始にともないえキナ−のモーター負狗が低下し始める。However, these vinyl chloride polymers with a high degree of polymerization also have the disadvantage of poor processability. This processability-improved flat film includes the addition of processing aids, a blend of low-polymerization vinyl chloride-based monomers, and internal aJ of vinyl chloride polymers.
Methods such as plasticization have been attempted, but among these methods, the method of adding processing aids not only increases costs, but also
It has disadvantages such as a decrease in rubber elasticity and temperature characteristics, and the method of internal plasticization also has disadvantages in a decrease in physical properties and an increase in cost, so it cannot be said to be a desirable improvement method. On the other hand, the method of blending a vinyl chloride polymer with a low degree of polymerization is achieved by appropriately setting the degree of polymerization and blending ratio, without impairing the characteristics of the main polymer. , it has the characteristic of achieving a significant improvement in workability. Therefore, for the purpose of improving the processability of vinyl chloride polymers with a high degree of polymerization, a method of blending low-power vinyl chloride polymers is extremely important. When manufacturing a product, it is necessary to go through a dry-up process prior to molding. That is, vinyl chloride resin, NJ! 11 agents, stabilizers, stabilizing a
JIFII, filler, modifier, etc. are put in, heated and offshore to absorb the liquid alkaline and stabilizer into the vinyl chloride resin, changing the initial wet state to a dry state. However, when the above-mentioned mixture is heated and stirred while gradually raising the temperature, this dry-up starts rapidly at a certain temperature, and with the start of this dry-up, the motor strength of the kina decreases. start.

の製造にとってきわめて1要な要素とされるのである。As the dry-up progresses, the motor load decreases, and when the dry-up is completed, the motor load becomes constant at the minimum load. During this time, the humidity inside the mixer continues to rise, but if the temperature is further increased even after drying is completed, t
The composition within the kitty begins to melt and the motor load increases again. Therefore, the soft compounding of vinyl chloride resin is usually completed between the completion of this dry-up and the melting start temperature, and the ending humidity varies depending on the degree of polymerization of the vinyl chloride resin and the amount of plasticizer added, but generally In the case of general-purpose vinyl chloride resin, this end temperature is 90 to 120°C;
AT combined seismic intensity is 120 to 180°C in the case of vinyl chloride resin, and the latter is 20 to 30°C higher than the former. The dried-up composition is cooled via a cooling mixer, or is subjected to a processing machine such as a roll extrusion type without being cooled. This dry-up composition is called a dry compound or powder powder, and it has a great effect on the processability and quality in the next processing step. It is considered to be an extremely important element.

た粉末状Htl物を得ることができなくなる。As mentioned above, the quality of soft vinyl chloride resin molded products is seriously affected by the quality of dry-up.
Dry-up in a mixture of a high polymerization degree vinyl chloride polymer and a low polymerization degree vinyl chloride polymer 2 is as follows:
As the degree of polymerization increases, the absorption capacity of C11FII increases, but the absorption rate decreases. Therefore, the low polymerization degree vinyl chloride polymer with a fast absorption rate absorbs the plasticizer first, and Plasticizers that should be absorbed by vinyl chloride polymers are also absorbed. This causes an imbalance in the amount of plasticizer absorbed between the two. On the other hand, since the plasticizer absorption capacity of low polymerization degree vinyl chloride polymer is smaller, the plasticizer absorbed by the low polymerization degree vinyl chloride polymer reaches saturation at a certain temperature, and the plasticizer that was not completely absorbed reaches saturation. The agent remains wet on the surface of the vinyl chloride polymer particles. As the temperature is further raised, the excess plasticizer is gradually absorbed into the vinyl chloride resin with a high degree of polymerization, but at the same time, the low degree of polymerization vinyl chloride polymer that has reached saturation begins to melt, resulting in one composition. The entire product becomes sticky, and it becomes impossible to obtain a dry powdery Htl product, which is the purpose of drying up.

えられる。According to the method of the present invention, the plasticizer is completely absorbed into the particles of the vinyl chloride polymer of both low polymerization degree and high polymerization degree carbon, so it is well penetrated into the extruder. , the elasticity is greatly improved; ■ Because the plasticizer is uniformly contained within the polymer particles, melting in the molding machine becomes uniform, eliminating unevenness and roughness on the surface of the molded product; ■ Polymerization This eliminates the imbalance in the amount of plasticizer absorbed by the vinyl chloride polymer, which often occurs when molding, so there is no fish eye formation.■ Melting in the molding machine is uniform from low to high temperatures, which increases the processing time. This gives you the advantages of being able to

Although it is common practice to mix and absorb the vinyl chloride carbonate polymer into the respective vinyl chloride carbonate polymers, this means that it is mixed and absorbed into the vinyl chloride polymer having a high degree of polymerization. In other words, this a means that the weight ratio of the amount of plasticizer blended into the high polymerization degree vinyl chloride polymer and the amount of plasticizer blended into the low polymerization degree vinyl chloride polymer is the same as that of the high polymerization degree vinyl chloride polymer. 'WJII' so that the weight ratio is greater than the weight ratio of the amount and the amount of low polymerization vinyl chloride 1 unit.
It is best to combine these agents to achieve excellent results.

ていく。The dry-up operation is carried out using a high overvoltage mixer (Henv Elmikichy, Super Mixer, etc.) or a ribbon blender as a mixer, but the order in which the vinyl chloride polymer, stabilizer, and stabilizing aid are added is Agents, pigments, etc. may be added at the same time from the beginning, and plasticizers and fillers may be added separately as necessary. The temperature inside the mixing chamber is gradually raised by heat generated by the rotation of the mixer blades, heating by the external jacket, etc.

よい場合がある。前記αはそのための調整量である。The amount of plasticizer added in each of the dry-up steps described above is such that for low polymerization degree vinyl chloride polymers, the maximum absorption capacity of plasticizer 1 is 100 to 120 parts by weight per 100 parts by weight of the polymer; For vinyl chloride polymers, it is 1.
! It is large, more than i0 irises. For this reason, if necessary, it may be better to reduce the yield of plasticized material to the low degree of polymerization vinyl chloride polymer to be equal to or less than the blend ratio (X, Y) of the vinyl chloride polymer. The above α is an adjustment amount for that purpose.

Taking advantage of this property, if the blend of a low polymerization degree vinyl chloride polymer is sticky, it may be better to increase the blending amount of the filler to the blend ratio of the vinyl chloride polymer.
