Process for micro foaming of assembly type building light wallboard

Abstract

The invention relates to a process for micro foaming of an assembly type building light wallboard. The process for micro foaming comprises a step (1) of slurry preparation, wherein the slurry is prepared from 600-700 weight parts of ordinary Portland cement, 15-20 weight parts of ceramsite, 35-50 weight parts of coal cinder, 55-80 weight parts of fly ash, 8-10 weight parts of polyester fiber, 800-1000 weight parts of water, 30-40 weight parts of light thermal-insulating filler, 6-8 weight parts of cocoanut cellulose, 0.2-0.4 weight parts of cement enhancer, 0.8-1 weight part of curing agent and 0.1-0.3 weight part of cement foaming agent; a step (2) of foaming; a step (3) of preparation of anti-cracking gridding cloth; a step (4) of solidification forming; and a step (5) of aftertreatment. The process for micro foaming of the assembly type building light wallboard has the advantages that the light materials such as the ceramsite and the cocoanut cellulose are adopted and prepared into the light wallboard high in combination property together with the ordinary Portland cement, the coal cinder, the fly ash and other auxiliaries according to a certain proportion.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a light-weight wallboard for prefabricated buildings [0002] micro-foaming process. Background technique [0003] At present, the wall panels are generally made of bricks, and the construction period is long. At present, some wall panels for internal partitions generally use light steel keels in the middle, and gypsum boards on both sides. High-grade partition walls, that is, add sound insulation in the middle of the gypsum boards. Cotton and other materials, although this kind of wallboard has a low capacity, its sound insulation effect is not very good, its heat insulation is very poor, and its service life is relatively short. The load-bearing capacity of the board wall is low, and it is dangerous to hang the wall-mounted TVs that are popular now.

Problems solved by technology

[0003] At present, the wall panels are generally made of bricks, and the construction period is long. At present, some wall panels for internal partitions generally use light steel keels in the middle, and gypsum boards on both sides. High-grade partition walls, that is, add sound insulation in the middle of the gypsum boards. Cotton and other materials, although this kind of wallboard has a low capacity, its sound insulation effect is not very good, its heat insulation is very poor, and its service life is relatively short. The load-bearing capacity of the board wall is low, and the popular wall-mounted TVs are more dangerous to hang on

[0004] In view of the above phenomenon, the patent CN 103058702 A discloses a preparation method of lightweight wallboard, mixing and stirring inorganic gelling material, light insulation filler, mineral powder and water for 1-2 minutes, and then putting the fiber reinforcement material into the stirring 1-2 minutes, then put the waterproofing agent in and stir for 1-2 minutes, then beat the physical foaming agent into the foam and put it into the stirring for 0.5-1 minute, then pour the stirred slurry into the formwork, roll it on Rest at 20-30°C for 24 hours, then remove the mold, and place it at room temperature for more than 7 days after demoulding. The present invention can use polystyrene particles obtained by crushing discarded polystyrene boards as thermal insulation fillers, and use crop straw It is a fiber reinforced material with a wide range of raw materials and low cost, energy saving and environmental protection, and realizes waste recycling. At the same time, the wallboard can be made by the foundry, with fast forming, extremely short installation cycle, long service life, heat insulation and sound insulation, and is not afraid of water. ; but this preparation process still has certain shortcomings: the crack resistance of the lightweight wallboard made by this preparation process is low, and cracks are easy to occur; the lightweight wallboard often leaks during use, especially in rainy weather phenomenon, which seriously affects and restricts the application of lightweight wall panels, especially not suitable for prefabricated buildings
