Abstract

The invention aims to provide a preparation method of a magnesium oxysulfate binding material artware and the magnesium oxysulfate binding material aiming to solve the problem in the prior art that amagnesium oxysulfate binding material suitable for preparation of artware does not exist and based on the waste reutilization aim, belonging to the technical field of magnesium artware materials. Thepreparation method comprises the following steps: 1) brushing a release agent on the inner surface of a mold by a cleaning mold; 2) preparing the magnesium oxysulfate binding material; and 3) making the artware in the mold by adopting a pasting method. The artware made by the method does not need to be maintained, has the apparent density of more than or equal to 0.80 g/cm<3>, the water absorptionrate of less than or equal to 20.0%, the moisture content of less than or equal to 12.0%, the chloride ion dissolution quantity of less than or equal to 3.0%, the rupture strength of more than or equal to 6.5MPa, the compressive strength of more than or equal to 30.0MPa and the softening coefficient of more than or equal to 0.8, and is not damaged or cracked after 25 freezing and thawing cycles.Moreover, low-grade magnesite and other industrial and agricultural wastes are fully utilized, and the cost of the product is reduced.

Description

technical field [0001] The invention belongs to the technical field of magnesia handicraft materials, and in particular relates to a preparation method of a magnesium oxysulfide gelling material handicraft and the magnesium oxysulfide gelling material used. Background technique [0002] Products based on magnesium oxychloride cementitious materials have been researched at present. It is an air-hardened cementitious material with high strength performance, but the problems of moisture absorption and halogen return, warping and deformation are serious, and it is difficult to overcome at present. Especially more serious defect is prepared on the handicraft with decorative effect, thereby has influenced the attractive in appearance and the service life of handicraft. [0003] The advantage of the magnesium oxysulfide gelling material is that it completely solves the problem that the magnesium oxychloride gelling material absorbs moisture and returns to halogen and is easy to w...
