Embodiment 1

[0013] Put water, sodium rosinate, water-soluble polyvinyl alcohol powder, naphthalene-based water reducer, calcium stearate, 12 mm long chopped polypropylene fiber, fly ash, and 42.5# ordinary Portland cement into the mixing tank in sequence, Stir at high speed with a high-speed dispersing mixer to make foamed cement slurry; pump the foamed cement slurry to the ribbon mixer, and put in recycled particles of waste polystyrene foam while stirring; pour the mixed material into the combination In the mold, flatten it; after it solidifies, take out the fastening square tube, unlock the lock, take off the four side panels, and then take out the insulation board and partition in turn; clean the mold, apply the release agent, and reassemble it for later use; The demoulded insulation boards can be stacked in the curing area for curing.

[0014] Embodiment 1 The weight ratio of each component of lightweight aggregate foamed cement mixture is as follows:

[0015]

Embodiment 2

[0017] Water, hydrogen peroxide, hydroxypropyl methylcellulose, polycarboxylate superplasticizer, sodium methyl silicate, calcium formate, 6 mm long chopped glass fiber, ceramic sludge, 42.5# low alkalinity sulfoaluminate The cement is put into the mixing tank one by one, stirred at high speed with a high-speed dispersing mixer to make foamed cement slurry; the foamed cement slurry is transported to the ribbon mixer, and the expanded perlite particles are added while stirring; the mixed material is poured Put it into the combination mold and flatten it; after it solidifies, take out the fastening square tube, unlock the lock, take off the four side panels, and then take out the insulation board and partition board in turn; clean the mold, apply the release agent, and reassemble the equipment Use; the demoulded insulation boards can be stacked in the curing area for curing.

Abstract

The invention provides a method for manufacturing a cutting-free lightweight-aggregate foamed cement insulation plate, belongs to the field of building insulation materials, and especially relates tothe lightweight-aggregate foamed cement insulation plate. A combination die is used for replacing traditional raw material dies; the combination die comprises several spaces which are isolated by separator plates, a light-aggregate foamed cement mixture is poured into the combination die, and the mixture is leveled; after the material is solidified, demoulding is carried out in order to obtain multiple insulation plates which are separated by separator plates in the die, and cutting is not needed. The combination die has a simple and practical structure, the lightweight-aggregate foamed cementinsulation plate is produced without raw material cutting equipment, cutting technology does not bring air pollution or water pollution, material loss is reduced, cost is reduced, and efficiency is improved.

Description

technical field [0001] The invention relates to the field of building thermal insulation materials, in particular to lightweight aggregate foamed cement thermal insulation boards. Background technique [0002] Lightweight aggregate foamed cement insulation board has the advantages of fire prevention and heat preservation. The mass production process is generally to pour the lightweight aggregate foamed cement mixture into the block mold, wait for it to solidify, demould, maintain, and then cut according to the specifications. The cutting of the blocks will cause water pollution and air pollution; the sawing will also cause material loss. Contents of the invention [0003] The technical problem mainly solved by the present invention is that there are spaces isolated by several partitions in the composite mold, and the size of the partitions and the distance between the partitions are determined according to the size of the wallboards; the lightweight aggregate foamed cemen...
