Abstract

The invention discloses a high-permeability sand-fixing primer, which is prepared from the following components in parts by weight: 400-600 parts of a water-based nano inorganic silicon resin, 300-500 parts of deionized water, 30-70 parts of potassium silicate, 30-70 parts of ethylene glycol, 30-50 parts of a toughening agent, 7-12 parts of a defoaming agent, 7-12 parts of a penetrating agent and 3-7 parts of a coupling agent. According to the invention, a water-based nano inorganic silicon resin is compounded with nano modified potassium silicate, a coating material system with high inorganic base material adhesive force is provided, and through compounding of the three penetrating agents, the penetrating performance of the water-based coating material system is further improved, and the sand fixing and sealing effects of the high-permeability sand-fixing primer are improved; and the high-permeability sand-fixing primer is applied to the field of building decoration, can be directly used for the sandy and dusty concrete floor, reduces the pretreatment process of the concrete floor, reduces the coating cost, and saves a large amount of manpower and material resources.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-permeability sand-fixing primer. Background technique [0002] Concrete is the most widely used and cheap building material. In my country's construction projects, more than 80% of the buildings are made of concrete. At present, when a concrete building is being renovated, it is usually necessary to plaster and level the ground with cement mortar, resulting in rough ground, which is prone to cracks, sand, and ash. During construction, the surface of the concrete floor with severe sand and ash Cut away and use a closed sand-fixing primer on smooth cut surfaces. If the existing sand-fixing primer is used directly on the rough ground, the sand-fixing effect is not good, and it is difficult to meet the construction requirements. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the pr...
