Abstract
The invention discloses a pressure-resistant heat insulation material containing pitchstone. The pressure-resistant heat insulation material is prepared from the following ingredients in parts by weight: 36 to 40 parts of 200 mesh-300 mesh pitchstone powder, 19 to 24 parts of hydroxy propyl cellulose, 16 to 18 parts of lignocellulose, 22 to 25 parts of dilute methylsilicone oil, 9 to 18 parts of phenolic resin, 17 to 22 parts of trimeric sodium phosphate, 5 to 7 parts of magnesium bicarbonate and 29 to 33 parts of water. The prepared heat insulation material containing pitchstone has the advantages that the pressure-resistant capability and the heat insulation effect are good; the pressure-resistant intensity is 9 to 13Mpa; the heat conduction coefficient is 0.026 to 0.029W/(m.K). The heat insulation material can be used as a curtain wall heat insulation material.
Description
Technical field
The present invention relates to a kind of lagging material, particularly relate to a kind of resistance to compression lagging material containing pitchstone.
Background technology
In office building exterior wall, and when house carries out isothermal holding, need to use lagging material.The heat insulation effect of selection to buildings of lagging material has very tremendous influence.If lagging material heat insulation effect is poor, then the thermal conductivity of lagging material is too low, and then the environment that result in heat and the external world exchanges fast, not save energy.The ultimate compression strength of lagging material has very large effect to the use of lagging material equally, and we need to find the lagging material not only with good heat preservation effect, also should have higher ultimate compression strength.
Summary of the invention
The technical problem to be solved in the present invention: the common problem that lagging material heat insulation effect is poor, ultimate compression strength is lower.
Technical scheme: the invention discloses a kind of resistance to compression lagging material containing pitchstone, material is made up of according to weight ratio following composition: 200 order ~ 300 object rosin rock dust are 36 ~ 40 parts, hydroxypropylcellulose is 19 ~ 24 parts, lignocellulose is 16 ~ 18 parts, western methyl-silicone oil is 22 ~ 25 parts, resol is 9 ~ 18 parts, tripoly phosphate sodium STPP is 17 ~ 22 parts, Magnesium hydrogen carbonate is 5 ~ 7 parts, water is 29 ~ 33 parts.
Resistance to compression lagging material preparation flow containing pitchstone is as follows: first get the various materials prepared needed for material, 200 order ~ 300 object rosin rock dust are 36 ~ 40kg, hydroxypropylcellulose is 19 ~ 24kg, lignocellulose is 16 ~ 18kg, western methyl-silicone oil is 22 ~ 25kg, resol is 9 ~ 18kg, tripoly phosphate sodium STPP is 17 ~ 22kg, Magnesium hydrogen carbonate is 5 ~ 7kg, water is 29 ~ 33kg, stir under above-mentioned each composition room temperature in stirred pot, put into mould after stirring, toast 3h at 80 DEG C after, obtain the resistance to compression lagging material containing pitchstone.
Beneficial effect: the lagging material containing pitchstone prepared has good anti-pressure ability and heat insulation effect, and ultimate compression strength is 9 ~ 13Mpa, and thermal conductivity is 0.026 ~ 0.029W/ (mK).Can as the lagging material of curtain wall.
