It is 70~100 DEG C, revolving speed is 400~600r/min, mixes 10~20min, obtains the environmental protection for improving PVC injection molding pipe part performance
Auxiliary agent crude product；
S2: the environmentally friendly auxiliary agent crude product for being used to improve PVC injection molding pipe part performance prepared by step S2 is sieved after grinding, and is gone
Except partial size is greater than the sieve residue of 80 mesh, the environmentally friendly auxiliary agent finished product for improving PVC injection molding pipe part performance is obtained.
Further preferred technical solution is in addition, further include step S3 after the step S2: use prepared by step S2
It is packed in the environmentally friendly auxiliary agent finished product for improving PVC injection molding pipe part performance according to the specification of 20kg/ bags or 25kg/ bags.
The advantages and beneficial effects of the present invention are:
1, the various material compositions in the present invention meet environment protection requirement, and then it is excellent to ensure that the environmental protection auxiliary agent has
Good environmental-protecting performance.
2, the dispersion performance of organic nano imvite is preferable, and then organic nano imvite can be of uniform size with nanoscale
It is scattered in environmentally friendly auxiliary agent, while organic nano imvite keeps dispersing uniformity of the environmentally friendly auxiliary agent in PVC pipe preferable, guarantees
The homogeneous property of PVC pipe, improves the overall flexibility and mechanical strength of PVC pipe；In addition organic nano imvite with
It is formed between polyvinyl chloride resin in PVC pipe and is closely combined, can effectively hindered the warm-up movement of polyvinyl chloride resin strand, make PVC
The heat resistance of pipe fitting is obviously improved.
3, ACR processing aid can be obviously shortened fusion time, accelerate melting, promote plasticizing；Polyvinyl chloride resin can be effectively reduced
Melt processing temperature, improve the weather resistance of product simultaneously on the basis of slightly energy-efficient；Due to squeezing when can effectively be molded
Pressure oscillation caused by forming and flowing scar, effectively avoid generating the cosmetic issues such as ripple, zebra stripes；It can be improved product
Surface gloss, due to be plasticized uniformly, while can assist improve product tensile strength, impact strength, extension at break
The mechanical properties such as rate.
4, AS-935 processing aid is combined by methyl methacrylate and a variety of inside and outside lubrication esters compounds, is belonged to
" core-shell structure copolymer " structure, outer lubrication ester type compound can make the reduction of Melts torque, extend fusion time；Interior lubrication esters chemical combination
Object is good with polyvinyl chloride resin compatibility, and PVC pipe apparent mass can be improved, this is because AS-935 processing aid can make polyvinyl chloride resin molten
The gelation degree of body increases, and fluidity of molten improves, then in injection filling mould, the friction level of melt and mould inner wall can be reduced,
Therefore the glossiness of PVC pipe product surface is more preferable, and whiteness is higher.
5, under the action of compatilizer maleic anhydride grafted polyethylene, polyvinyl chloride resin molecule, which is able to enter organic nano and covers, to be taken off
In the intercalation of soil, it was demonstrated that organic nano imvite and polyvinyl chloride resin form close combination, can be obviously improved PVC pipe
Heat resistance.
6, the addition of coupling agent enables organic nano imvite to combine closely in PVC pipe with polyvinyl chloride resin, further
Improve the heat resistance of PVC pipe.
