Abstract
The composite insulating paste appearing as enclosed microporous fibre-net structure after drying is produced through immersing asbestos and penetrating agent in water, beating for 10-30 min, mixing the pulp with expanded pearlite and waste polystyrene foam particles, defoaming for 24 hr in tank, and bagging. It is suitable for pipeline, tank body, freezing apparatus and building at less than 100 deg.C.
Description
The present invention relates to a kind of compound insulating paste and production method thereof, belong to the thermal isolation technique field, be applicable to the heat-insulation and heat-preservation of various pipelines, tank body, equipment or buildings.
Existing lotion lagging material such as CN87102864A open the compound heat-insulating silicate material and the production method thereof of cloth, adopt serpentine, asbestos to do aggregate, mountain cork, alumina-silicate ceramic fibre, pearlstone, diatomite, wilkinite is made filler, make permeate agent with promoting agent, with polyvinyl alcohol water solution, water glass, phosphoric acid aluminium liquid are made the tackiness agent composite copolymerization.Making method is to adopt high-temperature water to soak and electrostatic technique.Its shortcoming is that the asbestos consumption is big, the drying shrinkage height, and dry body density is big, and heat-insulating property is not ideal enough.
The objective of the invention is to overcome above-mentioned weak point of the prior art, and provide a kind of asbestos consumption few, dry density is little, and thermal conductivity is low, and drying shrinkage is little, and cost is low, simple compound insulating paste of making method and production method thereof.
The object of the present invention is achieved like this: the form of this compound insulating paste is a paste composition, dry rear enclosed microporous mesh fibrous texture layer, its composition and ratio are (weight ratio): asbestos 8～15%, pearlstone 15～20%, waste polystyrene foam plastic particle 15～20% floats pearl 15～20%, wilkinite 10～18%, permeate agent 3～8%, tackiness agent 4～7%.Production method is to get asbestos earlier by proportioning, add in the normal-temperature water of 10 times of suitable asbestos weight, add permeate agent, soaked 24 hours, with 1000 rev/mins hollander making beating 10～30 minutes, again with remaining pearlstone, waste polystyrene foam plastic particle, float pearl, wilkinite and tackiness agent compound and be added in the asbestos slurry of accomplishing fluently slurry, with 300 rev/mins stirrer stirring 5～10 minutes, static froth breaking was finished product in 10～24 hours again.Wherein the waste old polystyrene foamed plastic particle is utilization of waste material, and plays and reduce thermal conductivity and density, strengthens the effect of heat-insulating property.
Purpose of the present invention can also reach by following measure:
The best proportioning (weight ratio) of its component content is: asbestos 15%, and pearlstone 20%, waste polystyrene foam plastic particle 20% floats pearl 20%, wilkinite 15%, permeate agent 4%, tackiness agent 6%.Permeate agent is a sulfonation amber acid dibutyl ester, and tackiness agent is 107 glue.
The present invention compares with background technology has following effect and advantage:
1, the waste old polystyrene foamed plastic particle is utilization of waste material, can reduce the pollution to environment.
2, good heat insulating, thermal conductivity is≤0.035W/mk.
3, body is light, dry density≤150kg/m
3
4, cost is low, can hang down more than 20% than existing slurry heat-insulation material.
5, the slurry fast drying after the construction shortens more than 30% than existing slurry heat-insulation material time of drying.
The invention will be further described below in conjunction with (accompanying drawing) embodiment:
Accompanying drawing is a process flow sheet of the present invention.
Embodiment: get 15 kilograms in asbestos, 4 kilograms of permeate agents are put into 150 kilograms normal-temperature water, soak 24 hours, pull an oar 10 minutes with the hollander that per minute 1000 changes.Again with 20 kilograms of the pearlstones of impurity elimination, 20 kilograms of waste polystyrene foam plastic particles, float 20 kilograms on pearl, 15 kilograms of wilkinites, 107 glue are dosed for 6 kilograms in the asbestos slurry of accomplishing fluently slurry, the stirrer that changes with per minute 300 stirred 10 minutes again, and static froth breaking is 24 hours in material storage container, can pack standby.
