Abstract

The invention relates to a preparation method of an acrylonitrile-butadiene-styrene (ABS) resin multi-component nano functional drying agent, belonging to the field of preparation of nano environment-friendly functional materials. The preparation method comprises the following steps: after preparing materials according to a certain weight ratio, 1, putting nano calcium carbonate into a mixing machine, and performing low-speed mixing; 2, putting an antistatic agent into the mixing machine, performing low-speed mixing for 3 minutes, and performing antistatic treatment on the nano calcium carbonate; 3, putting a coupling agent into the nano calcium carbonate subjected to antistatic treatment, performing low-speed mixing for 10 minutes, and performing primary calcium carbonate coating treatment; 4, putting ABS and remaining assistant into the nano calcium carbonate subjected to primary coating treatment, performing high-speed mixing for 5 minutes, and performing secondary calcium carbonate coating treatment; and 5, transferring the mixed materials into a double screw extruder, extruding, and cutting into uniform particles. According to the invention, the production procedures are simplified, the energy consumption is lowered, the production efficiency is enhanced, and the tensile toughness, processing flowability and aging resistance of the product are improved; and the addition of the drying agent within a certain proportional range can not increase the weight of the product.

Description

technical field [0001] The invention belongs to a method for preparing a nano-environmental protection functional material, in particular to a method for preparing a high-efficiency functional desiccant by using a multi-unit nano-level ABS resin material. Background technique [0002] ABS, commonly known as acrylonitrile-butadiene-styrene, is a resin made of three monomers of acrylonitrile, butadiene and styrene. Due to the presence of strong polar nitrile groups in its chemical molecules, ABS The resin has a water absorption rate of 0.2% to 0.8%, so the resin produced under normal circumstances will contain a certain amount of water. Users need to spend 2 to 4 hours before processing, and use an oven to dry ABS resin at a temperature of 80°C to 85°C. Another conventional method is to use a drying hopper to dry at 80°C for 1 to 2 hours to remove moisture from the ABS resin. The above two methods are time-consuming and energy-consuming. Traditional methods must be improved...
