Abstract

The water-proof, heat-insulating composite material is prepared with refractory rare-earth adhesive (0.001-0.002%), diatomite (1-10), rare-earth water-proofing agent (1-1.5), composite rare-earth additive (1-6), modified pearlite (1-5), aluminium silicate fibre (6-12), calcium lime (8-12) and water through thoroughly mixing to become cream, which may be directly coated on surface of equipment or made into coiled material for wrapping the surface of equipment.

Description

Full-water-proof composite thermal-insulating material

The invention belongs to a kind of lagging material that has water-proof function concurrently.Heat-insulation and heat-preservation material with prescription provided by the invention and explained hereafter integrates insulation, heat insulation, waterproof, and variform and specifications such as slurry, coiled material, section bar are arranged, be widely used in the various device of industries such as chemical industry, metallurgy, weaving, medicine, building, traffic, oil, national defence, electric power or the heat-insulation and heat-preservation of buildings, be specially adapted to the special-shaped equipment of indoor and outdoor that traditional lagging material is difficult to be competent at, as the heat-insulation and heat-preservation of rotary spherical digester, gate valve, special-shaped equipment etc.

The various heat insulating coatings of Chu Xianing compare with traditional lagging material in recent years, have easy construction, advantage applied widely, and particularly in the heat insulating work of special-shaped equipment, its advantage is more obvious.But this class coating all must add at its skin and is coated with water-resisting agent, and both having improved construction costs has also influenced construction speed.

The present invention aims to provide a kind of material that has heat insulating and water-proof function concurrently, thermal insulation layer and waterproof layer are united two into one, become twice construction into once construction, three major types plurality of specifications such as slurry, section bar, coiled material are arranged because of it again, be convenient to the user and select as the case may be to use.Usually, slurry is suitable for the heat insulating work of special-shaped pipeline, equipment etc., and it is even to have an insulation layer thickness, does not need to wrap up the advantage that twines, but dry slow; Section bar, coiled material are applicable to the heat insulating work of long straight pipeline or regular shape equipment, and having once shaped need not the exsiccant advantage, but need bonding or twine, and be relatively poor to the adaptability of special-shaped pipeline and equipment.

This invention is a raw material with high-temp glue, diatomite, full water-resisting agent, compound rare-earth additive, modification perlite, aluminum silicate fiber, unslaked lime and water, and it is implemented to fill a prescription and is:

Material rate (weight ratio) material rate

High-temp glue 0.001% full water-resisting agent 6%

Diatomite 6% compound rare-earth additive 5.999%

Unslaked lime 10% modification perlite 5%

Water 62% aluminum silicate fiber 10%

Be summarized as follows below in conjunction with the production process of process flow sheet this material:

With diatomite, modification perlite, aluminum silicate fiber, four kinds of raw materials of unslaked lime, through select materials, after the removal of impurities, pulverizing, metering according to the above ratio and rare earth high-temp glue, full water-resisting agent, the disposable agitated pool that drops into simultaneously of compound rare-earth additive add water and mix and stir.Can evenly be applied in equipment or building surface after waiting to stir into even lotion, also this slurry can be pressed into section bar or coiled material with shaper, dry stand-by, this moment water ratio should suitably reduce.

With the lagging material that the present invention produces, its every performance has has all met or exceeded national standard, and maximum operation (service) temperature reaches 1250 ℃, and the specific performance index is as follows:

1, slurry density 〉=830kg/m ³5, thermal conductivity＜0.06w/m.k(350 ℃)

2, dry density＜180kg/m ³6, oil-proofness machine oil, the 24h no change

3, hydrophobic degree 100% 7, acid resistance 30%HCL, the 24h no change

4, cohesive force＞4000N/m 8, alkali resistance 40%NaOH, the 24h no change

With prescription of the present invention and explained hereafter thermal insulation coatings, equipment used is few, technology is simple, raw material need not chemical treatment, but its core composition rare earth high-temp glue, the full water-resisting agent of rare earth, rare earth composite additive all centralized production, dispersion use, reduce the input and the business risk of the fund of the producer of generally practicing midwifery, had good social benefit and economic benefit.This product heat-proof quality is good, and cohesive force is strong, good waterproof performance, and the Applicable temperature zone is wide, and cost is low, easy construction, surfacing is attractive in appearance, is the optimal selection of every profession and trade heat insulating work.
