Problems solved by technology

Such a large amount of production has attracted the attention of many industries. If only incineration or pit burial is used, it will not only lead to waste of resources, but also pollute the environment, which is not in line with today's scientific development of efficient recycling of resources.

Abstract

The invention discloses glue taking waste argil as a filler and softener, and belongs to the field of rubber. The glue is prepared from natural rubber or butadiene styrene rubber serving as a main raw material by steps of drying the waste argil serving as the filler and softener, mixing, plastifying crude rubber, mixing masterbatch, mixing the crude rubber and vulcanizing. The glue comprises the following raw materials in part by weight: 100 parts of natural rubber or butadiene styrene rubber, 2.5 to 5.5 parts of zinc oxide, 1.5 to 4.0 parts of stearic acid, 1.5 to 3.0 parts of sulfur, 0.8 to 1.2 parts of anti-aging agent D, 15 to 75 parts of waste argil, and 0.5 to 0.7 part of accelerator DM or 0.8 to 1.2 parts of accelerator CZ. The invention has the advantages that: the waste argil has low cost and can be used as the filler and softener, so the production cost of the glue is saved; waste and environmental pollution are reduced, the waste of the waste argil is reduced, and the environmental pollution caused by accumulating, landfilling and burning is reduced simultaneously; and compared with glue taking argil in the same parts as the waste argil as the filler and aromatic hydrocarbon oil as the softener, the glue has higher performance.

Description

technical field [0001] The invention relates to the technical field of polymer materials. Specifically, waste clay is used as a filler and a softener as a rubber compound. Background technique [0002] Activated clay is mainly used for oil decolorization. Activated clay is a highly active adsorbent processed from bentonite as raw material. It is widely used in decolorization of oil industry. The decolorized clay loses its activity and can no longer be used as a decolorizing agent, and becomes a dark brown powdery solid residue, which sometimes sticks into blocks and becomes waste clay. Bleaching waste bleaching clay is the leftovers produced during the refining process of vegetable oils. It is a by-product of oil processing plants. It contains 20%-40% oil and has a mesh size of 80-100 mesh. It is a precious resource. The main component is SiO 2 、Al 2 o 3 , Fe 2 o 3 , MgO, Na 2 O, CaO, K 2 O, neutral oils, non-hydratable phospholipids, natural pigments, fatty acids a...
