CN1124750A - Non-toxic compounded insulation paint - Google Patents

Abstract

The non-toxic compound insulating paint is made of flyash from power plant, sepiolite, pearlite, ceramic fibre, penetrant, bentonite, water glass, polyvinyl alcohol, adhesive "831", lime and gypsum, features no poison, no pollution and low thermal conductivity.

Description

Non-toxic compounded insulation paint

The invention belongs to a kind of non-toxic compounded insulation paint.

In present technology, the general coated materials that adopt are incubated pipeline more.Exist the coated inconvenience of special-shaped pipeline in this way, the inconvenient problem of coated material transportation.All contain the toxic materials asbestos in addition in the coated material.

The purpose of this invention is to provide a kind of non-toxic compounded insulation paint, be used for the pipeline or the planar coating of various needs insulations.

The objective of the invention is to be realized by following proposal: it comprises power plant's dust, sepiolite, perlite, ceramic fiber, permeate agent, wilkinite, water glass, polyvinyl alcohol, tackiness agent 831, lime and gypsum, and its weight percent is:

Power plant's dust: 5～10%;

Sepiolite: 8～12%;

Perlite: 3～6%;

Ceramic fiber: 1～5%;

Permeate agent: 0.5～1.5%;

Peng Run soil: 0.1～1%;

Water glass: 0.1～1%;

Polyvinyl alcohol: 2～6%;

Tackiness agent 831:0.2～0.8%;

Lime: 0.3～1%;

Gypsum: 1～5%;

Water: 65～75%.

That the present invention has is nontoxic, pollution-free, thermal conductivity is low, applied thickness is thin, heat-proof quality is good, energy-saving effect is remarkable, the advantage of corrosion-resistant, easy construction.Coated owing to need not to tie up, so the various special-shaped equipment that are difficult to be incubated are more had unique advantage.

Embodiment:

Optimum weight proportioning of the present invention is:

Power plant's dust: 6%;

Sepiolite: 8.5%;

Perlite: 4%;

Ceramic fiber: 1.3%;

Permeate agent: 0.98%;

Wilkinite: 0.5%;

Water glass: 0.58%;

Polyvinyl alcohol: 3.3%;

Tackiness agent 831:0.3%;

Lime: 0.6%;

Gypsum: 2.1%;

Water: 72%.

Blending process is as follows:

Earlier with ceramic fiber with water logging and, put into agitation vat then, add permeate agent again, add sepiolite, wilkinite, power plant's dust, perlite successively, continue to add water and stir, in whipping process, splash into polyvinyl alcohol, water glass and tackiness agent 831.Be stirred to proper time, the check pH value reaches 6～8 and gets final product.The present invention's this moment becomes slurry, and slurry is put into the froth breaking pond, can pack after 24 hours and dispatch from the factory.The nontoxic composite coating of making now belongs to heat curing-type, and it directly is applied to pipeline or the plane of in situ temperature more than 80 degree.Be coated with pipeline or plane temperature when 80 degree are following, needed at the construction field (site), added lime and gypsum again.The even back of mixing is the speed construction.

The present invention can be widely used in insulation, thermal insulation, sound insulation and the fire prevention of pipeline, gate, stove, tank body, spheroid, rotator, metope of industrial sectors such as oil, chemical industry, electric power, metallurgy, papermaking, sugaring, light textile, building, medicine, glass, pottery and national defence etc.
