Abstract

The invention discloses a preparation method of a curing agent for a resin anchoring agent. The preparation method comprises steps as follows: (1), raw materials including 4-32 parts by weight of an initiator, 2-25 parts by weight of alcohol, 0.5-5 parts by weight of a thickening agent, 50-150 parts by weight of water, 80-160 parts by weight of inorganic filler and 1-3 parts by weight of pigmentsare weighed; (2), the alcohol and the thickening agent are mixed, the mixture is dispersed at high speed for 10-20 min, the temperature is increased to 20-40 DEG C, the mixture is stirred for 5-30 min, then water is added, stirring is performed for 20-60 min, and a product becomes colloidal; (3), the initiator, the inorganic filler and the pigments are added to the colloid in sequence, stirring iscontinued for 30-60 min, the materials are mixed to be homogeneous, and the curing agent for the resin anchoring agent is obtained. The curing agent for the resin anchoring agent is uniform and finein appearance and has the advantages of being resistant to temperature and freeze thawing and good in colloidal stability, preventing bleeding separation and precipitation and the like. The curing agent has excellent pseudoplastic property and is high in viscosity when in static state, and viscosity is reduced rapidly during high-speed shearing and restores when the shear force disappears.

Description

technical field [0001] The invention relates to a method for preparing a curing agent for a resin anchoring agent, and belongs to the field of anchoring agents. Background technique [0002] Anchoring agent is the most widely used anchoring bonding material at present. It is a viscous anchoring bonding material prepared in a certain proportion from unsaturated polyester resin, curing agent, accelerator and other auxiliary materials. The two components of resin cement and curing agent are separated and packaged by polyester film in the form of medicine rolls. It has excellent properties such as long shelf life, convenient construction and fast curing at room temperature, high bonding strength, reliable anchoring force and good durability. It plays an important role in the fields of coal mine shaft support, shaft installation, construction engineering, road and bridge engineering, tunnel engineering, facility foundation and component anchoring. [0003] Anchoring agent automa...
