- an epoxy resin a bisphenol A type epoxy resin having an epoxy equivalent of about 43 g/mol was prepared.
- glass fibers having a diameter of 9 to 16 ⁇ m and surface-treated with trimethoxysilane were prepared.
- a PPS composite resin was prepared by mixing the PPS resin, the olefin-based elastomer, the epoxy resin, and the inorganic filler in contents shown in Table 1 below.
- Example 2 Using the same composition as in Example 1, but varying the content as shown in Tables 1 and 2 below, PPS composite resins were prepared, and Examples 2 to 5 and Comparative Examples 1 to 8 were performed, respectively.
- a PPS composite resin was prepared in the same manner as in Example 1, but poly(methylene-co-glycidyl methacrylate) was used as an olefin-based elastomer.
- a PPS composite resin was prepared in the same manner as in Example 1, but ethylene-1-octene copolymer was used as an olefin-based elastomer.
- V-notched charpy V-notched charpy
- Epoxy bond strength and epoxy bond failure behavior were measured by preparing an ASTM tensile test piece with a PPS composite resin molded body, then cutting the test piece in half and attaching an epoxy adhesive (manufacturer: ESP CHEMICAL IND. CO. LTD., product name: H) to one side of the cross section. After applying -560D & EC260 (D)), as shown in Figure 1, after overlapping by 5 mm, heat treatment at 80 ° C for 2 hours, heat treatment at 100 ° C for 4.5 hours, and then tensile the specimen at a rate of 2 mm / min measured. Then, the evaluation of epoxy bond failure behavior is as follows.
- the flowability (MFR) and extrusion productivity of the PPS composite resin were measured under the condition of 315°C and a load of 2.16 kg.
- the extrusion productivity was measured after extruding 1 ton or more of the PPS composite resin, and there were defects such as clogging of the nozzle and molding defects. It was determined whether or not it occurred.
- Comparative Example 8 using an excessive amount of inorganic filler at 73% by weight, compared to Example 1, the tensile strength and elongation were good, but the impact strength and adhesive strength were lowered, and flowability and extrusion productivity were poor. .
- the PPS composite resin of the present invention can provide a molded article, preferably an extrusion molded article, having excellent adhesiveness and mechanical properties while containing a high content of inorganic filler.
