Problems solved by technology

Although the existing heat-insulating protective fabrics can play a certain role in heat-insulating protection, the effect is not very good. If a kind of protective material that can absorb heat can be invented at the same time as heat-insulating, it can play a greater role in firefighters. good protection

Embodiment 1

[0020] The thermal protective fabric with memory function of the present invention uses a temperature phase change material mixed with spinning masterbatch to obtain a fiber mixture as a raw material, wherein the temperature phase change material is n-heptadecane with a purity of 98% and a purity of 98%. 99% n-octadecane, 96% n-nonadecane purity, the spinning masterbatch is a mixture of nylon, polybenzimidazole, polyurethane, polypyrrole, polyaniline; then the fiber mixture is melt-spun The thermal memory fiber is obtained, and then the thermal memory fiber is spun to form a sheet-like fiber aggregate, and the thermal protection material is obtained.

Embodiment 2

[0022] On the basis of Example 1, in order to make the temperature phase change material achieve a better phase change endothermic effect, a preferred embodiment is that the temperature phase change material is n-heptadecane with a purity of 99%, and a purity of 99.2%. N-octadecane, the n-nonadecane with a purity of 97%, the spinning masterbatch is a mixture of polyvinyl chloride, polyether alum, and polyacrylonitrile, and the other parts are exactly the same as in Example 1.

Embodiment 3

[0024] In order to realize the production of the heat protection fabric with memory function, a preferred embodiment is a method for manufacturing the heat protection fabric with memory function of the present invention, the steps of the method are:

[0025] The first step, in order to prepare fibers from the temperature phase change material, mix it with the spinning material, mix the temperature phase change material with the spinning organic masterbatch evenly, and obtain the fiber mixture; the temperature phase change material has a purity of 99 % n-heptadecane, the n-octadecane with a purity of 99.2%, the n-eicosane with a purity of 97%, the content of the temperature phase-change substance is 4.2% of the total mass of the fiber mixture, and then added in the phase-change substance as Ethylene propylene rubber as tackifier; spin masterbatch is a mixture of polyethylene oxide, polymethyl methacrylate, and polytrimethylene terephthalate.

[0026] In the second step, in orde...

Abstract

The invention discloses a thermal protection material with a memory function, and a preparation method thereof. The thermal protection material adopts a fiber mixed material prepared by mixing a temperature phase change substance and spinning masterbatches or an inorganic fiber material as a raw material, and is prepared by spinning thermal memory fibers prepared from the fiber mixed material subjected to melt spinning process; the preparation method comprises the following steps: firstly uniformly mixing the temperature phase change substance and the spinning masterbatches or the inorganic fiber material to obtain the fiber mixed material; then melting the fiber mixed material, and using the melt spinning process to make the fiber mixed material into the thermal memory fibers; spinning the thermal memory fibers to obtain continuous monofilament fibers or sheet-like fiber polymer so as to obtain the thermal protection material with the memory function. The thermal protection material provided by the invention has an excellent insulating effect and good heat absorptivity, can well protect working personnel such as firemen, and is simple in preparation method and low in cost.

Description

technical field [0001] The invention relates to a production method of a clothing fabric, in particular to a preparation method of a thermal protection fabric with a memory function. Background technique [0002] In a fire, the external ambient temperature is 38°C~66°C, or even higher, and the heat flow to the clothing surface can be as high as 80kW / m 2 Above, therefore, firefighting clothing must be able to provide good temperature regulation function, high insulation heat insulation function, permanent flame retardant performance, and good waterproof, breathable, antistatic and reflective performance, so as to ensure the personal safety of firefighters during fire rescue. Safety. In the design of firefighting clothing, the selection and combination of protective materials should fully meet the requirements of rescue operations in special fire environments, and can play the protective role of insulation stab resistance and heat insulation and moisture permeability. Althou...
