preparation example Construction

[0024] Some embodiments of the present invention also provide a preparation method of the above-mentioned plant micropowder polymer foaming material, which includes: ethylene-vinyl acetate copolymer, plant micropowder, stearic acid, foaming agent, foaming aid, The kneaded product of the vulcanizing agent and the plant micropowder foaming stabilizer is vulcanized and foamed at a temperature of 160-170°C.

[0025] It should be noted that the vulcanization and foaming process can be carried out better when the raw materials are fully mixed. Therefore, before the vulcanization and foaming process, all raw materials need to be softened and further plasticized to form a gel, so that various raw materials The fluid state can be fully mixed, so that the polymer foam material with better performance can be obtained after vulcanization and foaming. Therefore, various raw materials are kneaded first to obtain a kneaded product, and then vulcanized and foamed.

[0026] Specifically, the ...

Abstract

The invention relates to the field of high-polymer materials, in particular to a superfine plant powder high-polymer foaming material and a preparation method and application thereof. The high-polymerfoaming material is prepared from, by weight, 90-110 parts of plastics, 20-40 parts of superfine plant powder, 0.5-2 parts of stearic acid, 2-8 parts of foaming agents, 0.5-2 parts of foaming additives, 0.3-1.5 parts of vulcanizing agents and 10-20 parts of superfine plant powder foaming stabilizers. The preparation method includes subjecting a mixture of the raw materials to vulcanized foaming at the temperature 160-170 DEG C. The superfine plant powder and other components are subjected to vulcanized foaming proportionally to obtain high-polymer foaming material; with adding of the superfine plant powder foaming stabilizer, the high-polymer foaming material is stabilized, and thus, high-polymer foaming material with high performance is obtained while special functions of the superfine plant powder play roles and biodegradablity of the high-polymer foaming material is reduced.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a plant micropowder polymer foaming material and a preparation method and application thereof. Background technique [0002] At present, there are many polymer foaming materials, and their applications are extremely wide, but the filling materials used are almost all inorganic materials, such as calcium carbonate, silicon dioxide, talcum powder, clay and so on. [0003] Therefore, existing plant materials are also used as fillers, but they have not been used because they can lead to poor stability of polymer foamed materials in foamed materials. Contents of the invention [0004] The object of the present invention includes providing a plant micropowder macromolecule foaming material and its preparation method and application, so as to improve the stability of the macromolecule foaming material when plant materials are used as fillers. [0005] The present invention solves its...
