Abstract
The invention discloses a kind of novel heat-insulation coating being applicable to anti-shearing high-temperature resistant water polyurethane composite thermal insulation pipe, it is characterized in that it is made up of the raw material of following weight part: acrylic resin 30-35%, butyl acrylate 6-8%, dehydrated silicate 3-5%, whipping agent 5-7%, defoamer 3-5%, silicon metal 28-32%, titanium dioxide 6-8%, zirconium white 0.8-1.2%, Wingdale 5-7%, antiseptic-germicide 2-4%.The present invention not only has high-temperature resistant result, can also improve bonding force, and ensure " trinity " effect of pipeline, the insulation particle of hollow can play the effect of cooling.During delivery medium 140 DEG C, make the temperature of urethane and thermofin contact surface drop to less than 120 DEG C by the cooling-down effect of thermofin, urethane is used at the temperature of a safety.
Description
Technical field
The invention belongs to a kind of thermal insulating coating, specifically a kind of thermal insulating coating being applicable to insulating pipe.
Background technology
At present, China's city direct-burried heat supply utilidor is generally high density polyvinyl polyurethane prefabricated direct-buried thermal insulation pipe, and in power plant's practical application, hot water heat insulating pipe is most is ultrahigh-temperature use, and temperature is generally all between 130-150 DEG C.But urethane is applicable to be no more than delivery medium in 120 DEG C of situations, because just there will be carbonization phenomenon more than 120 DEG C of long-time running urethane, makes its heat insulation effect decline, pipeline reduction in work-ing life.Therefore, utilidor requires just more and more higher to the coating of steel tube surface layer, both required that coating was high temperature resistant, and required that again coating had stronger effect of heat insulation.And current existing coating heat-resisting ability is poor, most high-temperature resistant can only reach 120 DEG C, and sticking power is strong, can not meet the requirement of conveying high-temperature medium, and work-ing life is shorter.
Summary of the invention
The object of the present invention, be to overcome the above-mentioned deficiency of prior art, a kind of thermal insulating coating being applicable to anti-shearing high-temperature resistant water polyurethane composite thermal insulation pipe is provided, it is high temperature resistant and heat-proof quality is strong, urethane can be met use at the temperature of a safety, and there is stronger sticking power, improve heat insulation effect, increase the service life.
For reaching above-mentioned object, the present invention takes following technical scheme: the present invention is made up of the raw material of following weight part: acrylic resin 30-35%, butyl acrylate 6-8%, dehydrated silicate 3-5%, whipping agent 5-7%, defoamer 3-5%, silicon metal 28-32%, titanium dioxide 6-8%, zirconium white 0.8-1.2%, Wingdale 5-7%, antiseptic-germicide 2-4%.
Acrylic resin is a kind of crystalline polymer of compound with regular structure, and resistance toheat is good, and its fusing point is about 170 DEG C, without under External Force Acting, 150 DEG C indeformable, and chemical stability is good, acid-and base-resisting and organic solvent, do not have an effect with most of pharmaceutical chemicals, and absorb water hardly.
Third butylacetate is used as organic synthesis intermediate, tackiness agent, emulsifying agent, coating, in use, often by acrylic ester polymers synthetic polymer or multipolymer.
Dehydrated silicate fusing point is high, stable chemical nature, has the features such as unit weight is light, intensity is high, thermal conductivity is little, high temperature resistant, corrosion-resistant, is applied to heat insulating.
Whipping agent is exactly the material making object material pore-forming, and it can be divided into chemical foaming agent and pneumatogen and tensio-active agent three major types.Whipping agent all has higher surfactivity, effectively can reduce the surface tension of liquid, and surrounds air in the electric double layer arrangement of liquid film surface, forms bubble, then forms foam by single isolated bubbles.
Defoamer, be also called kilfoam, many unwanted bubbles can be produced in industrial process, need to add defoamer, be widely used in removing the unwanted bubbles produced in the industry production processes such as latex, textile sizing, food fermentation, biological medicine, coating, petrochemical complex, papermaking, industry cleaning link.
Silicon metal, zirconium white, Wingdale all have high, the resistant to elevated temperatures feature of fusing point, suitable heat-insulation and heat-preservation.
Titanium dioxide is applicable to pigment, is white.
Antiseptic-germicide has antibacterial and bactericidal property.
The present invention takes technique scheme, has following beneficial effect: the present invention applies thermal insulation layer polyurethane high temperature resistant thermal insulating coating, and coating state is white slurry, evenly without lump after stirring, under 25 ± 1 DEG C of environment, surface drying time is 1 hours, and the time of doing solid work is 12 hours; Sticking power can reach 1 grade, heat resistance is high, in 170 ± 5 DEG C of situations of being heated, coating can be intact, be applicable to the production of Novel high-temperature-resistant heat insulation pipe, meet the indices required by product performance, prevent the practical problems of polyurethane insulation coating Yin Gaowen and carbonization, solve the difficult problem that life-time service temperature more than 120 DEG C high-temperature-resistant thermal-insulation pipes are produced.The present invention not only has high-temperature resistant result, can also improve bonding force, and ensure " trinity " effect of pipeline, the insulation particle of hollow can play the effect of cooling.During delivery medium 140 DEG C, make the temperature of urethane and thermofin contact surface drop to less than 120 DEG C by the cooling-down effect of thermofin, urethane is used at the temperature of a safety.
