Abstract
The invention discloses a thermal insulation material, which comprises 10-50 parts by volume of pearlite 30-80 parts by foamed volume of polyurethane, and also comprises an additive accounting for 1-20% of the total weight of the thermal insulation material, the additive comprises, by the total weight of the thermal insulation material, 1-15% of hexabromocyclododecane, 1-5% of polyether polyols and 1-5% of cyclopentane. The invention also provides a preparation method of the thermal insulation material. The perlite is light in mass and large in volume, can replace a large portion of foamed polyurethane volume, while the polyurethane is added into the system for adhesive polymerization, and by use of the technical scheme of the thermal insulation material, the polyurethane foaming cost is saved by 30-50%, compared with conventional polyurethane foaming cost.
Description
Technical field
The present invention relates to a kind of heat insulating material, be specifically related to a kind of foaming thermal-insulating, the invention still further relates to the preparation method of described lagging material.
Background technology
Lagging material generally refers to that thermal conductivity is less than or equal to 0.2 material.In industry and building, adopt good heat preservation technology and material, often can play a multiplier effect.
Wherein organic lagging material mainly contains polyurethane foam, styrofoam, phenol formaldehyde foam etc.The simple polyurethane foam that adopts, cost is higher.
Summary of the invention
The object of the present invention is to provide the lagging material that a kind of weight is low, cost is low.
The present invention is achieved in that
A kind of lagging material, the urethane of the 30-80 volume parts that comprises the perlite of 10-50 volume parts and calculate by the rear volume of foaming, also comprise the additive that accounts for lagging material gross weight 1-20%, described additive comprises hexabromocyclododecane 1-15%, polyether glycol 1-5%, the pentamethylene 1-5% that accounts for lagging material gross weight.
In the present invention, urethane is black, white liquid foam, and it is than great, and cost is high.And perlite is to become a kind of lightweight, multifunctional novel shaped material through expansion, have that apparent density is light, thermal conductivity is low, wettability power is little, and nontoxic, tasteless, fire prevention, lightweight, insulation, heat insulation sound absorbent plate; Roof resisting to external fire exposure and lightweight are antifreeze, shockproof, the material of construction such as filler of fire prevention, radioprotective contour level construction work body of wall; Also for various industrial equipmentss, pipe insulation layer; The inwall of various deep coolings, freezer engineering.The present invention selects this bi-material, just reaches the object of material behavior complementation.In the present invention, perlite quality is light, and volume is large, can replace the volume of polyurathamc greatly, and the urethane adding has played adhesion to polymeric effect in system.And add determining of perlitic volume parts, and be the performance that can either reach lagging material insulation of the present invention, can be combined with viscoelastic polyurethane the intensity of packing lagging material again.Meanwhile, in the application, add hexabromocyclododecane in order to strengthen the fire line of this material; Add polyether glycol in polyurethane foam process, to play froth breaking effect; Adding pentamethylene is in order to freeze and foaming effect.
The present invention also provides the preparation method of described lagging material, is specially:
Urethane adopts black and white material liquid foam to generate, and after additive, black and white feed liquid body are mixed together, inject perlite and black and white material and is cross-linked, and compound enters in mould together subsequently.
Through the long-term research of contriver, find that perlite 70s to 90s after black and white material liquid mixing adds most suitable, now polyurethane foam has started to produce gel, inject after perlite can be rapidly and urethane be cross-linked, when perlite just will suspend separation, urethane is foaming and molding.Because perlite is very light, as first injected perlite, come foaming perlite to suspend, bi-material will be separated, and if inject afterwards, urethane is foaming, perlite also cannot with urethane crosslinks.
By technical scheme of the present invention than the conventional polyurethanes cost-saving 30-50% that foams.Due to different field service requirements separately, can require to regulate voluntarily according to insulation, to meet each own demand.
Embodiment
Embodiment 1
A lagging material, comprises urethane 80%, perlite 15%, and additive 5%, described additive comprises hexabromocyclododecane 3%, polyether glycol 1%, the pentamethylene 1% that accounts for lagging material gross weight.This scheme can be saved 12% cost.
The preparation method of described lagging material is:
Urethane adopts black and white material liquid foam to generate, and after additive, black and white feed liquid body are mixed together, at 70s to 90s injection perlite and black and white material, is cross-linked, and compound enters in mould together subsequently.
Embodiment 2
A lagging material, comprises urethane 50%, perlite 40%, and additive 10%, described additive comprises hexabromocyclododecane 6%, polyether glycol 2%, the pentamethylene 2% that accounts for lagging material gross weight.This scheme can be saved the cost of 25% left and right.
Preparation method is with embodiment 1.
Embodiment 3
A lagging material, comprises urethane 30%, perlite 50%, and additive 20%, described additive comprises hexabromocyclododecane 15%, polyether glycol 2%, the pentamethylene 3% that accounts for lagging material gross weight.This scheme can be saved 40% cost.
Preparation method is with embodiment 1.
Cost-saving example:
Urethane: 16 yuan/kilogram, by the rear cube of 35 kilograms of calculating of foaming, 560 yuan/cube.
Perlite: 100 yuan/cube is low density cargo.
The identical foamed product of cube, as: added 50% perlite, than only having saved 40% cost with urethane, as: added 15% perlite, also than only having saved 12% cost with urethane.
Claims (2)
1. a lagging material, it is characterized in that: comprise the perlite of 10-50 volume parts and by the urethane of the 30-80 volume parts that after foaming, volume calculates, also comprise the additive that accounts for lagging material gross weight 1-20%, described additive comprises hexabromocyclododecane 1-15%, polyether glycol 1-5%, the pentamethylene 1-5% that accounts for lagging material gross weight.
2. the preparation method of lagging material described in claim 1, is characterized in that:
Urethane adopts black and white material liquid foam to generate, and after additive, black and white feed liquid body are mixed together, at 70s to 90s injection perlite and black and white material, is cross-linked, and compound enters in mould together subsequently.
