Description
Affiliated technology neck
The invention belongs to engineering decontamination technology field, what relate generally to is a kind of response type inhabitation detergent.
Background technology
Be accompanied by the development and the widespread use of nuclear energy technology, nuclear and radiation radioactive contamination decontamination problem have also obtained paying close attention to widely.Exfoliated film body compacting decontamination technology as a kind of for compacting, radioaerosol and ground radioactive fallout are desirable technological means in the removing air, development in recent years is rapid, and in the application of having arrived widely in nuclear and radiation radioactive contamination large tracts of land engineering decontamination technology field, its representative material is SMDW series exfoliated pressed detergent and the FSM04 inhabitation detergent that Headquarters of the General Staff engineer scientific research three is researched and developed, these inhabitation detergent products are at soil removal efficiency, application, with aspect such as existing weaponry and equipment suitability its special advantages is arranged, remove in civilian nuclear facilities accident radioactivity consequence compacting and having obtained widespread use.Yet these products are applied to field such as opening up of emergent road under China strategy nuclear arsenal accident, strategic nuclear weapons test incident, city terror " dirty bomb " radioactivity consequence elimination aspect and nuclear war, the accurate coring war condition and use and still have its bigger defective and deficiency.Use in these fields, material allows personnel, equipment to pass through within a short period of time after requiring compacting decontamination operation, environmental baseline when current will reach environmental radiation standard in wartime basically, the setting time of these inhabitation detergents, film body splitting time are longer relatively, do not reach ageing requirement in wartime.In addition, existing these inhabitation detergents all belong to water capacity material, it solidifies is the volatilization that mainly relies on moisture in the material, because the evaporation rate of water is subjected to the influence of environment temperature, humidity very big, this also badly influences the use of these materials in northern low temp area of China and southern humid area environment.Therefore,, need to develop new material, adapt to the fast quick-recovery of environment in wartime, the request for utilization in China's low temp area, humid environment area for remedying existing inhabitation detergent aspect the timeliness and the defective of environment for use aspect.
Existing inhabitation detergent has limited the widespread use of existing compacting decontamination material in large tracts of land nuclear emergency engineering decontamination field aspect timeliness and the defective of environment for use and deficiency greatly.
The purpose of invention
Task of the present invention promptly is the deficiency that exists for existing inhabitation detergent, and it is rapid to propose a kind of curing, and the novel reaction type inhabitation detergent that can use in low temperature and wet environment.This detergent is a bi-component reaction-type, and wherein the first component is polyether glycol, chain extender, catalyzer and various agent mixture, and the second component is an isocyanates.Owing in prescription, added chain extender, can effectively improve the chain link of polyether glycol and isocyanate polymer, the gained product form and can form certain thickness film body and have certain compliance, and breaking elongation is improved, and can be used for inhabitation detergent.Owing to the set time that the adding of catalyzer has effectively improved polyether glycol and isocyanate polymer, reduced the time that forms film body.Be applied to engineering decontamination technology field, have compacting and decontamination double effects, set time is fast, and the film body of formation satisfies the requirement that mechanization is reclaimed, and has certain water resisting property, is adapted at the practicality of humidity larger area.
The technical scheme that the present invention provides is: this response type inhabitation detergent is a bi-component reaction-type, wherein comprise polyether glycol, chain extender, catalyzer, solvent, plastifier in the first component, the second component is an isocyanates, is characterized in that the component and the parts by weight of this response type compacting inhabitation detergent are:
Polyether glycol 760
Chain extender 122
Catalyzer 0.6
Isocyanates 114
Preferred ingredients and parts by weight are:
Polyether glycol 750～800
Chain extender 115-130
Catalyzer 0.5～0.7
Isocyanates 120～130
Said polyether glycol comprises that common polyethers, DMC polyethers and Acclaim polyethers polyether glycol are the polyfunctionality polyethers of relative molecular weight between 2000～4000 among the present invention.
Said chain extender is materials such as glycerine and MOCA among the present invention.
Said catalyzer comprises stannous octoate and dibutyl tin laurate among the present invention.
Said solvent is for comprising toluene and acetone among the present invention.
Said plastifier is a dioctyl phthalate among the present invention.
The said isocyanates of the present invention is diisocyanates such as toluene diisocyanate, methyl diphenylene diisocyanate, naphthalene diisocyanate.
The various industrial chemicals of being mentioned in the above technical scheme all can be buied from the home market.
The preparation technology of first component is among the present invention: stir and can make mixing with catalyzer, solvent, plastifier by described proportioning at normal temperatures behind polyether glycol, the chain extender high temperature dehydration.
Compared with prior art, the present invention has following characteristics:
(1) detergency ability is good, and the soil removal efficiency on various basal planes can reach more than 95%;
(2) setting time is fast, after ground spraying, can satisfy weight equipment by asking in 2 hours.
(3) have certain water resistance, in water, invade bubble for a long time after the film forming after, every performance of film body does not have marked change;
(4) applicability is strong, is suitable for the decontamination operation of various dielectric surfaces.
