[0058] Preparation method of anti-slip rotomolding composition 1:

[0059] (1) Inorganic ultra-fine wear-resistant agent treatment

[0060] Add coupling agent, dispersant and lubricant according to the formula, mix at 1000 rpm for 10 minutes, then add 5 parts of silica powder, mix for 5 minutes, discharge and set aside;

[0061] (2) Preparation of the rotomolding composition of the anti-slip layer

[0062] According to the formula, add linear low-density polyethylene, antioxidant, anti-ultraviolet agent, compatibilizer, inorganic ultra-fine wear-resistant agent, and nylon into the mixer at a speed of 1500 rpm for mixing for 10 minutes, and then use Twin-screw extrusion granulation; the temperature range of the extruder is 200°C, and the screw speed is 200 rpm. The particle size is 2.0 mm, the output is 70 kg / hour, and the particles are ground into 40-mesh powder for later use.

Abstract

The invention discloses a skid and scrub resistant rotationally molded product and a preparation method thereof, and belongs to the technical field of rotationally molded materials. The skid and scrub resistant rotationally molded product comprises a low-density polyethylene base and a skid and scrub resistant layer added on the base, and the skid and scrub resistant layer is composed of linear low-density polyethylene, an inorganic wear-resisting agent, a high molecular reinforcing agent and an auxiliary agent. The rotationally molded product is prepared through three steps: processing of the inorganic superfine wear-resisting agent, preparation of a rotational molding composition for the skid and scrub resistant layer, and preparation of the rotationally molded product. The skid and scrub resistant rotationally molded product has smooth inner surface and outer surface, is good in layer combination, and has no warping, no deformation, no foams and no recesses, the scrub-wear volume loss of the product is reduced by 50% or more, and the preparation method of the skid and scrub resistant rotationally molded product is simple, safe and obvious in effect.

Description

technical field [0001] The invention belongs to the technical field of rotational molding materials, and relates to a friction-resistant rotational molding product and a preparation method thereof. Background technique [0002] The large-scale amusement facilities formed by rotomolding not only overcome the previous steel and cement forms that are easy to cause bumps and injuries to children, but also overcome the pollution caused by the migration of harmful substances caused by painting. , develop children's intelligence, increase children's communication ability, and have great benefits for children's growth. However, since the plastic raw material for rotational molding is usually linear low-density polyethylene, which is relatively soft and has poor friction resistance, especially when there are gravel and dust attached to the surface, it will cause deeper damage to the surface of the rotational molding product and affect the color. Once the surface of the plastic produ...
