Abstract

The invention discloses a silane-modified transition-metal-supported polystyrene building material. The polystyrene building material is prepared from the following raw materials in parts by weight: 6 to 8 parts of zirconium oxychloride, 7 to 9 parts of nickel chloride, 10 to 14 parts of graphene oxide, 20 to 30 parts of styrene, 0.1 to 0.2 part of dibenzoyl peroxide, 100 to 110 parts of polystyrene, 3 to 4 parts of polyamide wax micropowder, 0.4 to 1 part of 2-bromine-4-methylphenol, 2 to 3 parts of polyacrylamide, 0.5 to 1 part of dithio-salicylic acid, 0.3 to 1 part of mercaptan butyltin, 2 to 3 parts of calcium petroleum sulfonate, 0.6 to 1 part of silane coupling agent kh560, 6 to 8 parts of bentonite, 2 to 3 parts of terpilenol and 3 to 4 parts of talcum powder. By adding the saline coupling agent kh560, the dispersity of filler among copolymers can be improved effectively, and the stability strength of a finished product is improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a silane-modified polystyrene building material loaded with transition metals and a preparation method thereof. Background technique [0002] Polymer nanocomposites (composed of a polymer matrix (continuous phase) and nanofillers (dispersed phase). Among them, the nanofiller has at least one dimension smaller than nanometers. When the nanofiller is well formed in the polymer matrix Dispersion can significantly improve the performance of nanocomposites. Compared with traditional polymer composites, polymer nanocomposites use less filler and have significant effects; [0003] The performance of polymer nanocomposites is affected by two factors: the dispersion of nanofillers and the interfacial interaction between nanofillers and polymer matrix; Dispersion. Nanoparticles usually have a strong tendency to agglomerate, resulting in a decrease in the specific surface area o...
