Description
Technical field
The present invention relates to polypropylene board preparation field, the good polypropylene board of more particularly to a kind of comprehensive mechanical property
Preparation method.
Background technology
Polypropylene, be by propylene polymerization prepared by a kind of thermoplastic resin.It is divided into isotactic poly- third by methyl arrangement position
Three kinds of alkene, random polypropylene and syndiotactic polypropylene, the same side that methyl is arranged in molecular backbone claims isotactic polypropylene, if methyl without
The both sides for being arranged in molecular backbone of order claim random polypropylene, gather when methyl is arranged alternately in advise between the both sides of molecular backbone claim
Propylene.In the acrylic resin of general industry production, isotactic structural content is about 95%, and remaining is random or syndiotactic polypropylene.Work
Industry product is using isotactic thing as main component.Polypropylene is also including the copolymer of propylene and a small amount of ethene.It is usually translucent
Colorless solid, odorless is nontoxic.Heat-resisting, corrosion-resistant, product can be its outstanding advantages with moise-heat sterilization.Because its is nontoxic, heat-resisting, resistance to
The characteristics of corrosion, in anticorrosion equipment field using relatively broad.But common polypropylene board due to polypropylene material in itself
Characteristic, impact strength, fracture elongation, low-temperature brittle point be all undesirable, therefore, develops a kind of comprehensive mechanical property good
Polypropylene board be one need solution the problem of.
The content of the invention
The present invention solves the technical problem of the preparation side for providing a kind of good polypropylene board of comprehensive mechanical property
Method, can effectively improve impact strength, fracture elongation, toughness and the dimensional stability of polypropylene board, the brittle temperature of reduction
Degree, greatly improves the comprehensive mechanical property of product.
In order to solve the above technical problems, one aspect of the present invention is：There is provided a kind of comprehensive mechanical property good
Polypropylene board preparation method, its preparation process is as follows：Raw material is extracted, blended melting, extrudes, is pressed into plate, cools down, cut
Cut, packaging and storage；The raw material includes：Acrylic resin, foaming agent, nucleator, compatilizer and antioxidant；By described poly- third
After olefine resin, foaming agent and the nucleator blended melting under the conditions of 250 DEG C, keeping temperature 30min, 200 DEG C are cooled to, institute is added
State after compatilizer and antioxidant, keeping temperature 20min, extruded by extruder, cut after being pressed into plate, cooling, and
Packaging and storage, obtains finished product.
In a preferred embodiment of the present invention, the preparation method of the good polypropylene board of described comprehensive mechanical property,
The raw material proportioning is：100-120 parts of acrylic resin, 50-70 parts of foaming agent, 15-20 parts of nucleator, 30-50 parts of compatilizer
With 10-20 parts of antioxidant.
In a preferred embodiment of the present invention, the preparation method of the good polypropylene board of described comprehensive mechanical property,
Characterized in that, the nucleator composition is the butadiene-styrene rubber of block copolymer form.
The beneficial effects of the invention are as follows：The present invention can effectively improve the impact strength of polypropylene board, extension
Rate, toughness and dimensional stability, reduce brittle temperature, greatly improve the comprehensive mechanical property of product.
Embodiment
Presently preferred embodiments of the present invention is described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that apparent clearly being defined so as to be made to protection scope of the present invention.
The embodiment of the present invention includes：
A kind of preparation method of the good polypropylene board of comprehensive mechanical property, its preparation process is as follows：Raw material is extracted, blending is molten
Melt, extrude, being pressed into plate, cooling, cutting, packaging and storage；The raw material includes：Acrylic resin, foaming agent, nucleator, phase
Hold agent and antioxidant；By the acrylic resin, foaming agent and nucleator under the conditions of 250 DEG C blended melting, keeping temperature
After 30min, 200 DEG C are cooled to 5 DEG C/min speed, is added after the compatilizer and antioxidant, keeping temperature 20min,
Extruded by extruder, be pressed into plate, sheet material size is cut according to customer demand after cooling, and packaging and storage, obtain
Finished product.
Further illustrate, the preparation method of the good polypropylene board of comprehensive mechanical property, the raw material proportioning is：Polypropylene
10-20 parts of 100-120 parts of resin, 50-70 parts of foaming agent, 15-20 parts of nucleator, 30-50 parts of compatilizer and antioxidant.Wherein
Nucleator composition is the butadiene-styrene rubber of block copolymer form.The butadiene-styrene rubber of block copolymer form has high resiliency, resistance to low
The features such as warm nature, while it is with vulcanization rubber and thermoplastic premium properties.Research shows, polypropylene/block copolymer
The impact strength of the butadiene-styrene rubber system of form, elongation at break are with the increasing of the butadiene-styrene rubber addition of block copolymer form
Plus and step up, the butadiene-styrene rubber content of block copolymer form is at 10 to 15 parts, and the comprehensive mechanical property of blend is most
It is good.
The present invention can effectively improve impact strength, fracture elongation, toughness and the dimensional stability of polypropylene board,
Brittle temperature is reduced, the comprehensive mechanical property of product is greatly improved.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
Equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks
Domain, is included within the scope of the present invention.
