Abstract
Manufacturing process of light construction material of fine grain expanded pearlite, gather materials with the fine grain expanded pearlite conduct, adopt new burl agent prescription, through waterglass spray and impregnation process, product strength height, the cost made are low, and have sound insulation, heat insulation, fire resistance, have overcome to be bonded into the low shortcoming of intensity that light material exists with fine grain expanded pearlite in the prior art, can be widely used in construction material, also can be used for industries such as chemical industry, light industry.
Description
The present invention relates to a kind of manufacturing process that adopts fine grain expanded pearlite to make light-weight building material.
At present, the fine grain expanded pearlite goods are generally made insulation or sound-absorbing material, perhaps as decorative panel.As insulation material is to be adhesive with portland cement, pressurizes after the moulding, steam curing forms.As abatvoix is to make adhesive with waterglass, polyvinyl alcohol, and 180-200 ℃ of oven dry formed in 2 hours after the extrusion forming, and the intensity of these goods is 3-8
KG/Cm
2, can't be widely used as construction material.
The purpose of this invention is to provide a kind of new manufacturing process, as gathering materials, adopt new caking agent formula with fine grain expanded pearlite, make have higher-strength, cost is low, and energy sound insulation, heat insulation, water-fast, fire-resistant light-weight building material.
The present invention by following by way of realization: fine grain expanded pearlite, water and bonding agent are mixed, craft or extrusion forming, spray or impregnation process with waterglass then, air dry at normal temperatures or heating, drying at last, light-weight building material, more than the bonding agent of Cai Yonging can be any one or a few the mixture in natural zeolite, gypsum, lime, these four kinds of materials of portland cement.The weight percent of fine grain expanded pearlite and binding agent consists of:
Fine grain expanded pearlite: 25-97%
Binding agent: 3-75%
Realize that second scheme of the present invention is that natural zeolite, fine grain expanded pearlite, waterglass are mixed the back extrusion forming, then 180-220 ℃ of oven dry down, and be incubated 0.5-3 hour.Wherein, the weight percent of three kinds of materials consists of:
Natural zeolite: 10-60%
Fine grain expanded pearlite: 20-50%
Waterglass: 20-70%
The light-weight building material that adopts the present invention's first scheme and make, unit weight 250-900
KG/m
3, compression strength is 5-50
KG/Cm
2
The light-weight building material that adopts alternative plan of the present invention and make, unit weight is 200-900
KG/m
3, compression strength is 5-30
KG/Cm
2
Adopt manufacturing process of the present invention, can obtain the compression strength height, low and the light-weight building material of cost with fire-resistant, water-fast, sound insulation, heat-proof quality, the goods made from this technology also can be used for industries such as chemical industry, light industry.
Embodiments of the invention 1: adopt 30-80%(weight) natural zeolite, 10-50%(weight) lime, 5-40%(weight) gypsum, 5-50% portland cement mix mutually, as bonding agent.Get 100 parts of this bonding agents (weight), stir after adding fine grain expanded pearlite 50-300 part (weight) mixing, craft or extrusion forming then is again with waterglass spray or impregnation process, take out back air dry or 60-220 ℃ of oven dry, just can obtain compression strength is 5-50
KG/Cm
2, unit weight 250-900

3Goods.
Embodiment 2: use 50-95%(weight) natural zeolite, adding 5-50%(weight) lime or gypsum (or lime adds gypsum) are made bonding agent, get 100 parts of (weight) these bonding agents, adding fine grain expanded pearlite 50-300 part (weight) mixes, craft or extrusion forming then, through waterglass spray or dipping, take out air dry or 60-220 ℃ of oven dry again, promptly getting compression strength is 5-50
KG/Cm
2, unit weight is 250-900
KG/m
3Goods.
Embodiment 3: adopt lime or gypsum (or lime adds gypsum) as bonding agent, get 10-50%(weight) this bonding agent, adding 50-90%(weight) the fine grain expanded pearlite mixing is mixed thoroughly, craft or extrusion forming then, through waterglass spray or impregnation process, take out air dry or 60-220 ℃ of oven dry, promptly getting compression strength is 5-50
KG/Cm
2, unit weight 250-900
KG/m
3Goods.
Embodiment 4: natural zeolite 10-60%(weight), fine grain expanded pearlite 20-50%(weight), waterglass 20-70%(weight) three mixes stirring, extrusion forming, 180-220 ℃ of oven dry then is incubated 0.5-3 hour, promptly gets compression strength 5-30
KG/Cm
2, unit weight 200-900
