PBT material coating and preparation method thereof

Abstract

The invention discloses a PBT material coating, which comprises a paint flame retardant base layer, the top surface of the paint flame retardant base layer is provided with an antioxidant layer, and the bottom surface of the paint flame retardant base layer is provided with an adhesion layer; the paint flame retardant base layer is prepared from the following raw materials in parts by weight: 9-11parts of latex paint, 2-3 parts of a flame retardant and 1-2 parts of a fluorescent material; the antioxidant layer is prepared from the following raw materials in parts by weight: 5-7 parts of polyethylene, 3-5 parts of iron powder and 12-14 parts of flame retardant rubber; the adhesion layer is prepared from the following raw materials in parts by weight: 7-9 parts of an adhesive and 1-2 partsof resin; the preparation method of the PBT material coating comprises the following steps: (1) manufacturing the adhesion layer; (2) producing the paint flame retardant base layer; and (3) producingthe antioxidant layer. The antioxidant layer is arranged on the surface of the paint flame retardant base layer to form protection for the paint flame-retardant base layer, prevents the paint flame retardant base layer from oxidizing and falling off, and weakens the flame-retardant performance of the paint flame retardant base layer; and the arrangement of the adhesion layer can ensure that the paint flame retardant base layer is more firmly combined with PBT materials and the paint flame retardant base layer.

Description

technical field [0001] The invention relates to the field of PBT, in particular to a PBT material coating and a preparation method. Background technique [0002] Polybutylene terephthalate, English name polybutylene terephthalate (referred to as PBT), belongs to the polyester series, which is composed of 1.4-pbt butanediol (1.4-Butylene glycol) and terephthalic acid (PTA) or terephthalic acid Formic ester (DMT) polycondensation, and milky white translucent to opaque, crystalline thermoplastic polyester resin made through mixing procedures; together with PET, it is collectively referred to as thermoplastic polyester, or saturated polyester; PBT itself has a certain However, some special industries (such as the mining industry) put forward higher requirements for the flame retardant performance of PBT, and the more economical way to increase the flame retardant performance of PBT is to set a flame retardant coating layer on the surface of PBT, while the existing flame retardan...
