Abstract
The invention discloses a method for mixing peroxide and polyolefin and equipment, and relates to the technical field of modified material processing technology. The mixing method comprises the following steps of: filling the polyolefin and the liquid peroxide in a plastic container and closing; putting the closed plastic container on the stirring equipment; and operating the stirring equipment to drive the closed plastic container to rotate, and reversely rotating the plastic container. The purpose of full mixing is fulfilled by driving the plastic container to rotate through a synchronous device in the equipment; and by the method, safe production of the plastic modification industry using the peroxide as an additive can be realized, and the stability of the product can be ensured.
Description
Technical field
The present invention relates to material modified technology field, be specifically related to the equipment of a kind of liquid peroxide and polyolefinic mixed method and use.
Background technology
In recent years, be additive with peroxide, add in polyolefin and form new material, occupy a tiny space in material modified field; Comprise cooling masterbatch, high fusion index film-coating material, cross-linked polyolefin, take peroxide as the thermoplastic elastomer (TPE) of initator, liquid peroxide all will be adopted in process of production to be main additive.
But liquid peroxide, because boiling point is low, volatilization fast, easily causes unstable product quality; More seriously, if adopt conventional mixed method, easily cause spontaneous combustion and blast, bring very large hidden danger to safety in production.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method of continuous, safe, stable peroxide and polyolefin mix and blend, and the method can make to be that the modifying plastics industrial security of additive is produced with peroxide, and can ensure the stability of product.
The present invention provides the equipment used when peroxide and polyolefin mix and blend simultaneously.
For achieving the above object, the invention adopts following technical scheme:
The method of described peroxide and polyolefin mixing, comprises and is contained in plastic containers by polyolefin and liquid peroxide, airtight step; Airtight plastic containers are placed in the step on mixing plant; Mixing plant action, drives airtight plastic containers to rotate, and the step that plastic containers are reversely rotated.
For better implementing the invention, described plastic containers rotary speed is 5-25 rev/min.
For better implementing the invention, the interval time of the forward and reverse rotation of described plastic containers is 5-10 minute.
For better implementing the invention, described plastic containers rotate 20-60 minute on mixing plant.
For better implementing the invention, described plastic containers volume is 10-50 liter.
Drive the mixing plant that airtight plastic containers rotate, comprise the power source, the deceleration device that are connected successively and realize the sychronisation of synchronized in the same way motion, the driving wheel of sychronisation is connected with reduction unit output shaft, and two turning cylinders are connected with the driving wheel of sychronisation and driven pulley respectively and realize synchronous axial system; And the distance between two turning cylinders is determined by adjustable fixed support in turning cylinder two ends.
Described mixing plant, described sychronisation is set to driving pulley, driven pulley, and two synchronous pulleys realize transmission by Timing Belt.
Described mixing plant, described turning cylinder is provided with the uneven projection of convex-concave.
Described mixing plant, described adjustable fixed support one end is provided with u shape hole.
Described mixing plant, described turning cylinder can carry out position and move in u shape hole.
Owing to have employed technique scheme, the present invention has following beneficial effect:
1, adopt plastic containers, avoid plastics and liquid peroxide when mixing in canister, easily produce the potential safety hazard of accumulation of static electricity and electric discharge, avoid the liquid peroxide burning and blast that to make after electrostatic produces to be easy to catch fire from source.
2, adopt closed container to ensure that liquid peroxide can not evaporate into outside stirred vessel, both ensure that safety in production, in turn ensure that the stable of product quality.
3, employing speed and turn to adjustable device, ensure that stirring fully and evenly, what make to utilize liquid peroxide to be additive material modifiedly can produce continuously, safely and steadly.
Accompanying drawing explanation
Fig. 1 is the structural representation of the airtight plastic containers of the present invention;
Fig. 2 is the structural representation of mixing plant of the present invention;
In figure: 1, plastic containers; 2, lid; 3, connecting thread; 4, drive motors; 5, reductor; 6, belt pulley; 7, belt; 8, turning cylinder a; 9, turning cylinder b; 10, adjustable fixed support.
Detailed description of the invention
Composition graphs 1, Fig. 2, during mixing, polyolefin and liquid peroxide are contained in 20 liters of Plastic Drums, then airtight good lid 2, screws particular by connecting thread 3, and liquid can not be leaked.The Plastic Drum installing mixture being placed between turning cylinder a8 and turning cylinder b9, regulating the distance of two between centers by rotating the position of axle b on adjustable fixed support 10 in u shape hole, regulate two between centers spacing to be 20 centimetres.Start drive motors 4, drive motors drives the pulley rotation of turning cylinder a through reductor 5, drives turning cylinder b9 to rotate with direction at the same rate when turning cylinder a8 rotates by belt 7.Because turning cylinder is provided with the uneven projection of convex-concave; add mantle friction; in the effect of frictional force, turning cylinder drives Plastic Drum to rotate, and the rotating speed of Plastic Drum is adjusted to 5 revs/min; rotate 10 minutes; then regulate in the opposite direction rotate 10 minutes, so changed every 10 minutes first power to, co-blended is after 40 minutes; the material mixed is added comminutor hopper, and mixed process terminates.
