Abstract

The invention discloses self-levelling gypsum mortar with high wear resistance, relating to construction materials. According to the invention, the problems of bad wear resistance and limited application range of the present self-levelling gypsum mortar are solved. The self-levelling gypsum mortar comprises the following ingredients: 40-60 wt% of high-strength gypsum, 0-40 wt% of constructional fine sand, 0-40 wt% of fly ash, 2-4 wt% of exciting agent, 1 wt% of dispersible gelatine powder, 0.5wt% of water reducer, 0.1 wt% of antifoaming agent, 0.05 wt% of cellulose ether, and 0.05 wt% of retarder with mixing uniformly. Under standards of gypsum-base flowing leveling mortar JC/T1023-2007, by adding the constructional fine sand and fly ash, the wear resistance and surface hardness of the self-levelling gypsum mortar is improved, and the application of the self-levelling gypsum mortar is extended.

Description

A high wear-resistant self-leveling gypsum mortar

技术领域 technical field

本发明涉及建筑材料，具体涉及自流平石膏砂浆。The invention relates to building materials, in particular to self-leveling gypsum mortar.

背景技术 Background technique

现有自流平石膏砂浆中的胶凝材料均采用建筑石膏，由于建筑石膏本身粘结力低，不能添加无胶凝性质的高硬度材料，如建筑用细沙和粉煤灰等；从而现有自流平石膏砂浆耐磨性差，影响了它的使用范围。The cementitious materials in the existing self-leveling gypsum mortar all adopt building gypsum, because the cohesive force of building gypsum itself is low, can not add high-hardness materials without gelling properties, such as fine sand and fly ash for construction, etc.; thus the existing Self-leveling gypsum mortar has poor wear resistance, which affects its scope of use.

发明内容 Contents of the invention

本发明的目的在于克服现有产品的缺点，提供一种高耐磨的自流平石膏砂浆，The purpose of the present invention is to overcome the shortcoming of existing products, provide a kind of highly wear-resistant self-leveling gypsum mortar,

解决现有自流平石膏砂浆耐磨性差，使用范围受限制的问题。The problem that the existing self-leveling gypsum mortar has poor wear resistance and limited application range is solved.

本发明的任务是通过以下技术方案来实现的：Task of the present invention is achieved through the following technical solutions:

一种高耐磨的自流平石膏砂浆，由以下重量百分比的组分：A high wear-resistant self-leveling gypsum mortar, consisting of the following components by weight percentage:

本发明采用高强石膏为基本胶凝材料，同时利用激发剂(氧化钙)激发了原本无胶凝性质的高硬度材料——建筑用细沙(主要为二氧化硅)或粉煤灰(成份主要为二氧化硅和三氧化二铝)的活性，产生一定的粘结力，再加上与上述材料相匹配的微量化学辅料均匀混合而制成。The present invention uses high-strength gypsum as the basic gelling material, and at the same time utilizes the activator (calcium oxide) to stimulate the original high-hardness material without gelling properties - fine sand for construction (mainly silicon dioxide) or fly ash (mainly composed of It is made of silicon dioxide and aluminum oxide) to produce a certain amount of cohesive force, plus a small amount of chemical auxiliary materials that match the above materials are evenly mixed.

本发明是在满足《石膏基自流平砂浆》JC/T1023-2007标准的条件下，由于加入了高硬度材料——建筑用细沙或粉煤灰，从而提高了自流平石膏砂浆的耐磨性和表面硬度，扩展了其用途。The present invention is under the condition of meeting the JC/T1023-2007 standard of "Gypsum-Based Self-Leveling Mortar", and improves the wear resistance of self-leveling gypsum mortar due to the addition of high-hardness materials - fine sand or fly ash for construction and surface hardness, expanding its use.
