Description
Technical field
The invention belongs to macromolecular material auxiliary agent technical field, by adding different cultivars, difference in functionality, various dose
Various auxiliary agents realize the performance improvement of macromolecular material makrolon.Composite assistant of the present invention be applicable to as makrolon,
Polyester, Polyamide Engineering Plastic and polyethylene, polypropylene, polystyrene, polymethyl methacrylate general-purpose plastics etc. polymerize
Thing, is to be related to a kind of preparation method for polycarbonate modified middle composite assistant.
Background technology
Makrolon (abbreviation PC) is widely used in building material industry, auto manufacturing, medicine equipment and aviation for a long time
The fields such as space flight.Due to the particularity on polycarbonate structure, as makrolon, polyformaldehyde, polyamide, thermoplastic
Growth rate most fast, the second largest engineering plastics after nylon in the five large-engineering plastics such as polyester, Noryl.Poly- carbonic acid
Ester water white transparency, heat-resisting, shock resistance is fire-retardant BI grades, weak acid resistant, resistance to weak base, resistance to neutral oil, not ultraviolet resistance, resistance to intolerant to highly basic
Hydrolytic stability is not high enough, to notch sensitive, and resistance to organic chemistry moral character, resistance to scratch is poor, and meeting in ultraviolet is exposed to for a long time
Jaundice.Therefore makrolon is modified using various technologies, be just particularly important.Modified PC materials, with more
Big application value and broader practice category.In rubber and plastic industry, ultraviolet can be absorbed extensively using ultra-violet absorber, is waved
The low characteristic of hair property, the outstanding tool effect in transparent article and the engineering plastics of high temperature process.Ultra-violet absorber is applied to engineering
The main function that plastics make auxiliary agent is：Improve plastic products yellowing-resistant and anti-light aging performance, the light for improving plastic products is stable
Property.General ultra-violet absorber is used in combination with antioxidant, with good synergy.Therefore, by ultra-violet absorber and other
Pluronic polymer is compounded, and can give full play to the cooperative effect of material, makrolon is had higher antioxidant and anti-light
While old property, the heat endurance of makrolon is greatly improved again.
The content of the invention
It is an object of the invention to provide a kind of composite assistant, it can be effectively improved product after making an addition in makrolon
Inoxidizability, anti-light aging, impact resistance and wearability.It is a further object of the present invention to provide the preparation side of the composite assistant
Method.
Contain 40-50 parts of antioxidant of mass fraction in composite assistant of the present invention.Such as Hinered phenols：2,6- three-level butyl -4-
Methylphenol or double-(3,5- three-level butyl -4- hydroxy phenyls) thioether.Antioxidant is otherwise known as " age resistor ", and main purpose is
Delay the oxidizing process and speed of makrolon, prevent its aging, keep the premium properties of material, can be smoothed out adding
Work, extends the service life of product.
Aid anti-oxidants containing 40-50 parts of mass fraction in composite assistant of the present invention.Such as thio-2 acid di esters auxiliary
The double Lauryl Alcohol esters of antioxidant or double ten four carbon alcohols esters；Or the double octadecyl season amylene tetrols of phosphorous acid esters auxiliary antioxidant are double
Phosphite ester.There is synergy or antagonism between various antioxidant, it is actually used in often according to the species of engineering plastics,
Purposes and processing method, using the length of various auxiliary agents, are used cooperatively, with procreative collaboration effect.It can not only enhance product performance,
Strengthen antioxidant effect, can also reduce cost.
Contain 10-15 parts of ultra-violet absorbers of mass fraction, such as triazine-based ultraviolet absorbent in composite assistant of the present invention
2- (double (2,4- the 3,5-dimethylphenyls) -1,3,5- triazine -2- bases of 4,6-) -5- octyloxies phenol or 2- (4,6- diphenyl -1,3,5- three
Piperazine -2- bases) -5- n-hexane epoxide phenol or Benzotriazole Ultraviolet Stabilizer 2- (2'- hydroxyl -3'- tertiary butyl -5'- methyl
Phenyl) -5- chlorobenzotriazoles or 2- (2- hydroxyl -3,5- di-tert-pentyl-phenyls) BTA.Ultra-violet absorber is alternative
Ground absorbs the ultraviolet of high-energy, is allowed to become harmless energy and discharges or consume.Benzotriazole Ultraviolet Stabilizer is
A more kind of current domestic application.But it is purple that the application effect of triazine-based ultraviolet absorbent is substantially better than benzotriazole
Ultraviolet absorbers.Particularly ultra-violet absorber UV-1577 is a kind of new s-triazine ultraviolet absorber, with very low
Volatility, be particularly suitable for use in engineering plastics, the material such as makrolon is carried with polymer and other additive compatibilities very well
The lasting light stablizing effect of high product.
Fluorescent whitening agent containing 1-5 parts of mass fraction in composite assistant of the present invention.Such as benzoxazole fluorescent bleaches
2,2'- (4,4'- diphenylethyllenes -) dibenzoxazines or 2,5- pairs-(the 5- tert-butyl group -2- benzoxazolyls) thiophene.Fluorescence increases
White agent is a kind of fluorescent dye, and it can absorb sightless ultraviolet light and be converted to the relatively low blue violet light of energy, offset in matrix
It is undesired slightly yellow, so that product visually produces pure white, dazzling effect, improve the aesthetic property of product.
By above-mentioned each component raw material in following ratio（Mass fraction）：
40-50 parts of antioxidant
40-50 parts of aid anti-oxidants
10-15 parts of ultra-violet absorber
1-5 parts of fluorescent whitening agent
It is sufficiently mixed, stirs in high mixer, take each component after stirring to granulate, obtain particle, by obtained
Grain sieving, you can obtain for polycarbonate modified composite assistant.The composite assistant is imitated by the collaboration between each auxiliary agent
Should, effectively reduce total addition usage amount.
