Problems solved by technology

Therefore, the moldability of the resin tends to deteriorate, and the mechanical strength of the resulting molded product, etc. tends to decrease, thus causing a problem that the application of usable resin-processed products, etc., is limited.
In addition, molded articles made of triazine-based flame retardants are often glossy, so the design of molded articles is limited
The gloss of molded products can be removed by blending matting agents such as talc or calcium carbonate, but there are still problems of poor toughness and flame retardancy of molded products
In addition, although red phosphorus has a high flame retardant effect, due to insufficient dispersion, red phosphorus tends to inhibit electrical properties, generate harmful gases, reduce moldability and cause bleeding

Embodiment 1

[0141]In a side-flow type twin-screw extruder (manufactured by The Japan Steel Works, LTD.), the following components were mixed and kneaded at 280° C. to obtain resin pellets: 55.5 parts by mass as thermoplastic resin Nylon-66 (produced by Ube Industries, Ltd.: 2020B), glass fibers of 25 parts by mass as reinforcing fibers, which were each surface-treated with a silane coupling agent, and each fiber length was about 3 mm (ASAHIFIBER GLASS Co. , Ltd. production: 03.JAFT2Ak25), 0.2 mass parts of carbon black as a colorant, 0.3 mass parts of an antioxidant (Chiba Specialty Chemicals Co., Ltd. production: Irganox 1010), 5 mass parts of an inorganic filler Particle diameter is the talc of 2 microns, the compound of formula (I-2) as 10 mass parts of metal phosphinate, and the compound of formula (II-3) of 4 mass parts as active organic phosphorus flame retardant compound. The pellets were dried at 115°C for 4 hours, and then molded using an injection molding machine (manufactured ...

Embodiment 2

[0143] The resin-treated article of Example 2 was prepared in the same manner as in Example 1, except that, in Example 1, Nylon-66 (produced by Ube Industries, Ltd.: 2020B) was used as the thermoplastic resin The addition amount of the compound was changed to 51.5 parts by mass, and 4 parts by mass of nanoparticle-sized clay (manufactured by Volclay Japan, Co.: Nanomer I30T) was newly added.

Embodiment 3

[0145] The resin-treated product of Example 3 was prepared in the same manner as in Example 1, except that, in Example 1, Nylon-66 (produced by Ube Industries, Ltd.: 2020B) as a thermoplastic resin Add-on becomes 51.5 mass parts, replaces the compound of formula (I-2) with the compound of formula (I-5) of 10 mass parts and adds as metal phosphinate, with the compound of formula (II-1) of 4 mass parts Instead of the compound of formula (II-3) added as an active organic phosphorus flame retardant, 4 parts by mass of an organic phosphorus-based flame retardant represented by the following structural formula (A) was newly added.

Abstract

An article treated with a flame retardant resin that has excellent flame retardancy without bleeding. There is provided a resin composition in a molded form or in a coating form, the composition comprising a metal phosphinate flame retardant represented by the general formula (I) (wherein R1 and R2 each independently represent a C1-6 alkyl group, or Aryl containing equal to or less than 12 carbon atoms; wherein M represents calcium, aluminium or zinc; when M=aluminum, m=3, in other cases m=2), terminally unsaturated reactive organic In the phosphorus flame retardant and resin, the total amount of the metal phosphinate and the active organic phosphorus flame retardant is 5-30% by mass.

Description

technical field [0001] The present invention relates to an article treated with a flame-retardant resin for use in, for example, electric parts and electronic parts, as a resin-molded article, a coating film or a sealant. More specifically, the present invention relates to halogen-free, non-halogen-based flame retardants. Background technique [0002] Thermoplastic resins such as polyesters and polyamides and thermosetting resins such as epoxy resins each have excellent moldability, mechanical strength and electrical characteristics for general-purpose resins and engineering plastics, and thus have been used in various fields including electricity and electronics. field. In addition, resin materials made by processing and molding these resins are required to be flame-retardant in view of safety against high-temperature ignition. For example, specifications such as UL94 have been provided as a rating for flame retardancy. [0003] Halogen species are generally known to be ...
