Abstract
The invention discloses a method for preparing a coal-based functional reinforcing powder material. The method comprises the steps of (1) smashing anthracite into anthracite particles and soaking the anthracite particles in acid, (2) adding the acid-soaked anthracite particles to a sweller for swelling treatment, (3) adding the anthracite particles treated with swelling to 20 wt% - 30 wt% glacial acetic acid for intercalation modification and then adding the anthracite particles treated with intercalation modification in the glacial acetic acid to acrylamide for intercalation modification, (4) mixing the anthracite particles obtained from the step (3) with a modifier and conducting ball milling in a ball mill, and (5) dewatering and drying the anthracite particles obtained from the step (4) to obtain the product. According to the method, anthracite is adopted and treated with acid leaching, swelling and intercalation modification so that the acting force between aromatic lamellar structures can be weakened; then mechano-chemical modification is conducted to refine the anthracite particles, so that surface activity is improved and reinforcing performance is remarkable, and comprehensive performance of rubber composites can be improved.
Description
Technical field
The present invention relates to functional powder Material Field, especially relate to a kind of preparation method of coal-based functional enhancing powder body material.
Background technology
Coal mainly forms [Haenel M W.Recent progress in coal structure[J] .Fuel, 1992,71 (11): 1211-1223. by condensation aromatic nucleus elementary cell and a small amount of hydroaromatic ring, alicyclic ring and heterocycle etc.].The structural unit periphery of coal is except connecting [1. Shinn J H.From coal to single-stage and two-stage products:A reactive model of coal structure[J] .Fuel alkyl group side chain, 1984, 63 (9): 1187-1196. is Liu D 2., Qiu J, Li J.Physical structure and combustion properties of super fine pulverized coal particle[J] .Fuel, 2002, 81 (6): 793-797.], also have some as carboxyl (COOH), hydroxyl (0H), the oxygen-containing functional group such as methoxyl group and ehter bond and a small amount of mercaptan (R-SH), thioether, disulfide, nitrogenous and the sulfur-bearing functional group such as heterocycle sulphur, give coal higher activity, be conducive to the chemical modification of coal.Therefore, improve research [the 1.
