Abstract
The invention discloses an extrusion-molded thermal-insulation plate and a preparation method thereof. The extrusion-molded thermal-insulation plate is prepared from 180-200 weight parts of polystyrene, 3-5 weight parts of Freon, 1-3 weight parts of talcum powder, 3-5 weight parts of Freon, 32-34 weight parts of modified loess powder, 55-60 weight parts of nanometer diatomite powder, 4-5 weight parts of alum powder, 2-3 weight parts of ammonium benzoate, 2-3 weight parts of lignosulfonate, and 3-5 weight parts of methyl triethoxysilane. The extrusion-molded thermal-insulation plate has high strength, light weight, low heat conductivity coefficient, good heat absorptivity and corrosion resistance, can be prepared simply and used conveniently, can replace a polystyrene foam board, an extrusion-molded plate and a thermal-insulation system slurry particle thermal-insulation plate, and is suitable for industrial batch production.
Description
Technical field
The present invention relates to a kind of wallboard, more particularly, is a kind of extruded plastic thermal insulation thermal insulation board and preparation method thereof.
Background technology
The building construction of building construction, particularly extremely frigid zones, the amount of heat in building scatters and disappears by roof and body of wall.Therefore, need to pave warming plate on roof and exterior wall, play the effect of heat insulating and save energy.Existing plastic extrusion heated board, has the shortcoming that intensity is low, resistance to compression is low, density is low, resistance to deterioration is weak, cost is high, need to have new product to emerge, and participates in the competition.
Summary of the invention
The object of this invention is to provide a kind of extruded plastic thermal insulation thermal insulation board and preparation method thereof.
The technical solution adopted in the present invention is:
, it is characterized in that being made by the raw material of following weight part:
Polystyrene 180-200 ,Fu Lyons 3-5, talcum powder 1-3, freonll-11 3-5, modified Loess powder 32-34, nano diatomite powder 55-60, alum powder 4-5, phenylformic acid amine 2-3, sulfonated lignin 2-3, Union carbide A-162 3-5;
Described modified Loess powder is made by the raw material of following weight part: loess 100-120, plant ash 30-40, used oil 10-12, starch 10-12, Sodium dodecylbenzene sulfonate 1-2, aluminium powder 0.2-0.3, water are appropriate;
Preparation method is: loess is calcined to 2-3 hour at 460-480 ℃, grinding powder; Starch, Sodium dodecylbenzene sulfonate are joined in suitable quantity of water, be heated into pasty state; In sticking with paste, add described calcining loess powder, plant ash, aluminium powder, used oil, mix and blend 40-50 minute, sends in 60-70 ℃ of drying room and dries, and is broken into coarse particles, sifts out the coarse particles of 1-3mm.
The preparation method of described extruded plastic thermal insulation thermal insulation board, is characterized in that comprising the following steps:
(1) modified Loess powder, nano diatomite powder, alum powder, talcum powder, phenylformic acid amine, sulfonated lignin, Union carbide A-162 are mixed, at 60-75 ℃, stir;
(2) then by polystyrene and step (1) mixing of materials, be heated to 190-235 ℃; Make each material melting and mixing, form polymer melt; Then add freonll-11 to be uniformly mixed; Melt is cooled to 100-125 ℃, then, sends into extruding machine, extrusion moulding.
It is high that the present invention has intensity, and quality is light, the feature that thermal conductivity is low, and intensity is high, and heat absorptivity is good, protection against corrosion, preparation is simple, and easy construction, can replace polystyrene foam plate, extruded sheet and heat insulation system pulp particle warming plate etc., is suitable for industrialized mass production.
