Abstract
The invention discloses a preparation process of a bamboo fiber reinforced polyethylene material. The preparation process is characterized by comprising the following steps of: (1) weighing bamboo fibers, antioxidants, plasticizing agents, lubricating agents and compatilizers in proportion, and then uniformly mixing the substances in a mixer; (2) adding high-density polyethylene resin, low-density polyethylene resin and carbon black to a mixture obtained from the step (1), and uniformly stirring the substances; (3) extruding and granulating the substances obtained from the step (2) through a double-screw extruder. The preparation process disclosed by the invention has the advantages of simplicity, low requirement on equipment and low cost.
Description
Technical field
The present invention relates to technical field of polymer materials, specifically a kind of preparation technology of bamboo fiber reinforcement polythene material.
Background technology
Polyethylene is the simplest macromolecular organic compound of structure, one of most widely used macromolecular material in the world today.Polyethylene is formed by vinyl polymerization, can be made into the wide variety of applications material.Polyethylene is also the main raw of wrapping material.It has the following advantages as wrapping material: polyethylene resists multiple organic solvent, anti-multiple acid and alkali corrosion, but not oxidation-resistance acid, for example nitric acid; The crystallization material, moisture absorption is little, must be fully not dry.But also have some shortcomings, contraction scope and shrinkage value are large, and directivity is obvious, yielding warpage.
Polyethylene can be divided into high density polyethylene(HDPE), medium-density polyethylene and Low Density Polyethylene according to the difference of density.Wherein, it is large that high density polyethylene(HDPE) has rigidity, hardness and physical strength, and low-temperature impact resistance is good, and anti-stress cracking is good, and wear resistance is good, ageing-resistant characteristic.High-density polyethylene resin is cheap, processing characteristics is excellent, and physics and chemical property are all good, water isopolarity solvent is had to good barrier simultaneously, therefore is widely used in wrapping material.
Summary of the invention
The object of the present invention is to provide a kind of preparation technology of bamboo fiber reinforcement polythene material.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of preparation technology of bamboo fiber reinforcement polythene material, is characterized in that, comprises the following steps:
(1) bamboo fibers, oxidation inhibitor, softening agent, lubricant, compatilizer are proportionally mixed after weighing in mixer;
(2) high-density polyethylene resin, ldpe resin and carbon black are added in the mixture in step (1), stir;
(3) material step (2) obtained is by the twin screw extruder extruding pelletization.
The formula of described raw material is, by weight, high-density polyethylene resin 50-60 weight part, ldpe resin 5-10 weight part, bamboo fibers 12-16 weight part, carbon black 5-7 weight part, oxidation inhibitor 0.1-0.5 weight part, softening agent 1-2 weight part, lubricant 2-3 weight part, compatilizer 0.5-1 weight part.
The formula of described raw material is, by weight, high-density polyethylene resin 55 weight parts, ldpe resin 7 weight parts, bamboo fibers 14 weight parts, carbon black 6 weight parts, oxidation inhibitor 0.3 weight part, softening agent 1.5 weight parts, lubricant 2.5 weight parts, compatilizer 0.8 weight part.
