Preparation method of lightweight slats for building partition walls

Abstract

The invention provides a preparation method of light-weight battens for building partitions. The method comprises the following steps: (1) putting 62-66kg of fly ash, 310-330kg of cement, 2.5-3.15kg of polystyrene foamed particle and 304.7-439.6kg of pottery sand into a charging device, adding 150-170kg of water, stirring, adding a proper amount of physical expanding agent, and stirring for 10-15 minutes; (2) after installing a calcium silicate board, carrying out extrusion forming to obtain semifinished products; (3) discharging the light-weight battens, and stacking, wherein a plurality of light-weight battens form a stack, and a ventilation distance is left between every two adjacent stacks; and (4) naturally ventilating the stacks to obtain the light-weight batten finished products. The preparation method does not destroy the resources or cause secondary pollution, and is low in cost. The light-weight battens for building partitions produced by the preparation method have the advantages of light weight, high strength, heat insulation and sound deadening, and can utilize abundant fly ash and waste polystyrene board particles.

Description

technical field [0001] The invention relates to a preparation method of building materials, in particular to a preparation method of lightweight laths for building partition walls. Background technique [0002] With the development of science and technology, people have higher and higher requirements for the performance of buildings, not only require building materials to be light in weight, high in strength, heat insulation, noise reduction, flame retardant, but also require low cost of building materials, do not destroy resources, and do not cause secondary pollution; The traditional building partition wall materials are mainly made of solid bricks. When producing solid bricks, it is necessary to dig the ground to take soil and destroy the cultivated land. Not only is it poor in environmental protection, heavy in weight, and poor in sound attenuation and heat insulation, but also the production process is cumbersome and costly. high.
