Effect. [Prior Art] According to the technical field of PU (polyurethane) foam, PU foam has been widely used in pillows, medical mattresses, office chair cushions, bedding mattresses or shoe materials. There is a PU memory foam with uniform pressure relief on the market, and the conventional pu memory foam utilizes a polyether polyol (P〇lyether polyol) 〇5 ~9〇0/〇 and isocyanate vinegar (IS0Cyanate) 2~60%, first mixed evenly at room temperature, then I5 by carbon dioxide reaction (产生2) or other low volatility A foaming agent such as MC (methylenechl〇ride5CH2Cl2) is poured into a molding die such as a pillow, a medical mattress, an office chair cushion, a bedding mattress or a shoe material, and the temperature is controlled between 30 ° C and 50 ° C. The foaming time is about 5 to 10 minutes, and the molding is made. 20 In the United States, Fnsby used a micro encapsulation particle about 7 years ago as an additive to make a woven fabric and a hydrophilic (open-cell) foam with insulating and sensation effects. Foam is used in a variety of products such as home furnishing or medical bed, but the foam made by adding the micro-encapsulated material (micr〇encapsulati〇n 4 1265170 particle) is not very Significant temperature control (hydrophilic effect), sometimes even no difference with the formula without added heat powder. Therefore, the conventional PU memory foam, including the PU foam made by the currently known PU memory foam leader, has the following disadvantages due to the fact that the material formulation and process used therein have not been considered: 1> The conventional PU memory foam is non-hydrophilic (hydr〇ph〇bic) pu. / cotton, so it does not have obvious hydrophilic properties, that is, it does not have obvious hygroscopicity ( Moisture absorbing) and thermo absorbing, when g is in contact with the human body, the moisture and hot air generated by the human skin at the contact surface cannot be effectively dissipated, resulting in rapid heat storage at the contact surface, and no dryness is achieved. The wet and cool (endothermic) effect greatly affects the user's comfort and is not conducive to the application of the foam. <2> Although the conventional PU memory foam has a relatively soft degree, the softness does not have low temperature resistance, so the conventional pu memory foam has a temperature sensitive I5 feeling, and the temperature is below l〇°C. It will gradually harden. When the ambient temperature is lower than • Celsius, it may be as hard as wood. Therefore, when it is used in a cold area, it must be heated (opening the heating) for a period of time before it has a soft effect, and the ambient temperature is limited. Relatively affect the application range of foam. - > The known memory foam has poor oxidation resistance and hydrolysis resistance, and 20 pairs affect the life of the foam. < 4 > After the reaction, the conventional non-hydrophilic (hydr〇ph〇bic) pu ü ü 忆 泡 T 己 己 己 己 己 己 己 DA DA To To To To To To To To To 己 己 己 己 己 己 己 己 己 己 己 己 己 己 己 己 己Considering; and after the formation of the bubble, the name of the 3 residual catalyst (amine), there will be a pungent taste, 1265170 unfavorable ^ when used as a pillow, mattress or cushion. In general, the durability of latex foam is not good, and the valley is easily oxidized or affected by perfumes and alcohols (alcohol). Powder is its shortcoming. Θ ^ Therefore, the use of non-hydrophilic PU memory foams in applications, especially 5, when used on pillows, medical mattresses, bedding mattresses, etc., is still not enough. 2 consumers in terms of quality and function. The requirements for comfort are also plagued by the use of the fee.

With the bed shown in Fig. 1, the method for preparing the hydrophilic sputum memory of the present invention can be completed according to the following steps: The production of 匕巧16 16 1265170 Step <1> provides a hydrophilic PU prepolymer; The PU prepolymer comprises a first polyether polyol (polyether polyol) of 1 to 80% but preferably 40 to 70%, and isocyanate 1 to 70% but preferably 30 to 60%; The first 5 polyether polyol contained in the PU prepolymer has a molecular weight of between 600 and 2000, and contains at least 40 mole% of an ether group (·Ε0_), and the ether group (-E0-) content is 20~99.9%; #Step<2> Provide molding molds for various products, such as pillows, cushions, 'backrests, protective gear, toys, mattresses or insoles, etc.; ίο Steps <3> The hydrophilic pH prepolymer prepared is preferably 1 to 70% but preferably 40 to 60%, and 1 to 50% of the acrylic polymer compound (Acrylic Emulsion Polymer) but 5 to 20%. Preferably, and the second polyether polyol (p〇lyether P〇ly〇l) l~50% but preferably 5~20% as a hair The elemental material mainly constitutes the I5 component, and is added with an appropriate proportion of water, surfactant, (Surfactant), ammonia catalyst (Amine Catalyst) or particulate wrapping material; and the production temperature can be between 5 and 5 (TC) Further, the melting point of the particulate encapsulating material is 28.3 ° C; Step <4> The above acrylic emulsified polymer compound (Acrylic 2 〇 Emulsion p〇lymer), the first polyether polyol and the hydrophilic pu prepolymer (hydrophilic PU prep〇lymer), mixed according to the set weight ratio and / / main into the molding cookware, the mold temperature is controlled between 3 〇 ~ 5 〇〇 c, foam molding process, foaming time of about 5~10 a minute; wherein, the weight of the hydrophilic pu prepolymer accounts for 33 3 to 66.7% of the total weight of the foamed material, but the average is 17 1265170 仏, as shown in the above embodiments 1 to 7; 5> After the foaming is completed, the foamed molded body; the foamed molded 5/1 is taken out from the mold, and the foamed molded body is placed in an oven for high-temperature baking between about 50 and 100 °C. Baking time depends on the size and weight of the object. 'Short for tens of minutes, long for a few In an hour, the dehydration effect is achieved, and the process of the foam product is completed. The high temperature baking operation of the 'step <6> is not in the conventional process, because the conventional PU memory foam is non-hydrophilic and does not need to be dehydrated. In fact, the application of hydrophilic foam to pillows, cushions, backrests, cookware, toys, mattresses or insoles is also a feature of the present invention. Further, in the above process, the hydrophilic PU prq is composed of the first polyether polyol and the isocyanate in an appropriate ratio, but the PU prepolymer may be subjected to a preparation procedure such as a step <;1:> and 15, but according to the existing chemical technology, the first step step ^, and 夂3 > can also be simplified into "one shot tedmique", isocyanate (Isocyanate) Use TDI (T〇luene Diisocyanate) or MDI (Methylene diphenyl diisocyanate), plus polyether polyol such as PEG 600, add ammonia catalyst, surface active 20 agent, chain extender, water and pressure It is composed of Acrylic Emulsion Polymer and then directly molded into a suitable mold for foam molding without proper preparation of a PU prepolymer. The foaming method of the present invention may also first prepare a first hydrophilic 18 1265170 pu prepolymer and a second hydrophilic 1 > 11 prepolymer, the first hydrophilic PU prepolymer system being firstly polymerized. The polyhydric alcohol is polymerized with an isocyanate, the first polyether polyol has a molecular weight of between 600 and 2000, and the second hydrophilic PU prepolymer is formed by combining a second polyether polyol and an isocyanate. The molecular weight of the second polyether polyol is between 5 〇 and 6 ,, and the first hydrophilic PU prepolymer is mixed with the second hydrophilic PU prepolymer and water and a surfactant are added in an appropriate ratio. The ammonia catalyst can be prepared by baking after the foaming process, and the foam of the present invention can be produced. In the above composition of the present invention, the microcapsule material (micr〇encapSulati〇n ίο particle) can be added or not added (occupy ~2〇〇/〇), because the particle wrapping material is added to the foam, it only produces a physical reaction with the foam element without chemical change (chemicai reacti〇n), so with or without adding The microparticle-encapsulating material does not substantially affect the moisture absorbing and thermo absorbing properties of the hydrophilic PU foam of the present invention, that is, the hydrophilic PU foam of the present invention remains Achievable Compared with the conventional memory foam, the hydrophilic PU foam of the present invention has at least the following effects which can not be achieved by the conventional S-type foam. Advantages: 20 <1:> The foam is soft and delicate, and has both moisture absorbing and thermo absorbing. When in contact with human skin, it can contact the skin. The generated moisture and hot air are effectively absorbed and then dissipated to achieve a dry (hygroscopic) and cool (endothermic) effect. <2> This foam has low temperature resistance and is not overly sensitive to temperature. Even if 19 1265170 does not harden below 10C, it can maintain general softness even at minus 15 degrees Celsius. <3> This foam has a pressure releasing function of the memory foam. <4> This foam has the advantage of being non-toxic. <5> This foam does not have the disadvantage of a nasal spray catalyst and skin irritation. The advantages and disadvantages between the foam of the present invention and the conventional memory foam are summarized as follows:
