Definitions
- the present study relates to a hard-to-refractory resin composition that does not generate harmful gas during combustion, has little residual ash after incineration, and has excellent mechanical strength.
- the conventional polyolefin-based flame-retardant resin composition is composed of a polyolefin-based resin mixed with magnesium hydroxide or aluminum hydroxide, and crystallized with magnesium hydroxide or aluminum hydroxide power of 200 to 350 ° C.
- a polyolefin-based resin mixed with magnesium hydroxide or aluminum hydroxide, and crystallized with magnesium hydroxide or aluminum hydroxide power of 200 to 350 ° C.
- the surface of melaminocyanurate is treated with a nonionic surfactant of HLB 1 to 8 and used together with the phosphorus compound.
- a method of imparting flame retardancy without reducing the mechanical strength of the polyolefin resin has been proposed (JP-A-6-157820).
- this method of treating the surface with a surfactant has been proposed.
- it has the effect of improving the affinity between melamininate and the resin, it occurs because the molecular weight of the surfactant dispersed on the surface of the resin is relatively small.
- the degree of the mobile diffusion phenomenon was large, and the product appearance was deteriorated by bleeding on the resin surface. Therefore, attempts were made to reduce the amount of surfactant in order to minimize the resin surface pread.However, the affinity with the resin was reduced, and the mechanical strength and flame retardancy of the resin were reduced. The improvement was limited.
- An object of the present invention is to provide a flame-retardant resin composition which does not generate harmful gas during combustion, has little residual ash after incineration, and has excellent mechanical strength.
- Melamine cyanurate has good flame retardancy, but has poor affinity for polyolefin-based resin and poor dispersion in the resin, which lowers the mechanical strength of the resin. Get sufficient flame retardancy There was a problem that it was not possible to mix only the amount. The present inventors have conducted intensive studies on these problems, and as a result, it has been found that the mechanical strength of the composition decreases with increasing the amount of melaminocyanurate alone that has been surface-treated with fine powdered silica. In addition, polyester phosphate additionally reduced the mechanical strength and improved the flame retardancy, and completed the present invention, that is, polyolefin.
- the polyolefin resin used in the present invention is not particularly limited, and it includes, but is not limited to, an olefin polymer such as polyethylene and polypropylene, ethylene and or olefin, vinyl acetate, and acrylic resin. Examples thereof include copolymers of phosphoric acid, acrylic acid ester, methacrylic acid, and methacrylic acid ester. These resins are used alone or in combination of two or more.
- the melamine cyanurate which has been surface-treated with the fine powder silica used in the present invention is mixed with a suitable mixer, for example, a hensyl mixer, using the melamine cyanurate powder and the fine powder silica.
- a suitable mixer for example, a hensyl mixer
- the silica is preferably a finely divided silica having an average particle size of 10 m or less.
- a commercially available melamininate that has been surface-treated with colloidal silica can be used.
- the acid ester used in the present invention is not particularly limited, but may be any of triphenyl phosphate, triglycidyl phosphate, polyphosphate compound, and resorcinol polyphosphate. Compounds, trixylenyl phosphate and triaryl phosphate.
- the polyolefin resin In the flame-retardant resin composition of the present invention, the polyolefin resin
- Melamine cyanurate surface-treated with fine powder silicide is blended in an amount of 2 to 60 parts by weight and phosphate ester in an amount of 1 to 30 parts by weight based on 100 parts by weight.
- the blending ratio of the melaminocyanurate exceeds 60 parts by weight, the mechanical strength of the polyolefin resin composition is significantly reduced, and when it is less than 2 parts by weight, the effect of flame retardancy cannot be expected. No.
- the proportion of the phosphate ester exceeds 30 parts by weight, poor dispersion occurs, and when the proportion is less than 1 part by weight, the effect of improving the flame retardancy and mechanical strength of the polyolefin resin composition becomes insufficient. .
- the flame-retardant resin composition of the present invention obtained as described above has excellent flame retardancy and mechanical properties due to the synergistic effect brought about by the addition of both the surface-treated melaminate and the calcined ester. It has the same target strength. That is, since the moldability is good and the appearance of the product is good, it can be processed into various industrially used forms such as a hollow molded article, a plate, a sheet, or a film. In addition, since it does not have halogen compounds, it does not emit harmful gases and burns down after use or incineration, and there is little residual ash, so there is no special cost for treating it.
- Ethylene vinyl acetate copolymer (Sumitomo Chemical Co., Ltd. H 2020) 100 parts by weight of colloidal silica-treated melanin cyanurate (Nissan Chemical Co., Ltd. MC-440) And aromatic phosphoric acid Ester oligomer (CR-733S, manufactured by Daihachi Chemical Industry Co., Ltd.) was dry blended at the compounding amount shown in Table 1, and a compound was prepared using a twin-screw extruder. Using this compound as is, the processing temperature
- Table 1 shows the formability, elongation at break, oxygen index, and results of the Fire and Disaster Management Agency test conducted by the Fire and Disaster Management Agency of the Ministry of Home Affairs for the obtained sheet.
- Ethylene-propylene random copolymer (E-401E, manufactured by Tonen Chemical Co., Ltd.) 100 parts by weight of melaminocyanurate surface-treated with colloidal silica (Nissan Chemical Industries, Ltd.) MC-440) and ammonium polyphosphate (Smithif P, manufactured by Sumitomo Chemical Co., Ltd.) were dry blended in the amounts shown in Table 1, and the sheets were prepared in the same manner as in Examples 1-3. Was fabricated and performance was evaluated. The results are shown in Table 1.
- Ethylene vinyl acetate copolymer (Sumitomo Chemical Co., Ltd. H 2020) Dry blending of 20 parts by weight of Melaminurinate (MC-440 manufactured by Nissan Chemical Industries, Ltd.), which was surface-treated with colloidal silicide, to 100 parts by weight, as in Examples 1 to 3 Then, a sheet was prepared and its performance was evaluated. The results are shown in Table 2.
- the breaking strength was measured in accordance with JISZ1702.
- the elongation at break was measured according to JIS Z1702.
- the oxygen index was measured according to JISK 7201.
- the flame-retardant polyolefm-based resin composition of the present invention has excellent flame retardancy due to the synergistic action of the surface-treated melaminocyanurate and oxalate. It has an improvement effect on mechanical strength.
- the resin composition of the present invention since the resin composition of the present invention has good moldability and good product appearance, it can be processed into various industrially used forms such as a hollow molded article, a plate, a sheet, and a film.
- this resin composition does not contain halogen compounds, so it does not generate harmful gases even when burned or incinerated after use, and has little residual ash, so there is no special cost for treating it.
- Environmental pollution prevention From the standpoint of this, there is a highly public effect.
