The present invention relates to a resin composition, and more particularly to a resin composition in which a filler is uniformly dispersed in a thermoplastic resin and has excellent impact strength, weld strength, etc. Resin compositions in which synthetic resins are blended with inorganic fillers such as calcium carbonate, talc, and mica, or organic fillers such as wood flour and carbon black have been known, and have been widely used for various purposes. There is. These fillers are usually added to improve mechanical properties, etc. However, when spherical or irregularly shaped fillers such as calcium carbonate and precipitated barium have large particle sizes, they can cause concentration of external forces in the resin composition. In addition, if the particle size is too small, it tends to agglomerate, resulting in the same result as when using a large particle size, and the particle size is limited. Also, talc,
Flat materials such as mica cause a decrease in the impact strength and weld strength of the composition due to their shape, and furthermore, the shape is easily destroyed during kneading, resulting in a non-uniform composition. Therefore, the present inventors have worked hard to develop a resin composition that has no restrictions on the particle size, shape, etc. of the filler added to the thermoplastic resin, has good dispersibility, and has excellent mechanical properties. As a result of investigation, it was discovered that a resin composition containing a filler surface-treated with a specific glass can achieve the desired effect, and the present invention was completed. That is, the present invention contains phosphorus pentoxide (P 2 O 5 ), boron oxide (B 2 O 3 ), and M 2 O (where M represents an alkali metal) in amounts of 40 to 55 mol % and 6 mol %, respectively.
This is a resin composition in which a thermoplastic resin is blended with a filler surface-treated with a water-soluble glass containing 9 mol % and 30 to 60 mol %. The thermoplastic resin used in the present invention is not particularly limited, and various types can be used. For example, polyethylene, polypropylene, acrylonitrile-
Butadiene-styrene resin (ABS resin), polyamide resins such as nylon-6 and nylon-6,6, polystyrene, polyether, polyesters such as polyethylene terephthalate and polybutylene terephthalate, polycarbonate, polyvinyl chloride, polyether sulfone, polymethyl Examples include methacrylate, polyoxymethylene, polysulfone, polyphenylene oxide, and synthetic rubber. The resin composition of the present invention contains a filler whose surface has been treated with water-soluble glass. Here, water-soluble glasses include phosphorus pentoxide (P 2 O 5 ) and boron oxide (B 2 O 5 ).
O 3 ) and an alkali metal oxide (M 2 O, where M represents an alkali metal) are used. In particular, the molar ratio of each is P 2 O 5 /B 2 O 3 /
M2O =40-55/6-9/30-60 is used. In addition, examples of fillers include calcium carbonate,
Examples include inorganic fillers such as talc, mica, precipitated barium sulfate, glass fiber, silica, glass beads, and metal powder, and organic fillers such as wood powder such as poplar, fir, maple, and oak, and carbon black. These can be used alone or in combination. The particle size of these fillers is usually about 0.5 to 30 microns for inorganic fillers and 325 to 60 mesh for organic fillers. In the present invention, various methods can be applied to treat the surface of the filler with water-soluble glass, but usually the filler and the glass are mixed and the surface of the filler is treated with glass. A method of coating is preferred. The coating method can be carried out by adding a filler to an aqueous solution of water-soluble glass and heating and mixing to evaporate water. The processing conditions at this time vary depending on the water-soluble glass, filler, etc. used, but it is usually carried out by stirring at a temperature of 120 to 170°C for 10 to 20 minutes. The glass may be added in an amount of 1 to 20% by weight, preferably 2 to 15% by weight, based on the filler. When the filler whose surface has been treated with glass thus obtained is kneaded with a thermoplastic resin, it prevents the fillers from agglomerating together and enables uniform dispersion regardless of the particle size, shape, etc. of the filler. The amount of the filler surface-treated with water-soluble glass is not particularly limited and may be determined taking into consideration the intended use of the resin composition, but is usually 10 to 60% by weight. A titanate coupling agent may be added to the resin composition of the present invention if necessary. By adding a titanate coupling agent, the adhesion between the glass component and the filler component is improved, and the surface treatment effect of the filler by the glass becomes even more remarkable. In the present invention, each component is kneaded by a conventional method, for example, using a kneading machine such as a Banbury mixer, a single-screw extruder, or a twin-screw extruder.
As kneading conditions, for example, when using an extruder,
When using a Banbury mixer, the temperature is 190-230°C for 10-20 minutes. Next, the resin composition obtained in this way is pelletized, and the pellets are further subjected to injection molding,
Various molded products can be manufactured by molding into appropriate shapes using molding means such as extrusion molding. Since the resin composition of the present invention uses a filler whose surface has been treated with glass, the filler is prevented from aggregating and is uniformly dispersed without being affected by the particle size, shape, etc. of the filler used. Therefore, by using this resin composition, a molded article with extremely excellent impact strength can be obtained. In addition, destruction during kneading of the filler is prevented, and a decrease in the mechanical strength of the molded article due to its shape, particularly in weld strength, is also prevented.
Furthermore, since the resin composition of the present invention uses a specific filler as described above, it not only has improved rigidity, hardness, heat resistance, etc. due to the glass, but also has very excellent chemical resistance. Moreover, the molding shrinkage rate during molding is also small. Therefore, the resin composition of the present invention can be used for precision industrial parts,
It can be effectively used as a material for building materials, office equipment housings, audio parts, automobile parts, etc. Next, the present invention will be explained in detail with reference to Examples. Example 1 30 parts by weight of calcium carbonate was added to water-soluble glass (41.2% by weight of P 2 O 5 , 39.3% by weight of Na 2 O, K 2 O
12.5% by weight, B 2 O 5 7.0% by weight) 2 parts by weight 10
It was added to a weight percent aqueous solution and heated and mixed at 150° C. for about 10 minutes using a Henschel mixer to evaporate as much water as possible to obtain water-soluble glass-coated calcium carbonate. 70 parts by weight of homopolypropylene (manufactured by Idemitsu Petrochemical Co., Ltd., "J-700G") was added to the obtained water-soluble glass-coated calcium carbonate to form a gel, and the mixture was kneaded at 200°C in a single-screw extruder to form pellets. . Next, the chemical resistance and mechanical properties of test pieces (dimensions: 80 x 80 x 3.2 mm) obtained by injection molding the pellets were evaluated. The results are shown in Tables 1 and 2. In addition, chemical resistance and physical properties were evaluated as follows. Evaluation Method 1 Chemical Resistance A test piece was immersed in each of a 10% hydrochloric acid aqueous solution and a 5% acetic acid aqueous solution, and after boiling at 70° C. for 1 hour, the presence or absence of elution was evaluated. 2 Mechanical properties (1) Tensile strength Conforms to ASTM D-638 (2) Flexural modulus Conforms to ASTM D-790 (3) Izod impact strength Conforms to ASTM D-256 (4) Rockwell hardness Conforms to ASTM D-785 Compliant (5) Heat distortion temperature Compliant with ASTM D-648 (6) Weld retention Comparison of the presence or absence of welds based on tensile strength (7) Dispersibility A film with a thickness of 100μ was press-molded, and light transmission was visually judged. . ○...Good dispersion △...Slightly poor ×...Poor Example 2 In Example 1, the water content of the water-soluble glass was 80%
A test piece was obtained in the same manner as in Example 1, except that 0.3 parts by weight of a titanate coupling agent was added at the time of evaporation. Table 2 shows the physical property measurement results for this test piece. Examples 3 to 12 and Comparative Examples 1 to 11 Test pieces were obtained in the same manner as in Example 1, except that the types and amounts of each component were set to the proportions shown in Table 2. The measurement results for this test piece are shown in Tables 1 and 2.
