Various moulding process, molding processibility is good；It is good in view of its moulding processability, but the product durability energy after molding
Generally, premature aging can be led to by being exposed to the sun for a long time, cause service life of short duration, influence to use.
Invention content
(1) technical problems to be solved
The problem to be solved in the present invention is to provide a kind of production method of LDPE mixtures, is considered in the prior art with overcoming
It is good to its moulding processability, but the product durability after molding can generally, premature aging can be led to for a long time by being exposed to the sun,
The defects of causing service life of short duration, influencing to use.
(2) technical solution
To solve the technical problem, a kind of production method of LDPE mixtures of the invention includes the following steps：
Step 1 chooses tubbing 15-18% in LDPE big tubbing 58-62%, LDPE according to mass ratio, LDPE raw materials 5-
8%, grey Masterbatch 0.6-0.8%, plasticized modifier 5-6%, deoxidation agent 1-3%；
Step 2 stirs evenly above-mentioned raw material, obtains mixture X；
Mixture X is placed in extruder after once being melted and squeezes out by step 3, and compression melt zone temperature is 180-
190 DEG C, fluxing zone temperature is 210-220 DEG C, and discharging die temperature is 200-210 DEG C；
The material that extruder squeezes out is carried out stage filtering by step 4 by 200 mesh mesh sheet to extruded stock；
Extruded stock after being filtered by single order is placed in subsidiary engine after carrying out second melting and squeezes out by step 5, compression melting
