Problems solved by technology

[0003] At present, although the coated fiber fireproof cloth widely used at home and abroad has achieved the flame retardant effect, when used in outdoor building facilities, it also maintains the service life and long-term gloss of the product, and has good weather resistance and antifouling effect. However, such fireproof cloth products generally have the characteristics of complicated preparation process, complicated operation procedures, and high product cost.

Embodiment 1

[0022] A kind of EVA spray fireproof cloth and its manufacturing method proposed in this embodiment.

[0023] In order to achieve the above object, the present invention adopts the following technical solutions:

[0024] An EVA spray fireproof cloth comprises a fiber base cloth, wherein, the bottom layer and the surface layer of the fiber base cloth are sprayed with an EVA spray layer.

[0025] Preferably, the fiber base cloth is glass fiber cloth, polyester cloth, acrylic cloth.

[0026] Preferably, the spray layer includes the following components: 80 parts of ethylene-vinyl acetate copolymer (EVA), and 17 parts of flame retardant. Here as preferred scheme ethylene-vinyl acetate copolymer (EVA) selects U.S. Dupont EVA particle for use as raw material.

[0027] Preferably, if the color of the fireproof cloth needs to be adjusted, 3 parts of the corresponding color masterbatch can be added to the spray layer.

Embodiment 2

[0036] An EVA spray fireproof cloth proposed in this embodiment includes a fiber base cloth, wherein both the bottom layer and the surface layer of the fiber base cloth are sprayed with an EVA spray layer.

[0037] Further, the fiber base cloth is glass fiber cloth, polyester cloth, acrylic cloth.

[0038] Further, the spray layer includes the following components: 87 parts of ethylene-vinyl acetate copolymer (EVA), 10 parts of flame retardant; here, as a preferred solution, ethylene-vinyl acetate copolymer (EVA) is selected from U.S. Dupont EVA Granules are raw materials.

[0039] Furthermore, if it is necessary to adjust the color of the fireproof cloth, 3 parts of the corresponding color masterbatch can be added to the spray layer.

[0040] The manufacturing method of the above-mentioned EVA spraying fireproof cloth comprises the following steps: S1, fusing; mixing and melting ethylene-vinyl acetate copolymer (EVA) and a flame retardant in a suitable proportion to form a l...

Embodiment 3

[0048] An EVA spray fireproof cloth proposed in this embodiment includes a fiber base cloth, wherein both the bottom layer and the surface layer of the fiber base cloth are sprayed with an EVA spray layer.

[0049] Further, the fiber base cloth is glass fiber cloth, polyester cloth, acrylic cloth.

[0050] Further, the spray layer includes the following components: 85 parts of ethylene-vinyl acetate copolymer (EVA), 12 parts of flame retardant; here, as a preferred solution, ethylene-vinyl acetate copolymer (EVA) is selected from U.S. Dupont EVA Granules are raw materials.

[0051] Furthermore, if it is necessary to adjust the color of the fireproof cloth, 3 parts of the corresponding color masterbatch can be added to the spray layer. If adjustment is not required, the proportion of the flame retardant can be appropriately increased.

[0052] A method for making an EVA spray fireproof cloth, comprising the following steps: S1, fusing; mixing and melting ethylene-vinyl acetate...

Abstract

The invention discloses EVA spraying fireproof cloth and a preparation method thereof. The EVA spraying fireproof cloth comprises fiber base cloth, wherein EVA spraying layers are sprayed on a bottomlayer and a surface layer of the fiber base cloth. According to the fiber fireproof cloth in the application document, the EVA spraying layers are sprayed on the bottom layer and the surface layer ofthe fiber base cloth, and then cooling for curing is performed to form the fireproof cloth; the fiber fireproof cloth product prepared by the process is non-toxic, harmless, environment-friendly, recyclable, high in heat resistance and cold resistance, non-deformable in a relatively hot environment and long in service time; and the original base cloth performance is kept, the tensile and impact strength of the spraying fireproof cloth is enhanced, and the fireproof cloth is bright and beautiful in surface, illumination-resistant, pollution-resistant, easy to clean, simple in raw material, lowin cost, simple in preparation process and convenient to operate, can be widely applied to fireproof sheets and fireproof nets in the building industry, is an excellent material capable of replacing traditional PVC, and has the wide market prospect.

Description

technical field [0001] The invention relates to the technical field of processing polymer textile materials and fireproof net products, in particular to a full PE fireproof net. Background technique [0002] Fire is one of the main disasters faced by human beings. A fire will cause heavy casualties and property losses. At present, the inherent flammability of fiber cloth materials widely used in production and life is an important cause of fires. . In order to prevent the occurrence of fire and avoid personal injury and property loss, people have tried various methods to protect the fiber cloth from fire and make it into a fireproof cloth. [0003] At present, although the coated fiber fireproof cloth widely used at home and abroad has achieved the flame retardant effect, when used in outdoor building facilities, it also maintains the service life and long-term gloss of the product, and has good weather resistance and antifouling effect. However, such fireproof cloth produ...
