Abstract

An epoxy resin type anchoring adhesive is prepared from following raw materials: 60-80 parts of epoxy resin, 8-10 parts of raw fiber powder, 2-4 parts of fly ash, 6-8 parts of active diatomite, 1-3 parts of calcium lignosulphonate, 2-4 parts of hydroxymethyl cellulose, 2-4 parts of silicate clinker, 2-4 parts of metakaolin powder, 2-4 parts of ground calcium carbonate powder, 3-5 parts of quartz sand, 2-4 parts of an expanding agent, 50-60 parts of a sodium silicate solution and 80-100 parts of a sodium phosphate solution. The epoxy resin type anchoring adhesive has the beneficial effects as follows: the processing technology is simple, scientific and normative, the formula is reasonable, and the prepared anchoring adhesive has a remarkable curing effect, high adhesive property and obvioususe effect when used in adhesion of a metal anchor with stone and soil.

Description

technical field [0001] The invention relates to the technical field of rebar-planting glue processing, in particular to an epoxy resin-type rebar-planting glue and a preparation process thereof. Background technique [0002] The planting glue has high bonding strength, like pre-embedding, curing at room temperature, small shrinkage during hardening, good temperature resistance, can be welded after embedding, good durability, weather resistance, aging resistance, and medium (acid, alkali, Water) has good performance, excellent toughness and impact resistance after curing, does not contain volatile solvents, and is non-toxic and environmentally friendly; [0003] The planting glue is cured at room temperature, with high strength, strong adhesion, good durability, good anti-aging and acid and alkali resistance, excellent water resistance and other medium resistance, and the proportion of A and B components is wide, which is convenient for on-site operation. Pre-embedded and re...
