of the material a; (3) placing the material b into stirring equipment for stirring for 3-6h, and adding water in a stirring process to obtain a material c, wherein the water accounts for 2% of the total mass of the material b; (4) placing the material c into forming equipment for extrusion molding, and preparing an unburned brick according to a certain specification to obtain a material d for later use; (5) transferring the material d into refrigerating equipment for freezing treatment at the temperature of less than 0 DEG C for 2-3h to obtain a material e; (6) naturally airing the material e, and then, sintering the material e in a kiln to obtain the brick. The brick prepared by using the preparation process has the specific advantages such as low heat conductivity and heat transfer coefficient, light weight, high strength, fireproofness, acid and alkaline resistance, sound insulation, environmental friendliness, simplicity and convenience in construction and the like of a foamed concrete block and also has the advantage of pressure bearing property of the traditional internal combustion clay brick.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a production process of sintered bricks using straw and clay. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops, and usually refers to the remaining parts of wheat, rice, corn, potatoes, oilseeds, cotton, sugar cane and other crops after harvesting seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, and is a multi-purpose renewable biological resource. [0003] Chinese farmers have a long history of using crop stalks. However, due to the low level of agricultural production and low output in the past, the amount of stalks was small. Apart from a small amount of stalks being used for gaskets, feeding livestock, and some for composting, most of them were used as fuel. burnt. [0004] At present, there a...

Problems solved by technology

[0004] At present, there are many kinds of bricks used in construction, which can be roughly divided into two categories, one is load-bearing bricks, and the other is non-load-bearing bricks. The cost is relatively low; most of the non-load-bearing bricks are lightweight bricks, including foam bricks and hollow bricks. Light bricks have high thermal insulation performance, which can reduce the foundation design and reduce the cost of basic construction, but the frame structure design needs to be strengthened, and the cost is often higher. high
