Abstract
The invention relates to an insulating coating for an electrical heating pipe of an electric water heater. The insulating coating is composed of a polyester imide resin, silicone rubber, mineral wool insulation fibers, silicon nitride, alumina, titanium dioxide and a solvent. The insulating coating provided by the invention has outstanding overall performance such as heat resistance; a thermal conductivity is 0.03 W/m.K; thermal insulation inhibition efficiency can reach about 90%; and thermal radiation and heat dissipation of a high temperature object and a low temperature object can be inhibited. Experiments show that when being used at a temperature of 250 DEG C +/-20 DEG C, the insulating coating composition does not crack or fall for 300 h, and has high flexural strength as high as 10 MPa.
Description
Technical field
The present invention relates to a kind of insulation compound, particularly a kind of electric water heater electric heating tube insulation compound, belong to the technical field of electric heater unit.
Background technology
Electric water heater is usingd the water-heater that electricity heated as the energy and is commonly referred to electric water heater.The power of electric water heater is generally 900～7500W.Heating tube is the key part of electric water heater.Electric heating tube is to take metal tube as shell, along central shaft in pipe, to its space padding and compacting of distributing auger lectrothermal alloy wire (nickel chromium triangle, ferrochrome exothermic), has the magnesium oxide sand of good insulation heat conductivility, silica gel or ceramic seal for mouth of pipe two ends.
Heating tube of the prior art, comprise housing, heater strip, described space padding and compacting has the magnesium oxide sand of good insulation heat conductivility, in order to improve the insulating property of heating tube, usually be provided with insulating coating outside housing, traditional insulating coating intensity does not reach requirement, and the housing of heating tube slightly has distortion, insulating coating just there will be crackle, reduce the insulativity of heating tube, thereby, greatly reduce the security of electric heating tube.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of good insulation preformance, heat-transfer rate electric water heater electric heating tube insulation compound fast and simple in structure, this electric water heater electric heating tube insulation compound good insulation preformance, thereby, greatly improved the overall security of electric water heater.
In order to solve the problems of the technologies described above, a kind of electric water heater electric heating tube of the present invention insulation compound, described insulation compound consists of the following composition, by weight meter:
Polyester imine resin 80-90 part
Silicon rubber 50-60 part
Rock wool 20-30 part
Silicon nitride 10-15 part
Aluminum oxide 10-15 part
Titanium dioxide 8-15 part
Solvent 10-12 part.
Above-mentioned electric water heater electric heating tube insulation compound, wherein, solvent is comprised of toluene acetic acid, methyl esters and trieline, toluene: ritalin: trieline is 5:3:1, by weight.
Above-mentioned electric water heater electric heating tube insulation compound, wherein, described insulating coating screening formulation is as follows, by weight meter:
