Abstract

The invention discloses a fast-drying, low-temperature type environmental-protection epoxy resin bicomponent dry coating, which consists of two components, namely A and B, and is characterized by: 1. 10 to 15 minutes of initial curing time at the temperature of 25 DEG C and 1 hour of fully curing time; 2. good anti-seismic property, anti-shock property, anti-aging property, anti-compression property, and waterproof property, moisture-proof property, anti-acid property, and the like; 3. high bonding strength, less influence of seasonal climate on construction thereof, being capable of being prepared on the condition of low temperature of minus 20 to minus 80 DEG C, non-hardening property in winter and thus overcoming the difficulty of construction in winter; 4. 30 to 45 minutes of surface drying time, thereby providing a reasonable construction period for construction; and 5. good toughness, non-brittleness, and being capable of preventing deformation, distortion, and falling-off caused by various external factors. The invention can be widely applicable to industries such as construction and decoration, machinery, metal and ceramics, leather and wood, furniture and footwear, and the like.

Description

technical field [0001] The invention relates to a stone bonding adhesive, in particular to a novel quick-drying, low-temperature environmental-friendly epoxy resin two-component dry-hanging adhesive. Background technique [0002] With the wide application of stone in construction, the market demand for stone adhesives continues to expand, especially in the bonding of stone and metal pendants, the maintenance and reinforcement of bridges and buildings, and the dry bonding construction of wall tiles. Glue is in great demand. Epoxy resin and curing agent are the main components of high-performance stone adhesive, and the auxiliary components include pigments, fillers, etc., among which the performance of epoxy resin is the main factor that determines the bonding performance. Epoxy resin is a thermosetting resin with an average of two or more epoxy groups per molecule. It is widely used in Adhesives, coatings, composite material substrates, etc. Due to the high cross-linking ...
