Embodiment 1
[0026] A method for modifying anti-skid and wear resistance of lightweight rubber shoes, characterized in that it comprises the following steps, and the following raw materials are calculated in parts by weight:
[0027] (1) Surface pretreatment of aramid staple fibers: first impregnate 5 parts of aramid staple fibers with acetone, ultrasonically wash them at 40°C for 2 hours, then put them into a 10% sodium hydroxide solution and stir for 30 minutes, then Wash with deionized water until neutral, and dry in a blast drying oven at 60°C;
[0028] Put the citric acid-sodium citrate buffer solution with a pH of 5 into a water bath at 50°C for heating, pour 0.03 parts of xylanase into it and stir for 10 minutes, then add the aramid staple fiber obtained above for 5 hours, wash with water until neutral, Put it into a drying oven at 70°C for drying to obtain surface-pretreated aramid staple fibers;
[0029] Coating treatment of aramid staple fiber: Mix 5 parts of epoxy resin E51 and...

Abstract
The invention discloses an anti-slip wear-resistant modification method for lightweight rubber shoes. The anti-slip wear-resistant modification method includes the steps that epoxy resin E51 and imidazole are mixed, acetone is added, stirring and dissolving are conducted, then surface-pretreated aramid short fibers are added, after infiltration, an acetone solution and part of cured epoxy resin are dried in an oven, and coated aramid short fibers are obtained; ethylene glycol and sodium tripolyphosphate are added into deionized water, even stirring is conducted, then pretreated modified coal ash and modified nano-calcium carbonate are added, and through high-speed dispersion wed modification, modified anti-slip aggregates are obtained; and nylon 6 is dried in an air dry oven, put into a rheometer to be molten, fully pretreated and plasticized, a rubber compound, the coated aramid short fibers and the modified anti-slip aggregates are added to be evenly mixed, during addition and discharging, nitrogen is introduced for protection, and then the lightweight rubber shoes are manufactured according to a conventional production method.
Description
technical field [0001] The invention belongs to the field of processing light rubber shoes, and in particular relates to a non-slip and wear-resistant modification method for lightweight rubber shoes. Background technique [0002] Plastic shoes, also known as all-plastic shoes, are shoes made of synthetic resin as the main raw material. Plastic shoes are divided into plastic sandals and plastic slippers according to their usage. Rubber shoes are a kind of shoes, with rubber as the sole or upper, water shoes generally also use rubber shoes, the earliest rubber shoes in my country are the famous "Jiefang brand rubber-soled shoes" or "Jiefang shoes", which are characterized by cheap price and simple production , comfortable and durable to wear, it is actually a good product in shoes. However, most of the commercially available lightweight rubber shoes have the defects of poor anti-skid wear resistance and poor moisture absorption and air permeability. [0003] In the present ...
