Abstract

The invention discloses an anti-aging foaming material and a preparation method thereof. The anti-aging foaming material is prepared from the following components in parts by weight: 90-100 parts of high-melt-strength polypropylene, 8-10 parts of dried lacquer, 12-18 parts of vermiculite schist seu, 6-8 parts of manganese borate, 5-7 parts of ethyltrichlorosilane, 2-4 parts of diallyl phthalate, 3-8 parts of azodicarbonamide, 1-3 parts of N-phenyl-alpha-aniline and 0.5-0.7 part of ethylene thiourea. The foaming material has excellent mechanical performance, excellent aging resistance, excellent thermal and sound insulation performance, relatively good cell shape and uniform cell distribution, and the material quality is greatly improved.

Description

technical field [0001] The invention belongs to the field of foam material production, and in particular relates to an aging-resistant foam material and a preparation method thereof. Background technique [0002] Polymer foaming material refers to a type of material that uses polymer as the matrix but is filled with tiny pores inside. Its preparation method is generally by adding a foaming agent (physical foaming agent, chemical foaming agent or compound foaming agent) to the plastic. Foaming agent), while adding some processing aids, through intermittent foaming, extrusion foaming, injection foaming and other processes to process and shape. Because there are a large number of gas micropores distributed in the plastic matrix, the polymer foam material has excellent properties such as low density, sound absorption, shock absorption, and heat preservation, and can save costs and resources. Since the advent of polymer foaming materials in the early 20th century, its types have...
