The flame-retardant high cold-resistant PU raincoat leather is characterized by comprising base cloth, a water-based PU bottom layer, a water-based cold-resistant foamed resin middle layer and a flame-retardant water-based resin upper layer, wherein the water-based PU bottom layer, the water-based cold-resistant foamed resin middle layer and the flame-retardant water-based resin upper layer are coated on the base cloth and are sequentially connected from bottom to top.
Description
Technical Field
The invention relates to the field of clothing materials, in particular to flame-retardant high-cold-resistance PU raincoat leather and a preparation method thereof.
Background
The raincoat originates from China, and refers to rain-proof clothes made of waterproof cloth, the waterproof cloth is suitable for being made of adhesive tapes, oil cloth, plastic films and the like, the modern raincoat waterproof cloth emphasizes air permeability, and the air-permeable raincoat is beneficial to the fact that hot and humid water can be dispersed out of the raincoat when a user wears the raincoat, and the comfort level is improved.
The raincoat leather is a material for preparing the raincoat, belongs to one of clothes leather, most of raincoat leather materials on the market still adopt PVC leather, although the PVC leather is low in price, the air permeability is poor, and PU raincoat leather is good in air permeability and wear resistance, flammable, poor in cold resistance, easy to age under a low-temperature condition and not suitable for being used under an ultralow-temperature environment, so that the flame-retardant high-cold-resistance PU raincoat leather can meet diversified requirements of the market at present.
Disclosure of Invention
The invention aims to provide the flame-retardant high-cold-resistant PU raincoat leather which is good in air permeability and flame retardance, light and durable, and aims to overcome the existing defects.
The above purpose is realized by the following scheme:
the utility model provides a fire-retardant high cold-resistant PU raincoat leather, its characterized in that includes the base cloth to and coat waterborne PU bottom, the cold-resistant foamed resin intermediate level of waterborne, the fire-retardant waterborne resin upper strata on the base cloth, from bottom to top connect gradually, waterborne PU bottom laminate with the one side of base cloth.
A fire-retardant high cold-resistant PU raincoat leather of high pressure resistant, its characterized in that: the water-based PU bottom layer is prepared from the following raw materials in parts by weight: 70-80 parts of waterborne polyurethane resin, 2-4 parts of hydroxypropyl methyl cellulose, 1-2 parts of ethylenediamine and 0.2-0.4 part of glycidyl ether.
A fire-retardant high cold-resistant PU raincoat leather, its characterized in that: the water-based cold-resistant foamed resin middle layer is prepared from the following raw materials in parts by weight: 110-140 parts of waterborne polyurethane resin, 0.3-0.5 part of bentonite, 1-2 parts of propylene glycol alginate, 2-4 parts of foaming agent, 2-4 parts of N, N-methylene bisacrylamide, 2-4 parts of castor oil, 1-2 parts of glass fiber, 1-2 parts of sodium silicate and 1-2 parts of dioctyl sebacate.
A fire-retardant high cold-resistant PU raincoat leather, its characterized in that: the upper layer of the flame-retardant water-based resin is prepared from the following raw materials in parts by weight: 70-80 parts of waterborne polyurethane resin, 2-4 parts of kaolin, 0.08-0.1 part of attapulgite, 1-2 parts of dioctyl sebacate and 1-2 parts of N-butyldiethanolamine.
A fire-retardant high cold-resistant PU raincoat leather, its characterized in that:
the thickness of the water-based cold-resistant foaming resin middle layer is 0.2-0.5mm.
A fire-retardant high cold-resistant PU raincoat leather, its characterized in that:
the thickness of the water-based PU bottom layer is 30-50 μm.
A fire-retardant high cold-resistant PU raincoat leather, its characterized in that:
the thickness of the upper layer of the flame-retardant water-based resin is 25-70 μm.
A fire-retardant high cold-resistant PU raincoat leather, its characterized in that: the preparation method comprises the following steps:
(1) Uniformly mixing waterborne polyurethane resin, hydroxypropyl methylcellulose, ethylenediamine and glycidyl ether in parts by weight, adding the mixture into a reaction kettle, heating to 60-70 ℃, stirring for 20-30Min at the rotating speed of 70-100r/Min to obtain a waterborne PU bottom layer molten material, coating the molten material on base cloth, drying for 1-2h at the temperature of 90-120 ℃, and cooling for 2-4h at room temperature to obtain the base cloth coated with the waterborne PU bottom layer for later use;
(2) Uniformly mixing the waterborne polyurethane resin, bentonite and propylene glycol alginate in parts by weight, adding the mixture into a reaction kettle, heating to 50-60 ℃, stirring for 20-30Min at a rotating speed of 70-100r/Min, adding a foaming agent, N-methylene bisacrylamide, castor oil, glass fiber, sodium silicate and dioctyl sebacate, cooling to 45-50 ℃, stirring for 20-40Min at a rotating speed of 40-50r/Min, uniformly mixing, foaming, coating the foamed emulsion on the base cloth coated with the waterborne PU bottom layer obtained in the step (1), and drying for 1-2h at 80-110 ℃ to obtain the base cloth coated with the waterborne PU bottom layer and the waterborne cold-resistant foaming resin for later use;
(3) Uniformly mixing the waterborne polyurethane resin, kaolin, attapulgite, dioctyl sebacate and N-butyldiethanolamine in parts by weight, adding into a reaction kettle, heating to 60-80 ℃, stirring for 20-30Min at the rotating speed of 80-120r/Min, coating on the base cloth coated with the waterborne PU bottom layer and the waterborne cold-resistant foaming resin obtained in the step (2), and drying for 1-2h at the temperature of 100-110 ℃ to obtain the polyurethane foam.
The beneficial effect of this application does:
(1) The flame-retardant high-cold-resistance PU raincoat leather provided by the invention is reasonable in structure, comprises a base cloth, and a water-based PU bottom layer, a water-based cold-resistant foamed resin middle layer and a flame-retardant water-based resin upper layer which are coated on the base cloth and are sequentially connected from bottom to top, wherein the water-based PU bottom layer is attached to one surface of the base cloth, so that the flame-retardant high-cold-resistance PU raincoat leather has good waterproof and air permeability, is light in weight, is soft and is convenient to carry.
(2) The glass fiber, sodium silicate and other raw materials are added into the middle layer of the water-based cold-resistant foaming resin, so that the cold-resistant foaming resin has a cold-resistant effect and simultaneously has a synergistic effect with other raw materials, and the flexibility of the raincoat is not influenced;
