Abstract
The invention discloses an alloy material with a ceramized surface and a preparation method and application thereof. The alloy material comprises the following components in parts by weight: 20-30 parts of polypropylene resin, 20-30 parts of polyamide resin, 10-20 parts of ceramic forming filler, 20-25 parts of phosphorus-nitrogen flame retardant, 3-5 parts of compatilizer, 1-5 parts of charring agent, 1-5 parts of micron cosolvent, 1-5 parts of nano cosolvent and 0-2 parts of other auxiliaries, the melt index of the polypropylene resin is 5-15g / 10min under the conditions of 230 DEG C and 2.16 Kg, and the viscosity coefficient of the polyamide resin is 2.4-2.8. The alloy material has excellent strength, the surface layer can be quickly ceramized at high temperature to form a stable and high-strength ceramic self-supporting body, and the core layer provides overall excellent mechanical properties for the alloy material due to the intermolecular hydrogen-bond interaction of the PA phase.
Description
technical field [0001] The invention relates to the field of polymer materials, and more particularly, to an alloy material with surface ceramization and a preparation method and application thereof. Background technique [0002] In recent years, ceramic polymer has gradually entered everyone's field of vision as a new type of high-efficiency fireproof material. Ceramic polymer is a composite material prepared by compounding some flame retardants, ceramic fillers and fluxes in a polymer matrix. When encountering an open flame, the composite material can be transformed into a self-supporting material. The ceramic body prevents the flame from spreading to the inside of the material, so as to achieve the purpose of efficient flame retardant. [0003] The research on ceramified polymers at home and abroad mainly focuses on ceramified silicon-based polymers. US patent application US4460638A discloses a composite material prepared using high modulus fibers and silazane polymers ...
