Description of the Invention: [Technical Field] The present invention relates to a polyurethane foam, and more particularly to a premixed composition for foaming for preparing a polyurethane foam, and using the foreseeable composition Into the foam material. [Prior Art] Polyurethane foam is an important material for people's livelihood or industry. Polyurethane foam is widely used in industries such as furniture, packaging, fabrics and insulation materials, and its properties depend on the final application. Basically, polyurethane foam is obtained by a mixture polymerization reaction of a diisocyanate (diiS0cyanate), a polyol, and a diol or a diamine as a chain extender. Polyurethane foams which are generally obtained using polyester polyols have the disadvantage of poor weatherability, i.e., hydrolysis, cracking, and yellowing under conditions of high humidity, high heat, and strong ultraviolet rays. TW200823242 discloses a non-yellowing polyurethane foam. The polyurethane foam is formed by forming at least one aliphatic isocyanate (at least one polyol) into at least one prepolymer; the prepolymer, the foaming agent, the interface The active agent, catalyst, crosslinking agent and water are prepared by emulsification and foaming reaction. This patent publication uses an aliphatic isocyanate to reduce the reactivity of the isocyanate terminal group of the prepolymer. Therefore, it is necessary to use a crosslinking agent to solve the problem. In addition, this patent publication does not explicitly disclose the type of polyol and needs to prepare a prepolymer first, which makes the entire loading vehicle complicated and time consuming; The agent is mainly amine, which will cause the foam to be yellowed easily, and at the same time, the mechanical properties of the foam are limited by 201217431. In addition to the above problems, the volatile organic solvent (such as pentane, used in this patent publication) Two gas, 1 is the milk T condition temple), it will also cause dyeing, and it poses a threat to the health of the on-site operators. And /Λ2ΓΓ253821A1 reveals a kind of polyurethane foam with a hygienic and good hygroscopicity. Amine vinegar foam is mainly Polypolyol, aliphatic isocyanate, surfactant, catalyst and foaming: made by the reaction. This patent publication is not suitable for the hygroscopicity and anti-yellowing on the gauze for the purpose of solving the conventional (10) application. The disadvantage is that the desired properties are achieved by the control of aliphatic isocyanates, polyester polyols and surfactants. However, the polyester polyol of this patent publication is a solid or highly viscous fluid for use. It is inconvenient, and because the polyester polyol has better hygroscopicity, the accumulation of moisture over a long period of time may cause hydrolysis of the polyurethane foam. From the above formula for forming a polyurethane foam, it is known that Although polyurethane foam can overcome the problem of yellowing, it still has problems such as easy cracking, hydrolysis and deterioration of mechanical properties. Therefore, it has polyurethane ester foam which is resistant to cracking, hydrolysis, yellowing and mechanical properties. Cotton has yet to be developed and improved. [Inventive content] Therefore, the first object of the present invention is to provide a foam material which is low in viscosity and which facilitates subsequent operations and which can be subsequently formed. The premixed composition for foaming having excellent mechanical properties. Thus, the premixed composition for foaming of the present invention comprises a polyether polyol, a blowing agent, a catalyst, a photothermal agent and a surfactant. Polyphony 201217431 Polyol is a copolymer selected from propylene oxide and trihydrocarbyl propane, a copolymer of propylene oxide and ethylene oxide and trishydroxypropyl propane, epoxy propylene and ethylene oxide. A copolymer with glycerol or a combination of the above copolymers. The second object of the present invention is to provide a foamed material having yellowing resistance, cracking resistance, hydrolysis resistance and mechanical properties. The invention discloses a foamed material obtained by reacting a premixed composition for foaming as described above with at least one diisocyanate. The premixed composition for foaming of the present invention utilizes a specific type of poly Shouting the polyol' makes the pre-mixed composition have a low viscosity for subsequent operations, and allows the subsequently produced foamed material to have the advantages of anti-yellowing, hydrolysis resistance, crack resistance and good mechanical properties. [Embodiment] The premixed composition for foaming comprises a polyether polyol, a foaming agent, a catalyst, a photothermal agent, and a surfactant. Wherein, the polyether polyol is a copolymer selected from the group consisting of a copolymer of propylene lactide and dimethicone, a copolymer of propylene oxide and ethylene oxide and trimethylolpropane, propylene oxide and a copolymer of ethylene oxide and glycerol, or a combination of the above copolymers. The foamed material is obtained by reacting a premixed composition for foaming as described above with at least one diisocyanate. Conventional polyester polyols are solid or highly viscous fluids at room temperature. When applied, it is usually required to be heated or added with a solvent to reduce the viscosity or convert it into a solution state for subsequent operations. The polyether polyol used in the present invention is a liquid having a low viscosity and high fluidity at room temperature, which does not require a complicated pre-treatment step, which is beneficial to the process adjustment 5 201217431. Significantly reduce the time and cost of the entire process. The present invention increases the crosslinking density by performing a polymerization reaction using a poly-polyol having a radical end group generated by ring opening of propylene oxide or ethylene oxide with a diisocyanate ( cr〇ssHnk density) 'The foam material obtained in the subsequent stage is not susceptible to thermal cracking, and has better thermal stability, and the foam material has better mechanical properties (such as hardness, tensile strength, etc.). The polyether polyol has better hydrolyzability than the conventional polyester polyol, so that the subsequently obtained foamed material does not hydrolyze after absorbing moisture or in a humid environment. Therefore, the pre-blended composition for foaming formed by using the specific polyether polyol of the present invention can make the subsequently obtained foamed material have both crack resistance, hydrolysis resistance and better mechanical properties, etc. It is more useful for products such as underwear, padding or cushions. When the specific polyether polyols enumerated above are used in combination, the mixing ratio thereof is not particularly limited. Preferably, the polyether polyol in the premixed composition for foaming can be used in combination with a general polyether polyol to impart a plurality of mechanical properties to the foamed material. Typical polyether polyols include, but are not limited to, the commercial product manufactured by D〇w Chemical Co., Ltd.: HF505. Preferably, the polyether polyol has a weight average molecular weight ranging from 3,000 to 5,000. Preferably, in the polyether polyol, the content of ethylene oxide is in the range of 〇3 to 3% based on the total content of ethylene oxide and propylene oxide. More preferably, the content of ethylene oxide ranges from 15 to 30%. When the content of oxime 201217431 is too much, it will make the polyether more unfavorable for the preparation and operation on the process. The viscosity of the south, the type of the hair detector is not particularly limited, and its function is to form a large amount of gas by using a volatile property or to generate a large amount of gas with a dioxic atmosphere to form a foamed material. In the second place, the blowing agent is selected from water, an organic solvent or the like. It is worth mentioning that 'a specific example of the present invention is to make ^ as foam
