Grease for anti-weathering protection of stone

Abstract

The invention relates to a grease for anti-weathering protection of stone, which is prepared from the following raw materials in percentage by weight: 40-45% of polyorganosiloxane, 35-40% of silane, 5-10% of organosilicon and 5-10% of refined quartz sand. The raw materials are proportionally mixed, and subjected to nano treatment in a reaction kettle until the particle size is 0.1-100nm. After the material is applied onto a substrate by dip coating, no trace can be left on the surface of the coated brick, ash mud, natural stone or concrete; and due to the non-drooping characteristic and the longer detention time on the substrate surface, the grease can permeate into the low-porosity building material more deeply. The grease has high acid / alkali resistance, high air permeability and favorable water resistance, and is applicable to adsorptive mineral substrates, such as natural hard laterite, glaze-free vitrified bricks, surface-protecting stone, asbestos cement boards, ash mud, glue mud, natural stone, prefabricated stone, concrete and the like.

Description

technical field [0001] The invention relates to the technical field of anticorrosion materials, in particular to a grease used for weathering protection of stone materials. Background technique [0002] Building materials, especially stone, are widely used. However, during the use of stone, it is often caused by its own water absorption characteristics and atmospheric environmental pollution, chemical corrosion, erosion of moss and lichen, frost cracking, long-term sunlight exposure, alternating cold and hot in winter and summer, and rainwater. Scouring and other natural factors are damaged, resulting in rust spots, water stains, oil stains and even cracks. The emergence of these diseases makes the load-bearing or decorative performance of building materials such as stone disappear, causing regret for a long time. The protection of stone needs to have the characteristics of water resistance, oil resistance and anti-fouling after one-time treatment. When it is used for outdo...
