preparation example 1

[0076] Preparation Example 1: Preparation of PPS

[0077] 40 kg of p-diiodobenzene, 3.4 kg of sulfur and 150 g of 1,3-diiodo-4-nitrobenzene as a catalyst were melt blended in a reactor at 180°C. The mixed reactants were polymerized while increasing the temperature from 180°C to 340°C and decreasing the pressure from 350 Torr to 10 Torr. 5 hours after the start of the polymerization, 150 g of sulfur and 100 g of diphenyl sulfide as a polymerization terminator were added to the reaction mixture, and the polymerization reaction was further carried out for 3 hours to obtain a polymer.

[0078] The melt viscosity (MV), melting point (Tm) and weight ratio of the repeating unit of the resulting PPS polymer were determined according to the following methods. The results showed that the MV of the PPS polymer was 2000 poise, the Tm was 280°C, the number average molecular weight was 16,400, and the weight ratio of the arylene sulfide unit to the arylene disulfide unit was 1:0.003.

Embodiment 1

[0085] Embodiment 1: the preparation of PPS resin composition

[0086] With 67% (weight) of PPS resin obtained in Preparation Example 1, 15% (weight) of epoxy silane (OCV-910, Owens Corning) process glass fiber, 8% (weight) of elastomer (Lotader AX- 8900, Arkema), 5% (weight) of phenoxy resin (YP-50, Kukdo Chemical company) and 5% (weight) of white pigment TiO 2 (Grade 2233, Kronoss) was fed into a twin screw extruder to prepare the composition.

[0087] The diameter of the extruder is 40mm, L / D is 44 (SM Platek). The extrusion conditions were a screw speed of 250 rpm, a feed rate of 60 kg / hour, a barrel temperature of 280-300° C. and a torque of 60%. The above materials are fed through three feeders in total, among which the first feeder is used to feed PPS resin, elastomer and phenoxy resin, the second feeder is used to feed white pigment, and the third feeder The device is used to feed glass fiber.

Embodiment 2-7

[0089] Repeat the same steps as in Example 1 to prepare the PPS resin composition, except that the components and their amounts are shown in Table 2 below.

Abstract

The present invention relates to a polyarylene sulfide resin composition with a low out-gas content. The composition comprises a polyarylene sulfide and a phenoxy resin. The polyarylene sulfide resin composition of the present invention exhibits a low out-gas content and excellent tensile strength and metal adhesive strength, and therefore the composition can be useful as a resin composition for preparing a product requiring molding precision.

Description

technical field [0001] The present application relates to a polyarylene sulfide composition, which has excellent tensile strength and metal bonding strength, and a small outgassing amount. Background technique [0002] Polyarylene sulfide (PAS) is currently a representative engineering plastic, and due to its high heat resistance, chemical resistance, flame resistance and electrical insulation, it is used in electronic products used in high temperature and corrosive environments increased demand in . [0003] Polyphenylene sulfide (hereinafter referred to as "PPS") is the only commercially available polyarylene sulfide. Due to its excellent mechanical, electrical, and thermal properties, as well as chemical resistance, PPS is widely used in housings or main components of automotive equipment and electrical or electronic equipment. [0004] The main method used for the commercial production of PPS is the Macallum method, which produces PPS by solution polymerization of p-di...
