Abstract
The invention discloses a kind of high-density polycthylene grafted copolymer and its reactive extrursion preparation method, which is made of the components of following parts：100 parts by weight of high density polyethylene (HDPE), tetrahydrophthalic anhydride 5-10 parts by weight, diethyl maleate 1-5 parts by weight, initiator 0.2-0.8 parts by weight, catalyst 0.1-0.2 parts by weight.The present invention is that the HDPE after graft reaction obtains functionalization occurs with alkene and acid anhydrides in HDPE extrusion process, when combining titanium dioxide to use, the amount of addition titanium dioxide can be up to 40% or more of the HDPE dosage after functionalization, and the product that the HDPE after functionalization and titanium dioxide are mixed with has excellent physical mechanical property.
Description
Technical field
The invention belongs to chemical technology field, it is related to a kind of high-density polycthylene grafted copolymer and its reactive extrursion preparation
Method.
Background technique
High density polyethylene (HDPE) (HDPE) is white powder or granular product.It is nontoxic, it is tasteless, crystallinity be 80%~
90%, softening point is 35 DEG C of 125~l, using temperature up to 100 DEG C；Hardness, tensile strength and creep properties are poly- better than low-density
Ethylene；Wearability, electrical insulating property, toughness and cold resistance are preferable；Chemical stability is good, at room temperature, has insoluble in any
Solvent, the corrosion of acid and alkali resistance and various salts；Film is small to the permeability of vapor and air, and water imbibition is low；Resistance to ag(e)ing
Can be poor, environmental stress crack resistance can be such that its performance declines not as good as low density polyethylene (LDPE), especially thermal oxidation, so resin
It is middle that people's antioxidant and ultraviolet absorbing agent etc. must be added to improve the deficiency of this respect.Density polyethylene film with high is under stress condition
Heat distortion temperature is lower.Therefore, high density polyethylene (HDPE) is that a kind of crystallinity is high, nonpolar thermoplastic resin, is had good
Physical mechanical property, but it is poor in conjunction with filler, such as in order to increase whiteness, needs to add mass filler (such as titanium dioxide)
When, physical mechanical property decline is larger.
Summary of the invention
