Definitions
- the present invention relates to a heat-resistant resin and a method for manufacturing the same, and more particularly, a heat-resistant resin having a high water content and a fine content, and a cohesiveness with a low water content, even if the heat resistance is equivalent or higher than that of the prior art, and a method for preparing the same. It relates to a heat resistant resin composition.
- the resin having excellent heat resistance as described above is prepared in the form of powder or pellets after obtaining a latex through emulsion polymerization and then undergoing a coagulation step, a dehydration step, and a drying step.
- the prepared latex has a problem that the glass transition temperature is very high, so that the aggregation is not easy, and the water content is very high (50% or more).
- the agglomeration of the latex may be performed by breaking up the latex particles stabilized by the emulsifier applied during the emulsion polymerization, by breaking the stability of the latex particles by a chemical method using various flocculants or by using a mechanical force by applying a strong shearing force.
- the chemical method breaks the stability by using different coagulants depending on the type of emulsifier used to ensure the stability of the latex
- the mechanical method applies a strong shear force to the latex to overcome the repulsive force between the emulsifier and the latex particles and particles To do that.
- a rapid coagulation process has been proposed as the chemical coagulation method.
- an excessive amount of flocculant aqueous solution such as an inorganic salt and an acid is added to break the stability of the emulsifier, thereby rapidly agglomerating the polymer in the latex.
- the agglomeration of the polymer particles of latex is called coagulation
- the agglomeration of the polymer particles is called a slurry, and since they are physically weakly bound, they are easily crushed by an external shear force by an agitator. break-up phenomenon. Therefore, the first aggregated slurry is subjected to an aging process, which is a process of increasing the binding force by mutual penetration between chains by raising the temperature.
- the slurry thus produced is finally dehydrated and dried to obtain a powder form.
- the latex stability is broken very quickly, so that the process of gluing the polymer latex particles occurs very quickly and disorderly. Due to such disordered aggregation, the apparent specific gravity is lowered, and the particle size distribution of the final particles is very wide.
- a slow coagulation process has been proposed to improve the powder characteristics of the final particles produced by controlling the coagulation rate through split dosing of coagulant. Since aggregation occurs in the secondary well region in which the energy barrier is present, the aggregation rate is slow and there is a possibility of rearrangement of the particles, so that spherical particles can be produced by regular filling.
- the overall amount of flocculant used is similar to that of rapid flocculation, and is merely a method of flocculation by performing split injection.
