Abstract
The invention discloses phenolic resin and urea resin composite modified plastic, comprising phenolic resin, urea resin and additives, wherein the additives comprise a toughening agent, a plasticizer, a weathering resisting agent, a compatilizer and a coupling agent, the toughening agent is polyvinyl alcohol, the plasticizer is diamyl phthalate, the weathering resisting agent is resorcinol monobenzoate, the compatibilizer is phthalic anhydride, and the coupling agent is vinyl triethoxysilane. The prepared phenolic resin and urea resin composite modified plastic has the effects of weathering resistance, good toughness, excellent dimensional stability and the like.
Description
Technical field
The present invention relates to a kind of plastic formula, be specifically related to the composite modified plastics of a kind of resol and urea-formaldehyde resin.
Background technology
Resol is one of plastics variety of growing most in history, is commonly called as bakelite or bakelite, and outward appearance is tawny or black, is the Typical Representative of thermosetting resin.But resol easily absorbs water, Bakeland electrical property is declined, physical strength reduces, and fragility is large.Urea-formaldehyde resin is the colourless plastics that can be used as molding compound, caking agent etc., by urea and formaldehyde, is prepared.Urea-formaldehyde resin molding compound has been dosed Mierocrystalline cellulose.And hardness, physical strength are good.On the other hand, the shortcoming of have embrittlement, have water-absorbent, dimensional stability is bad, even standingly also often cracks.
Summary of the invention
The object of the present invention is to provide a kind of weather, good toughness, splendid resol and the composite modified plastics of urea-formaldehyde resin of dimensional stability.
Technical scheme of the present invention is, the composite modified plastics of a kind of resol and urea-formaldehyde resin, comprise resol, urea-formaldehyde resin and additive, described additive comprises toughner, softening agent, weather resisting agent, compatilizer and coupling agent, described toughner is polyvinyl alcohol, and described softening agent is diamyl phthalate, described weather resisting agent list phenylformic acid resorcinol, described compatilizer is Tetra hydro Phthalic anhydride, and described coupling agent is vinyltriethoxysilane.
In a preferred embodiment of the present invention, each composition weight percent of the composite modified plastics of described resol and urea-formaldehyde resin is that resol accounts for 37%-50%, urea-formaldehyde resin accounts for 34%-42%, polyvinyl alcohol accounts for 3.6%-4.5%, diamyl phthalate accounts for 2.6%-3.7%, single phenylformic acid resorcinol accounts for 4.2%-5.1%, and Tetra hydro Phthalic anhydride accounts for 3.4%-4.3%, and vinyltriethoxysilane accounts for 2.2%-3.4%.
In a preferred embodiment of the present invention, each composition weight percent of the composite modified plastics of described resol and urea-formaldehyde resin is that resol accounts for 46.3%, urea-formaldehyde resin accounts for 35.8%, polyvinyl alcohol accounts for 3.8%, diamyl phthalate accounts for 2.9%, single phenylformic acid resorcinol accounts for 4.4%, and Tetra hydro Phthalic anhydride accounts for 3.6%, and vinyltriethoxysilane accounts for 3.2%.
Of the present invention is a kind of resol and the composite modified plastics of urea-formaldehyde resin, makes the resol that makes and the composite modified plastics of urea-formaldehyde resin have the effects such as weather, good toughness, dimensional stability be splendid.
Embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Of the present invention is a kind of resol and the composite modified plastics of urea-formaldehyde resin, comprise resol, urea-formaldehyde resin and additive, described additive comprises toughner, softening agent, weather resisting agent, compatilizer and coupling agent, described toughner is polyvinyl alcohol, described softening agent is diamyl phthalate, described weather resisting agent list phenylformic acid resorcinol, described compatilizer is Tetra hydro Phthalic anhydride, described coupling agent is vinyltriethoxysilane.
Further, each composition weight percent of the composite modified plastics of described resol and urea-formaldehyde resin is that resol accounts for 37%-50%, urea-formaldehyde resin accounts for 34%-42%, polyvinyl alcohol accounts for 3.6%-4.5%, diamyl phthalate accounts for 2.6%-3.7%, single phenylformic acid resorcinol accounts for 4.2%-5.1%, and Tetra hydro Phthalic anhydride accounts for 3.4%-4.3%, and vinyltriethoxysilane accounts for 2.2%-3.4%.
Further, each composition weight percent of the composite modified plastics of described resol and urea-formaldehyde resin is that resol accounts for 46.3%, urea-formaldehyde resin accounts for 35.8%, polyvinyl alcohol accounts for 3.8%, diamyl phthalate accounts for 2.9%, single phenylformic acid resorcinol accounts for 4.4%, and Tetra hydro Phthalic anhydride accounts for 3.6%, and vinyltriethoxysilane accounts for 3.2%.
Further, each composition weight percent of the composite modified plastics of described resol and urea-formaldehyde resin is that resol accounts for 41.8%, urea-formaldehyde resin accounts for 39.1%, polyvinyl alcohol accounts for 4.3%, diamyl phthalate accounts for 3.5%, single phenylformic acid resorcinol accounts for 4.9%, and Tetra hydro Phthalic anhydride accounts for 4.1%, and vinyltriethoxysilane accounts for 2.3%.
Of the present invention is a kind of resol and the composite modified plastics of urea-formaldehyde resin, makes the resol that makes and the composite modified plastics of urea-formaldehyde resin have the effects such as weather, good toughness, dimensional stability be splendid.
The foregoing is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
