The present invention is that a kind of cement with certain proportional quantity is tackiness agent, pearlstone is a light skeletal, add admixtures such as water reducer, accelerating chemicals, air entrapment agent again, make the making method of pearlite foam article by expasion of cement through stirring foaming, natural flowing forming, maintenance.This method technology is simple, and the goods finished product is low, proportion is little, matter is soft, be easy to lacquer and surface treatment, can make top ceiling, acoustic board, indoor wall plate and decorative sheet etc., and can satisfy the requirement of interior decoration.
Description
The present invention relates to a kind of making method of insulating, porous shaping product, particularly a kind of is jointing compound with cement, and pearlstone is a light skeletal, and adds the making method of the pearlite foam article by expasion of cement that admixture is arranged.
Perlite is a kind of tart glassiness volcano extrusive rock.After perlite pulverizing, preheating, roasting rapidly in high temperature (about 1250 ℃), the violent expansion of volume can be made into a kind of light porous granulous pearlstone.Expanded perlite product has many types, wherein be jointing compound with cement, pearlstone is an aggregate, cooperates by certain proportioning, stirring, screening, compression moulding, maintenance and the cement expanded perlite goods made, have advantages such as insulation, heat insulation, sound absorption, but porosity is little, than great, hardness is big, be difficult for perforating, and need compression moulding, cost height.
The objective of the invention is to overcome weak point of the prior art, a kind of both lightweights are provided, matter is soft, is easy to lacquer and surface treatment, and production technique is simple again simultaneously, the making method of the pearlite foam article by expasion of cement that cost is low.
Purpose of the present invention can reach by following measure:
A kind of making method of pearlite foam article by expasion of cement, after adding the cement and pearlstone of certain proportional quantity, adding is with the water reducer of water dissolution or dilution, accelerating chemicals, in the admixtures such as air entrapment agent two kinds or several, the specific gravity control that stirring foams again makes formation flows into moulding or directly spraying in the shaping mould naturally at the cement expanded perlite foam slurry of 0.5--1.5 (claiming to measure with proportion) scope, be put on metope, on the ceiling, cement, the add-on (representing with the weight % that accounts for these three kinds of total add-ons of composition) of pearlstone and admixture (without the admixture of dissolving or dilution, as follows) is:
Cement 60-94
Pearlstone 3-30
Admixture 0.3-15
Water cement ratio in the batching (being the per-cent of water and cement, pearlstone, admixture three gross weight, as follows) is 0.30-0.80.
Water reducer that the present invention adds can reduce the water consumption of given this foam slurry under the condition that does not influence cement expanded perlite foam slurry flowability; Also can under the condition that does not change water consumption, increase the flowability of foam slurry; When keeping identical flowability of foam slurry and hardened foam slurries that close intensity is arranged, also can reduce cement consumption behind the adding water reducer.
Accelerating chemicals that the present invention adds can be accelerated cement expanded perlite foam slurry initial stage and final rate of set, thereby reaches the purpose of the rate of growth that increases the foam slurry early strength.
Air entrapment agent that the present invention adds is that a kind of can make in the foam slurry produces the admixture that can keep microbubble after tiny, uniform distribution and the sclerosis.
The present invention adds water reducer and accelerating chemicals after utilizing adding cement and pearlstone, just can produce a large amount of foam (also not adding air entrapment agent this moment) by stirring, after adding air entrapment agent again, surfactivity effect and light skeletal pearlstone by air entrapment agent itself have the characteristic of light porous energy introducing air, with cement as tackiness agent, pearlstone is as the loss of weight agent, chemical agent as air entrapment agent etc. with add a certain amount of water, in the stirrer whipping process, can form more, more even, the more stable many foam slurries of a kind of foam.The proportion of foam slurry can be adjusted by the dosage that changes pearlstone as required.The present invention utilizes the proportion of this many foam slurries of control to regulate indexs such as the ideal unit weight of pearlite foam article by expasion of cement, resistance to compression, anti-folding, is made into products such as pearlite foam article by expasion of cement such as top ceiling, acoustic board, indoor wall plate and decorative sheet.The present invention also can flow into the cement expanded perlite foam slurry and complete in filamentary material or the forming mould wiry, make pearlite foam article by expasion of cement through moulding, maintenance, lacquerization and surface treatment again, also can also can receive purposes such as insulation, sound absorption, sound insulation foam slurry directly being sprayed or is put on lacquer and surface treatment after the curing on metope, the ceiling.
Purpose of the present invention can also reach by following measure:
A kind of making method of foregoing pearlite foam article by expasion of cement, institute adds admixture and can be following any type and consumption (weight %):
(1), the accelerating chemicals of the water reducer of 0.1--3.0 and 0.5--10.0;
(2) accelerating chemicals of the water reducer of .0.1--3.0 and 0.5--10.0 and 1 * 10
-4---1.0000 air entrapment agent.
The churning time that adds admixture is preferably 10-40 minute.
Water reducer of the present invention can be a kind of in this quality water reducer, sulfonated coal tar water reducer, the resin water reducer etc. or several.
Accelerating chemicals of the present invention can be a kind of in the following accelerating chemicals or several:
Inorganic setting accelerator such as sodium-chlor, calcium chloride, sodium sulfate, Sulfothiorine etc.;
Organic accelerating chemicals such as trolamine, tri-isopropanolamine, methyl alcohol, ethanol, sodium acetate, calcium formiate, lithium oxalate, urea etc.;
Organic and inorganic compound accelerating chemicals is as pressing trolamine: add after the mixed of sodium-chlor=1: 10 in 1% the sodium nitrite solution.
Air entrapment agent of the present invention can be a kind of in rosin and thermopolymer class, nonionic surface active agent class, lignosulfonic acid salt, alkyl benzene sulfonate etc. or several.
The present invention has following advantage compared to existing technology:
1, do not need press compression moulding, and flow into the shaping mould curing molding by nature, thereby manufacture craft is simple, cost is low, and cement expanded perlite plate price is 130-200 unit/rice
3, and the plate price that the present invention makes is 80-160 unit/rice
