Problems solved by technology

[0003] The above-mentioned polyolefin composition highly filled with inorganic high-efficiency modifiers, the prepared chopsticks have good mechanical properties and performance, but because the notched impact strength is greater than 22J / m, and the bending strength is greater than 52Mpa, the modified polyolefin The use of olefin composition has great limitations, and it needs to be applied to chopsticks with thicker walls, and cannot be applied to thin-walled injection molded tableware

Embodiment 1

[0042] A thin-walled tableware resin for high-speed injection molding, comprising the following raw materials by weight:

[0043]

[0044]

[0045] The preparation method of thin-wall tableware resin for high-speed injection molding comprises the following steps:

[0046] (1) put ceramic powder and shell powder into high-speed mixer for mixing and stirring, then add polymer powder surface treatment agent, carry out surface treatment, and obtain primary material;

[0047] (2) drop remaining raw material into the primary material of step (1), carry out mixing, obtain mixed material;

[0048] (3) The mixture prepared in step (2) is extruded and granulated through a twin-screw extruder to obtain the thin-wall tableware resin for high-speed injection molding.

Abstract

The invention relates to the technical field of tableware resin, in particular to thin-wall tableware resin for high-speed injection molding and a preparation method thereof.The thin-wall tableware resin is prepared from, by weight, 50-55 parts of ceramic powder, 5-10 parts of shell powder, 1-1.5 parts of polymer powder surface treating agent, 0.3-0.5 part of di-tert-butyl peroxide, 1-3 parts of PETS and 35-40 parts of PP polyolefin. The thin-wall tableware resin is suitable for production of a high-speed injection molding machine, the production speed is larger than 5 seconds per mold number, and the thin-wall tableware resin is excellent in mechanical property, high in rigidity, resistant to heat, acid and alkali, oil, folding, tinting strength, solution flow index and other technical indexes and meets the standard of disposable degradation of thin-wall tableware.

Description

technical field [0001] The invention relates to the technical field of tableware resin, in particular to a thin-wall tableware resin for high-speed injection molding and a preparation method thereof. Background technique [0002] Polyolefin is a common plastic resin, which has been widely researched and applied in the field of tableware. For example, the Chinese invention patent with the authorization announcement number CN1164664C: polyolefin composition with high filling inorganic high-efficiency modifier, its preparation method and disposable chopsticks prepared by it, discloses: the polyolefin composition is based on polymer The principle of blending modification and filling modification adopts special inorganic powder surface activation treatment technology and polyolefin / inorganic high-efficiency modifier compound technology. The filling amount of inorganic modifier is as high as 65-75wt%, and the notched impact strength of the material is greater than 22J / m, bending ...
