Abstract
The invention discloses a polyurethane composite plate, which comprises a polyurethane plate, phenolic resin and a non-woven fabric, wherein the phenolic resin is compounded between the polyurethane plate and the non-woven fabric. The polyurethane composite plate has good thermal insulation and sound insulation effects without dust pollution; a great amount of adhesive is not required to be added in the preparation process, so thick odor in the pressing process is avoided; and the product is light.
Description
Technical field
The present invention relates to-kind of Rigid foam polyurethane material, relate in particular to a kind of Rigid foam polyurethane material that is used for the automobile engine heat-insulating sound-insulating.
Background technology
The Rigid foam polyurethane material that is used for the automobile engine heat-insulating sound-insulating at present is to be composited by polyurethane sheet and the adhesive plaster that is soaked with a large amount of glue, and not only cost is high, and bigger at the process moderate stimulation property smell of moulding, pollutes comparatively serious.
Also useful blanket of glass wool is used for the heat-insulating sound-insulating of automobile engine, but owing to glass dust size in the blanket of glass wool is minimum, gets into human body easily, but is difficult for being discharged by human body, and human body skin is had excitant, has understood small red dot after people's one contact of skin sensitivity.Once more, owing to need to add a large amount of adhesives, it is bigger therefore in forming process, to give out penetrating odor in the process of preparation for mineral wool, pollutes comparatively seriously, can not satisfy present VOC (VOC) standard.
Along with China's Manufacturing Industry more and more perfect to environmental quality system and VOC standard, make that polluting comparatively serious automobile-used material needs with the environment-friendly type new material alternative.
Summary of the invention
The present invention provides a kind of Rigid foam polyurethane material.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of Rigid foam polyurethane material comprises polyurethane sheet, phenolic resins and nonwoven, and wherein, phenolic resins is compounded between polyurethane sheet and the nonwoven.
The used phenolic resins of raw material of the present invention is Powdered, during preparation it is sprinkling upon between polyurethane sheet and the nonwoven, and its purposes is the effect of bonding and typing.
In order to prevent phenolic resins infiltration to nonwoven when the solidifying and setting, simultaneously can be better with nonwoven and phenolic resin bonded, above-mentioned Rigid foam polyurethane material also comprises the hot melt adhesive film that is compounded between phenolic resins and the nonwoven.
As preferred version, above-mentioned Rigid foam polyurethane material is followed successively by nonwoven, hot melt adhesive film, phenolic resins, polyurethane sheet, phenolic resins, hot melt adhesive film and nonwoven from top to bottom.
The mass fraction of each layer of the present invention is preferably: nonwoven 23-26 part, hot melt adhesive film 0-13 part, phenolic resins 5-11 part, polyurethane sheet 53-59 part.
The density of polyurethane sheet of the present invention is preferably 14-20kg/m
3
The preparation method of Rigid foam polyurethane material of the present invention does, polyurethane sheet, phenolic resins, hot melt adhesive film and nonwoven are stacked in order, and hot-forming by the method for routine, the temperature of hot pressing can be 160-190 ℃, and the dwell time can be about 35 seconds.
Rigid foam polyurethane material heat-insulating sound-insulating of the present invention is effective, and no dust pollution because it need not to add a large amount of binding agents in the preparation process, therefore in pressing process, do not have too big smell, and product quality is also lighter relatively.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is acoustic absorptivity spectrum curve figure of the present invention.
The specific embodiment
" heat-insulating material is stablized the mensuration heat-flow meter of thermal resistance and related characteristics to thermal conductivity factor mensuration with reference to GB/T 1C295-2008
Method ".
Acoustic absorptivity is measured with reference to ISO10534-2 (respective country standard GB/T18696.2-2002), adopts transfer function method to measure.
As shown in Figure 1, a kind of Rigid foam polyurethane material, by polyurethane sheet, phenolic resins, hot melt adhesive film and nonwoven are multiple
Close and form, promptly the composition of composite board is respectively nonwoven, hot melt adhesive film, phenolic resins, polyurethane sheet, phenolic resins, hot melt adhesive film, nonwoven from top to bottom.The mass fraction of each layer is respectively: 26 parts of nonwoven, 10 parts of hot melt adhesive films, 8 parts in phenolic resins, 56 parts of polyurethane sheets.It is 17kg/m that polyurethane sheet gets density
3
Polyurethane sheet, phenolic resins, hot melt adhesive film and nonwoven are stacked according to said sequence, in 170 ℃ of following hot pressing 35 seconds, moulding.Composite plate thickness is 18mm after the moulding, and thermal conductivity factor (30 ℃ of mean temperatures, 15 ℃ of the temperature difference) is 0.041W/ (mK), and acoustic absorptivity as shown in Figure 2.
