Abstract

The invention discloses a polyketone composition applied to supporting and sliding elements in architectural engineering. The polyketone composition is prepared from the following raw material components in parts by mass: 71.5-98 parts of aliphatic polyketone resin, 0.3-10 parts of abrasion-resistant agents, 1-10 parts of polymer toughening agents, 0.3-1.5 parts of heat stabilizers, 0.1-1 part oflubricants, 1-5 parts of compatilizers and 0.3-1 part of other auxiliary additives. The polyketone composition applied to supporting and sliding elements in architectural engineering has excellent mechanical property, heat resistance, chemical resistance, low-temperature property and self-lubrication property, particularly has low friction coefficient, high abrasion resistance and high compressivestrength, and is applicable to conditions with higher load and wider use of temperature. Through combination of the formula of the polyketone composition, compared with the existing polyketone material extrusion molding scheme, a plate extruding scheme and a compression molding scheme which are used as two new product preparation processes are provided; the problem that the extrusion pelletizing-injection molding scheme is incapable of molding large-sized products and thick products is solved.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a polyketone composition for construction engineering supporting sliding elements and a preparation method thereof. Background technique [0002] Based on the requirements of shock absorption and isolation and flexible design, large-scale buildings and bridge projects need to use a support structure that can provide support reaction force and allow the support to slide in a small displacement in the design direction through the sliding elements in the structure. The support structure is generally designed to last the life of the building. At the same time, with the continuous advancement of construction technology, the bearing capacity of the supporting structure per unit area has been continuously improved, while its own size has shown a trend of continuous shrinking. Under this trend, sliding elements are required to have high load carrying capacity, extremely lo...
