Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, based on the examples herein, which are within the scope of the application as defined by the claims, will be within the scope of the application as defined by the claims.
Hereinafter, embodiments will be described with reference to the drawings. Furthermore, the embodiments shown below do not limit the summary of the application described in the claims. The whole contents of the constitution shown in the following examples are not limited to the solution of the application described in the claims.
Referring to fig. 1 to 5, the present embodiment provides a kneading method for producing a carbon fiber heat insulating material using a kneader. The kneader is an ideal apparatus for kneading, vulcanizing and polymerizing high-viscosity, elastoplastic materials. The kneader is a special mixing stirring device, and most commonly adopts two sigma paddles, adopts side by side tangent differential arrangement, namely, the speed of one stirring paddle is high, the speed of the other stirring paddle is low so as to generate shearing force, and the different paddle speeds enable the mixed materials to be sheared rapidly, so that the materials can be mixed uniformly. The kneader may be heated up and evacuated. Wherein the kneader may be a NHZ-1000 kneader.
Firstly, raw materials for producing the carbon fiber heat insulation material are weighed, and the weighed raw materials are placed beside a kneader for standby. And putting the weighed raw materials into a kneader and starting the kneader to carry out mixing. And stopping the kneader after the mixing is completed, discharging and storing.
The mixing amount of the kneader is far larger than that of an open mill, such as a NHZ-1000 kneader with respect to the dimensional space of a 14-inch open mill, the maximum mixing amount of the 14-inch open mill is 7kg, and the maximum mixing amount of the NHZ-1000 kneader is 600kg. Although the single mixing time of the NHZ-1000 kneader is longer than that of the open mill, the mixing efficiency of the kneader is higher than that of the open mill for a large demand of 600kg because the mixing amount of the kneader is much larger than that of the open mill. Therefore, the kneading by the kneader improves the kneading efficiency.
Specifically, according to the formula, the raw materials 110 are silicon rubber, carbon fiber, hollow glass beads and other filler density and expansibility, and the maximum rubber mixing amount of each batch of NHZ-1000 is 600kg by combining the operating volume of a NHZ-1000 kneader, according to the required heat insulation performance, mechanical strength, spraying technology and the like. Firstly weighing 250-300kg of 110 silicone rubber, placing 110 silicone rubber beside a kneader for standby, weighing 250-300kg of filler, and placing the filler beside the kneader for standby. Weighing for 0.5-1 hr. Wherein the 110 silicone rubber is 110 methyl vinyl silicone rubber, and the filler comprises carbon fiber filler, hollow glass bead filler and the like.
When mixing, firstly, the kneader is powered on, then the weighed 110 silicon rubber is sequentially put into the kneader, after the putting is finished, the kneader is started to rotate, and the proper rotation speed is adjusted to stir the put 110 silicon rubber uniformly. And then adding fillers such as carbon fibers, hollow glass beads and the like. After the filler is added, a kneader is started to carry out mixing for two hours, and the whole is 4-5 hours.
Firstly, 110 silicon rubber is added and stirred, and then fillers such as carbon fiber and hollow glass beads are added, so that the 110 silicon rubber is more uniformly mixed with the fillers such as carbon fiber and hollow glass beads.
In some embodiments, the filler such as carbon fiber, hollow glass beads, etc. is added 3-5 times. And after the fillers such as carbon fiber and hollow glass beads are added each time, firstly mixing for 5-10 minutes, and then adding the fillers such as carbon fiber and hollow glass beads for the next time. By the arrangement, the 110 silicon rubber is more uniformly mixed with the carbon fiber, the hollow glass bead and other fillers.
In other embodiments, after the filler is added, a filler surface treating agent, such as KH550, i.e. a silane coupling agent, also known as gamma-aminopropyl triethoxysilane, is a colorless transparent liquid, and can be used for coupling an organic polymer and an inorganic filler, enhancing the cohesiveness of the organic polymer and the inorganic filler, and improving the mechanical, water-resistant, anti-aging performance of the product. The filler surface treating agent is added for modifying the filler, so that the surface polarity of the filler such as carbon fiber, hollow glass beads and the like is weakened, the oil absorption value is lower, and the compatibility with nonpolar 110 silicon rubber is better, thereby relatively improving the addition amount of the filler and improving the mechanical property, high temperature resistance and heat insulation property of the material.
When the filler is completely added and mixed, the kneader is firstly regulated to be heated to 150 ℃ and kept at a constant temperature, and then the interior of the kneader is vacuumized. And then mixing, thus providing high temperature treatment and negative pressure environment, being capable of better removing moisture, micromolecule and other volatile substances in the 110 silicon rubber and the filler, providing higher surface energy of the sizing material, leading the compatibility to be better, leading the product to be more stable and being beneficial to the high temperature resistance and ablation resistance of the rear end product. Wherein, when the interior of the kneader is vacuumized, the vacuum degree is more than-0.1 MPa.
The heating and vacuumizing functions of the kneader can be utilized to effectively treat the surface of the carbon fiber material, so that the compatibility and the dispersibility of the carbon fiber in a matrix can be improved, and meanwhile, moisture and other low molecules in the material can be more fully removed at high temperature and in a vacuum state, which is beneficial to the heat insulation performance of the material.
It is worth noting that the whole 4-5 hours is calculated after the time of adding the filler excessively, adding the filler surface treating agent, heating up and evacuating.
After the rubber mixing is finished, stopping heating and vacuumizing, starting cooling and cooling to below 50 ℃ to discharge, and storing 600kg of mixed materials in a 200L stainless steel barrel for the next working procedure for 1.5-2 hours.
In general, 600kg of mixed materials can be produced in each batch of the kneader batch production process, the time is about 6-8H, the required labor is 2-3 people, the operation process is continuous operation under the condition of heating and reducing pressure, and the rubber mixing process is finished mechanically except for the manual operation in the feeding and discharging packaging stages, so that the labor intensity is low; the production process can continuously produce 1 batch per working day according to 8H working hours per working day, the daily productivity is 600kg, and the monthly productivity is 15600kg according to 26 working days per month.
For an open mill, according to the formula raw materials 110 silicon rubber, carbon fiber, hollow glass beads and other fillers density and expansibility, the maximum rubber mixing amount is 7kg in combination with the size space of the 14-inch open mill, according to the required heat insulation performance, mechanical strength, spraying technology and the like, 3-4kg110 silicon rubber is weighed and temporarily stored in a 5LPP white barrel, 2-3kg carbon fiber, hollow glass beads and other fillers are weighed and temporarily stored in the 5LPP white barrel, and the open mill is placed beside the open mill for standby, and the time is 0.5H.
When in rubber mixing, the open mill is powered on, the roll gap is adjusted, 110 silicone rubber is put between the two rolls at one time, the rolls start to be started, fillers such as carbon fibers, hollow glass beads and the like are added gradually in sections, the addition is generally divided into 5-6 times, the mixing is carried out for 10 minutes after each filler addition, the mixing is carried out for 0.5 hour after the filler addition, and the working period is 1.5 hours.
After the rubber mixing is completed, each batch of mixed materials is temporarily stored in a 20kg PP barrel for the next working procedure to be used, and the time is 0.5 hour.
In general, 7kg of mixed materials can be produced in each batch by the batch production process of the open mill, the time is about 2.5 hours, the required labor is 2-3 people, the operation process is continuous operation at normal temperature and normal pressure, and the whole process of batching, mixing, discharging and packaging is manually operated, so that the labor time of operators is long, and the labor intensity is high; three batches can be produced in batches per working day according to the working hour of 8 hours per working day, namely, the daily productivity is 21kg, and the monthly productivity is 546kg calculated according to 26 working days per month.
