Abstract
A composite thermal insulation material and a preparation method are provided. The thermal insulation material comprises the raw material with the weight proportion is as follows, wherein any of expanded perlite particle, rock wool particle or vermiculite particle is 60 percent to 95 percent, while any of polystyrene particle (PS) or polypropylene particle (PP) is 5 percent to 40 percent. Any of the expanded perlite particle, the rock wool particle or the vermiculite particle and any of the polystyrene particle or the polypropylene particle is taken proportionally to be well mixed, and placed into a closed molding cavity after being uniformly mixed, then heated to 70 DEG C to 150 DEG C to adequately expand the polystyrene and the polypropylene particle which gradually becomes expanded polystyrene (EPS) or polypropylene (EPP), furthermore, the expanded polystyrene or polypropylene is evenly filled, inlaid and bonded in the clearance among the particles of the expanded perlite, rock wool and vermiculite, to cover the bonded particles of the expanded perlite, thus the rock wool and the vermiculite, a composite molding integration is shaped.
Description
Technical field
The present invention relates to a kind of heat-insulation and heat-preservation material that is applicable in heat-insulation wall plate, insulated roof and other wrapping material, relate to a kind of composite heat insulating materials and preparation method thereof specifically.
Background technology
Board-like heat-insulation and heat-preservation material in the existing heat-insulation wall plate is more common to be polystyrene block and expanded pearlite rock beam: (1) polystyrene block be by many polyphenyl small-particles (PS) fixed space back warp add thermal expansion become foam polyphenyl particle (EPS) back and mutually heat seal be an integral body.Though polystyrene block is in light weight, thermal resistance is big, good heat insulating, its non-refractory, easily aging, work-ing life is short.(2) the expanded pearlite rock beam is an expanded perlite granule big based on thermal resistance, good heat insulating, bonds them together by binding agent (as cement, organic gel or inorganic glue etc.).Advantage high temperature resistant, long service life that the expanded pearlite rock beam has, but but have a following deficiency:, reduce the heat insulation effect of expanded pearlite rock beam greatly a) because the much smaller and easy formation " heat bridge " of the thermal resistance of binding agent than expanded perlite granule; B) in addition, these binding agents are all more expensive, make the cost of expanded pearlite rock beam too high.
Summary of the invention
Purpose of the present invention provide at existing weak point in the above-mentioned prior art just a kind of in light weight, thermal resistance is big, high temperature resistant, cost is low, the life-span is long composite heat insulating materials and preparation method thereof.
Purpose of the present invention can realize by following technique measures:
Composite heat insulating materials of the present invention comprises the raw material of following weight ratio: any one 60%-95% in expanded perlite granule, rock wool particle or the vermiculite granule wherein, any one 5%-40% in granules of polystyrene (PS) or the polypropylene GRANULES (PP).
Composite heat insulating materials of the present invention preferably adopts the raw material of following weight ratio to form: expanded perlite granule 60%-95% wherein, granules of polystyrene 5%-40%.
The preparation method of composite heat insulating materials of the present invention may further comprise the steps: get expanded perlite granule in proportion; in rock wool particle or the vermiculite granule any one; in granules of polystyrene or the polypropylene GRANULES any one; carry out thorough mixing; behind the uniform mixing; be placed in the shaping mold cavity of sealing; be heated to 70-150 ℃ afterwards; make the fully foaming of granules of polystyrene (PS) or polypropylene GRANULES (PP); crossfade into polystyrene foamed (EPS) or expanded polypropylene (EPP); and polystyrene foamed or expanded polypropylene after the melting expansion are filled uniformly; inlay; be bonded in expanded perlite granule; in the gap of rock wool particle or vermiculite granule, coat the bonding expanded perlite granule; rock wool particle or vermiculite granule and form a compound molded integral.
Granules of polystyrene or polypropylene GRANULES its volumetric expansion amount in the melt foaming process reaches tens of times; that is to say: when expanded perlite granule, rock wool particle or vermiculite granule have been pushed in particulate state rapid expansion of caused volume when the foaming shape changes again; and then improved the degree of compactness of expanded perlite granule, rock wool particle or vermiculite granule, further increased the intensity and the globality of molded composite material.
Beneficial effect of the present invention is as follows:
Because the raw material that is adopted among the present invention is the material that thermal resistance is big, heat-insulating property is fabulous, when having avoided binding agents such as picture cement or glue to bond perlite after being combined with each other formed " heat bridge ", so heat insulation effect is very good; Simultaneously, the present invention is based on expanded perlite granule, rock wool particle or vermiculite granule, polystyrene or polyacrylic main effect are cohesive actions, and pearlstone, rock wool or vermiculite high temperature resistant, be difficult for the aged characteristic and determined composite heat insulating materials of the present invention not only to have splendid heat-insulating property, and work-ing life is also longer, coupling in work-ing life with the house can satisfy the many tops performance requriements in secular follow-up use; In addition, also because of selected raw material all is a material in light weight, that cost is low, so the present invention has characteristics in light weight, that cost is low equally.
