Abstract
A production method of heat-insulating material is characterized by that it contains bulked carbohydrate particles and hydrophobic agent whose content is 1-4% of weight of bulked carbohydrate particles, 0.1-0.4% of mildew-proof agent and 0.1-0.4% of anti aging agent, and its production method includes the following steps: bulking the carbohydrate particles under the conditions of 1-4 atm pressure and 150-300 deg.C, and adding hydrophobic agent, mildew-proof agent, anti-aging agent and flame-retarding agent to make modification treatment so as to obtain the invented product with excellent heat-insulating effect, and good hydrophobic property, anti-aging and flame-retarding properties.
Description
What the present invention relates to is a kind of lagging material, the invention still further relates to the making method of this lagging material.
Along with the continuous rise of energy saving building, it is important that the effect of lagging material more and more seems, is that the lagging material of representative is used on market in succession with diatomite, polystyrene foamed, foam cement.Because their aperture is big, void content is low and the thermal conductivity height of material itself, thus their thermal conductivity generally at 0.2-0.4, heat-insulating property is not very good, and these materials are all non-watertight.
The object of the present invention is achieved like this: it contains through the carbohydrate particles of puffing and accounts for through the hydrophober of the carbohydrate particles weight 1-4% of puffing, the mould inhibitor of 0.1-0.4%, the antiaging agent of 0.1-0.4%.
Product of the present invention can also contain: account for the fire retardant through the 0.5-2% of the carbohydrate particles weight of puffing.
Product of the present invention is to be made by following method: with carbon aquation and composition granule under the pressure of 1-4atm, carry out puffing under 150-300 ℃ the temperature and make carbohydrate particles through puffing, adding hydrophober or hydrophober and mould inhibitor, antiaging agent, fire retardant carry out the modification processing in autoclave pressure again, make product, the add-on of described hydrophober, mould inhibitor, antiaging agent, fire retardant accounts for 1-4%, 0.1-0.4%, 0.1-0.4%, the 0.5-2% through the carbohydrate particles weight of puffing respectively.
The decomposition because all carbohydrate of expanded back have dewatered, then decompose part and will stay a large amount of holes, obtained very big volume with minimum quality like this, thereby obtained little and the particle that void content is high in aperture, so the thermal conductivity of product of the present invention is lower, generally be lower than 0.14, have good heat insulation effect.After interpolation hydrophober, mould inhibitor, antiaging agent and fire retardant processing, product of the present invention has good hydrophobic nature, resistance to deterioration, heat-insulation and heat-preservation and flame resistivity.Method of the present invention is simple, realizes easily.
For example the present invention is done more detailed description below:
1, adopt the carbohydrate particles of even matter under the pressure of 1-4atm, carry out puffing under 150-300 ℃ the temperature and make carbohydrate particles through puffing, in autoclave pressure, add the carbon aquation and the hydrophober of composition granule weight 2%, 0.2% mould inhibitor, 0.2% the antiaging agent that account for through puffing again and carry out the modification processing, make product.Hydrophober is one or more in organosilicon macromolecule compound, stearic acid, stearate, the paraffin wax, mould inhibitor can be one or both in s-triazine, the pentachlorophenol, and antiaging agent is that one or more carbon aquations in N-ring ethyl P-nethoxyaniline, styrenated phenol, the organofluorine compound and composition granule can be one or more in corn, barley, jowar, oat, wheat, the vermicelli particle.
2, carrying out also adding fire retardant carbohydrate particles weight, 1% that accounts for through puffing when modification is handled., fire retardant is one or both in low zinc borate, the antimonous oxide.
