Description

A kind of tandem rubber continuous mixing method

Technical field:

The invention belongs to the technical field of processing methods for rubber molding, and relates to a serial rubber continuous mixing method, which is applicable to the mixing of rubbers with different formulas.

Background technique:

The rubber industry is one of the important basic industries of the national economy. It not only provides people with daily and medical light industrial rubber products that are indispensable in daily life, but also provides heavy and emerging industries such as mining, transportation, construction, machinery, and electronics. All kinds of rubber production equipment or rubber parts, and the quality of mixing technology has a decisive effect on the quality of rubber processed products. Therefore, the production of low energy consumption, high efficiency and high quality rubber is a problem that the rubber industry must constantly solve. At present, rubber mixing methods can be roughly divided into open mill mixing and internal mixer mixing. Both of these two mixing methods belong to batch mixing technology, which has the following disadvantages: continuous parking, unloading, Loading, low production efficiency and high energy consumption; the two types of equipment are bulky and occupy a large area; the pressure and temperature on each part of the rubber material during the mixing process are not uniform, resulting in large differences in rubber properties, which ultimately affect The quality of the finished product; the waste of compounding agents is serious, and the environmental pollution is relatively large.

In comparison, continuous mixing technology has the following advantages: it can make full use of the advantages of mixing itself to realize continuous production to improve production efficiency; during the mixing process, it can ensure that the pressure, temperature, and mixing The time is the same to improve the quality of rubber; the degree of automation is high, and the rubber can be mixed under stable process conditions, which reduces the consumption of manpower and material resources; the equipment is closely coordinated with each other, the floor area is small, and the investment cost is low. For example, Chinese patent 200910229437.1 discloses a method of rubber mixing, which first mixes the compounding ingredients evenly, and puts super-accelerator and vulcanizing agent into the internal mixer to realize rubber mixing in one step; this method can reduce flying dust, Moreover, the premixed compounding agent and raw rubber are easy to be compatible and have good dispersibility, which shortens the mixing time, reduces the power consumption of mixing, and is beneficial to prevent scorching. However, the above-mentioned method is not highly automated. Mixing is also difficult to achieve the standard of uniformity, and it is easy to cause deviations in the performance of the rubber compound; Chinese patent 200580035588.3 discloses a rubber mixing device and mixing method, which utilizes serial mixing technology to combine the internal mixer and the open mixing unit It becomes a mixing line, and the pre-mixed rubber mixed by the closed mixer is selectively supplied to the parallel mixing line through the distribution conveyor belt. Although this mixing technology improves the mixing efficiency, it is not suitable for constant temperature. For mixing and low-temperature mixing, it is impossible to guarantee the temperature that needs to be kept constant during mixing, and at the same time it will cause energy loss and increase costs; therefore, continuous mixing with a high degree of automation in the true sense can be achieved while ensuring rubber properties Quality is the research direction of this invention.
