The invention discloses an application of high-pressure polyethylene material, wherein the material is used for producing angle bead. The high-pressure polyethylene material in the invention is produced from specific proportioning of the materials, and the angle bead produced from the high-pressure polyethylene material has high strength, good thermostability, creep resistance, abrasive resistance and fatigue resistance.
Description
Technical field
The invention belongs to the protecting materials field, more specifically relate to a kind of corner protector of high-pressure polyethylene material.
Background technology
Corner protector is the corner protective packing that is used for product, and protection article, carton, wooden case etc. are avoided extraneous extruding and damaged damage.Modern packaging mainly contains two kinds on plastics and paper, promptly is Plastic protective corner and corrugated board corner protector, and these two kinds of products are widely used in the every profession and trade logistics transportation now.
The finishing corner protector is widely used in the construction in indoor and outdoor corner, and construction can not only guarantee straight attractive in appearance, the raising speed of application of lines in corner by corner protector, and has effectively strengthened the firm degree in corner, plays the effect of crashproof anti-collision.Use the corner protector construction can also significantly reduce working strength of workers, shorten the engineering time, reduce engineering cost; The corner that high-intensity section bar is embedded in indoor and outdoor is located, and also can play the effect of stiffening web, improves the crashproof intensity in corner.
Summary of the invention
The object of the present invention is to provide a kind of corner protector of high-pressure polyethylene material, the corner protector intensity of the high-pressure polyethylene material of producing through the specified raw material proportioning is high, has good thermostability, creep resistance, wear resistance and fatigue resistence.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
The corner protector of this high-pressure polyethylene material is that ethylene-vinyl acetate copolymer, lime carbonate, blowing agent AC, crosslink agent DCP, Triple Pressed Stearic Acid, the zinc oxide of 5-18% is formed by high-pressure polyethylene, VA content; The mass fraction of each component is: high-pressure polyethylene 60-70 part, VA content are ethylene-vinyl acetate copolymer 10-30 part, lime carbonate 20-30 part, blowing agent AC 2-5 part, crosslink agent DCP 0.6-0.7 part, Triple Pressed Stearic Acid 1-1.5 part, zinc oxide 1-1.5 parts of 5-18%.
The preparation method of the corner protector of this high-pressure polyethylene material specifically may further comprise the steps:
(1) batch mixing: by the proportioning raw materials raw materials weighing, will other raw material except that blowing agent AC and crosslink agent DCP all drop in the high-speed mixer and mix discharging when temperature reaches 120 ℃;
(2) banburying: with step (1) mixed raw materials; Poured in the Banbury mixer banburying 5-7 minute, and when treating that temperature reaches 100-102 ℃, added blowing agent AC and bridging agent; Started the Banbury mixer banburying once more 5-7 minute; When temperature continued to be elevated to 108-110 ℃, all raw materials mixed, and pour out material;
(3) open refining: the compound that banburying is good is plasticated in two roller mills, and preceding roll temperature 75-85 ℃, back roll temperature 70-80 ℃, time 1-3 minute, slice thickness was the 1-1.5 millimeter;
(4) foaming: foaming is 25-30 minute in the thermostat container that the sheet work in-process input that will plasticate is 150-163 ℃;
(5) cold pressing: the sheet material after will foaming is put into the tapering mould at 80-90 degree angle while hot immediately and was colded pressing 10-15 minute for 30-40 ℃;
(6) deburring: finished product is a kind of corner protector with 87 degree angles, and each color even is consistent.
Remarkable advantage of the present invention is:
The corner protector intensity of the high-pressure polyethylene material of (1) producing through the specified raw material proportioning is high, has good thermostability, creep resistance, wear resistance and fatigue resistence.
(2) prescription of the present invention has solved this technical barrier, if the too soft wrinkle that has been easy to is expected at two vertical angles when promptly colding pressing at degree of depth angle, material is easy to cracking too firmly.
(3) intensity and the elasticity of the corner protector of the high-pressure polyethylene material of the present invention's production have reached an ideal balance, and is with low cost with the rubber phase ratio that equivalent environment uses down, has remarkable economical and social benefit.
