Abstract

The invention belongs to the technical field of bank financial equipment manufacturing, and relates to a cement-based composite material with high drilling resistance used in bank financial equipment. The composite material is characterized by comprising the following components such as cement, siliceous dust, carborundum, an efficient water reducer, steel fiber and water at the weight ratio of 1:(0.10-0.20):(1.4-2.6):(0.005-0.010):(0.30-0.45):(0.23-0.29). The cement-based composite material is applied to the technical field of bank financial equipment, and has the following advantages that the carborundum with Mohs hardness up to 9.0 is taken as an aggregate so as to greatly improve the drilling resistance of the cement-based composite material; and the composite material is naturally cured without high-temperature steam or dry-heat curing procedure, thus simplifying the operating procedures, saving the energy cost and being applicable to large-scale production.

Description

technical field [0001] The invention belongs to the technical field of bank financial equipment manufacturing, and in particular relates to a novel cement-based composite material with high anti-drilling performance. Background technique [0002] The cabinet walls of banking financial equipment are mostly made of metal materials, which are easily penetrated by electric drills and other tools, resulting in the theft of valuables inside. The anti-drilling performance is one of the important performances of banking financial equipment. At present, the foreign method to solve the anti-drilling performance is to use special steel, which is not only expensive, but also has unsatisfactory other comprehensive properties such as flame cutting resistance. [0003] Cement-based composite materials are used in the field of banking and financial equipment in the form of a "sandwich" structure, which significantly improves the comprehensive performance of the cabinet wall. Therefore, the...
