[0074] Preparation method of anti-slip rotomolding composition 1:

[0075] (1) Inorganic ultra-fine wear-resistant agent treatment

[0076] 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;

[0077] (2) Preparation of the rotomolding composition of the anti-slip layer

[0078] 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 rotational molding product and a preparation method thereof and belongs to the technical field of rotational molding materials. The rotational molding product comprises a linear low-density polyethylene substrate; a slipping and abrasion resisting layer is additionally arranged on the substrate; and the slipping and abrasion resisting layer is composed of linear low-density polyethylene, an inorganic abrasion-resisting agent, a macromolecular enhancing agent and an auxiliary agent. The rotational molding product is prepared through three steps of treating an inorganic ultrafine abrasion-resisting agent, preparing a rotational molding composition of the slipping and abrasion resisting layer, and preparing the slipping and abrasion resisting rotational molding product. The slipping and abrasion resisting rotational molding product has smooth inner and outer surfaces; the combination between layers is good; the rotational molding product has no warping, deformation, air bubbles and concave parts; the scraping abrasion loss volume of the product is reduced by 50% or more; the preparation method of the slipping and abrasion resisting rotational molding product is simple and safe and has an obvious 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...
