Abstract

The invention discloses a liquid curtain type premixer for toughened modified plastic production, and belongs to the field of related equipment for modified plastic production. The liquid curtain type premixer for toughened modified plastic production is characterized in that molten plastic naturally flows downwards along the outer edge of a liquid curtain powder suction cover to form a dispersed and uniform plastic liquid curtain, and meanwhile, air flow is mixed with modifier powder, the mixture is introduced into a powder scattering cylinder; under the action of the air flow, the modifier powder is sprayed to the plastic liquid curtain in a flowing-down state in a spurting mode, adheres to the plastic liquid and flows down along with the plastic liquid. According to the liquid curtain type premixer for toughened modified plastic production, the uniform premixing operation of the modifier powder and the molten plastic is synchronously completed, and the mixing difficulty and time of the molten plastic and the modifier powder in the later period are greatly reduced, so that the production efficiency and quality of the modified plastic are effectively improved; in the plastic melting and flowing process, the filtering operation of the molten plastic is also realized, and the existence of plastic particles in the mixture is effectively reduced.

Description

technical field [0001] The invention relates to the field of equipment related to the production of modified plastics, in particular to a liquid curtain premixer for the production of toughened modified plastics. Background technique [0002] Modified plastics refer to plastic products that are processed and modified on the basis of general-purpose plastics and engineering plastics through filling, blending, reinforcement, etc., and have improved properties such as flame retardancy, strength, impact resistance, and toughness. The basic technologies include: 1. Reinforcement: blending glass fibers etc. with plastics to increase the mechanical strength of the plastics. 2. Filling: blend minerals and other fillers with plastics to change the shrinkage, hardness, strength and other properties of plastics. 3. Toughening: By adding a toughening agent to ordinary plastics and blending to improve the toughness of plastics. 4. Flame retardant: adding flame retardant to ordinary pla...
