Description
Technical field
The present invention relates to polypropylene material preparation field, the good polypropylene board of more particularly to a kind of resistance to low temperature
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 general polypropylene board, with easy aging, intolerant to low
The shortcoming of temperature, service life extreme difference in cold environments.
The content of the invention
The present invention solves the technical problem of the preparation method for providing a kind of good polypropylene board of resistance to low temperature,
By improving the composition proportion of polypropylene board, the resistance to low temperature of sheet material is effectively improved, also can normally be made under -30 DEG C of environment
With the appearance of fragmentation situation will not be catalyzed caused by too low because of temperature.
In order to solve the above technical problems, one aspect of the present invention is：There is provided a kind of resistance to low temperature good
The preparation method of polypropylene board, its preparation process is as follows：Raw material, blended melting are extracted, is extruded, is pressed into plate, cools down, cut
Cut, packaging and storage；The raw material includes：Acrylic resin, foaming agent, nucleator, compatilizer, photomask agent and antioxidant；
The blended melting step is：By the acrylic resin, nucleator, foaming agent blending, melted under the conditions of 220 DEG C, stirring
20min, 180 DEG C are reduced to by temperature, are added after the compatilizer, photomask agent and antioxidant, stirring 15min, by squeezing
Go out machine extrusion, be pressed into plate, be cooled to solidification, cut, and packaging and storage, obtain finished product.
In a preferred embodiment of the present invention, during the blended melting, heating and cooling rate are 8 DEG C/min.
In a preferred embodiment of the present invention, the nucleator is butadiene rubber powder.
In a preferred embodiment of the present invention, the acrylic resin and the nucleator mass ratio are 100：15.
The beneficial effects of the invention are as follows：Composition proportion of the invention by improving polypropylene board, effectively improves sheet material
Resistance to low temperature, also can normally be used under -30 DEG C of environment, going out for fragmentation situation will not be catalyzed caused by too low because of temperature
It is existing.
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 resistance to low temperature, its preparation process is as follows：Extract raw material, blended melting,
Extrude, be pressed into plate, cooling, cutting, packaging and storage；The raw material includes：It is acrylic resin, foaming agent, nucleator, compatible
Agent, photomask agent and antioxidant；The blended melting step is：By 100 parts of acrylic resin, 15 parts of nucleator, foaming agent 5
Part blending, is melted under the conditions of 220 DEG C, stirs 20min, and temperature is reduced into 180 DEG C, adds 8 parts of compatilizer, photomask agent 3
After 5 parts of part and antioxidant, stirring 15min, extruded by extruder, be pressed into plate, be cooled to solidification, cut, and wrap
Load storehouse, obtain finished product.
Further illustrate, at the blended melting stage, heating and cooling rate are 8 DEG C/min, it is possible to increase each proportioning
Material fully merge, improve board composition stability and the uniformity.
Illustrate further, the nucleator is butadiene rubber powder, and acrylic resin and butadiene rubber powder
Mass ratio is 100：15., butadiene rubber has high resiliency, good cryogenic property（Glass transition temperature is -110 DEG C or so）With it is resistance to
The good characteristics such as mill property, resistance to deflection.And its content parameter is close with polypropylene, in practice it has proved that, their compatibility compared with
Good, toughening effect is obvious.100 are pressed with polypropylene powder and butadiene rubber；15（Mass ratio）Blending, the normal temperature punching of gained blend
Hit intensity is higher than virgin pp 6 times, and brittle temperature declines 4 times.While extrusion of the blend than PP, PP/LDPE, PP/EVA etc.
Expansion ratio is all small, and dimensional stability is preferable after shaping.
Composition proportion of the invention by improving polypropylene board, effectively improves the resistance to low temperature of sheet material, in -30 DEG C of rings
It also can normally be used under border, the appearance of fragmentation situation will not be catalyzed caused by too low because of temperature.
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.
