Problems solved by technology

[0009] However, processed products using the flame-retardant resin composition disclosed in Patent Document 1 cannot satisfy the strength and bending resistance, and further improvement in physical properties is expected.
[0010] In addition, although a non-halogen-based resin composition that solves the problem of processed products using the flame-retardant resin composition disclosed in Patent Document 1 has also been proposed, there are problems in that the resin itself undergoes thermal yellowing or processing using the resin The thermal yellowing of the product will significantly reduce its designability. At the same time, the resin itself is yellowing or the processed product using the resin is very hard, and the bending resistance cannot be controlled (for example, refer to Patent Document 2)

Embodiment 1

[0052] 150 g of ion-exchanged water was put into a 1 L five-necked detachable flask, and heated to 80° C. while stirring. 36 g of ethyl acrylate, 36 g of methyl methacrylate, 18 g of acrylic acid, and 60 g of polyoxyethylene glycol monomethacrylic acid phosphate (manufactured by Kyoeisha Chemical Co., Ltd., Laitester P-1M, phosphorus content 15% by mass) , 1.5 g of sodium dodecylbenzenesulfonate, 7.5 g of polyoxyethylene alkyl ether, and 190 g of ion-exchanged water were uniformly emulsified. 0.2 g of potassium persulfate was added to the separable flask, and the reaction was started by starting the dripping of the monomer emulsion. While adding the monomer emulsion to the separable flask over 4 hours, 30 g of a 3% potassium persulfate aqueous solution was added over 4 hours. After completion of addition of the monomer emulsion, it was stirred at 80° C. for 1 hour to complete the reaction. The inside of the separable flask was cooled, and 8 g of a 30% aqueous sodium hydroxid...

Abstract

Disclosed is a resin composition, which is free from any halogen-based component with a risk of generating dioxins or hydrogen halides and can impart excellent strength, bending resistance, flame resistance and heat yellowing resistance to a processed paper or fiber product. Specifically disclosed is a resin composition obtained by copolymerizing an unsaturated monomer having a phosphate or phosphite group, an alkyl (meth)acrylate monomer and an unsaturated monomer having a carboxyl group, characterized by: having a definite phosphorus content in the solid components; and containing an alkyl (meth)acrylate monomer, wherein the alkyl chain has 1 to 4 carbon atoms, and an unsaturated monomer having a carboxyl group, each in a definite amount. A processed paper or fiber product, which has been treated with the aforesaid resin composition, has excellent strength, bending resistance, flame resistance and heat yellowing resistance.

Description

technical field [0001] The present invention relates to a resin composition capable of imparting flame retardancy or flame resistance, and a paper or fiber processed product treated therewith. Background technique [0002] Various paper and fiber processed products are used in various applications, and synthetic resins are widely used as their physical property improvers. In recent years, flame retardancy of paper and fiber processed products used in applications such as building materials and automobile interior materials has been demanded, and synthetic resins corresponding thereto have also been developed. [0003] Usually, as a method of making a synthetic resin flame-retardant, the method of adding a flame retardant to a resin component is mainly mentioned. For example, known inorganic flame retardants such as red phosphorus, phosphate, antimony trioxide, aluminum hydroxide, magnesium hydroxide; halogen flame retardants such as pentabromodiphenyl ether, octabromodiphen...
