Embodiment 1

[0056] 40 kg of water, 5 kg of glutinous rice, 6.5 kg of polyvinyl alcohol, 0.5 kg of dioctyl phthalate, and 48 kg of ethylene-vinyl acetate emulsion.

[0057] Put glutinous rice and water into the reaction kettle and stir, add polyvinyl alcohol to boil and dissolve, stir to form a paste, add ethylene-vinyl acetate emulsion when the temperature is cooled to normal temperature, stir evenly, and finally filter to obtain biological waterproof glue.

[0058] The biological waterproof glue of the invention can be used for waterproofing, moisture-proofing and anticorrosion of wood; for anticorrosion of metal; and as a bonding agent for ceramics, glass and plastic products.

Embodiment 2

[0060] 16 kg of water, 1.5 kg of glutinous rice, 35 kg of acrylic acid emulsion, 7 kg of dioctyl phthalate, 15 kg of light calcium carbonate, 1.3 kg of polyvinyl alcohol, and 24.2 kg of ethylene-vinyl acetate emulsion.

[0061] Put glutinous rice and water into the reaction kettle and stir, add polyvinyl alcohol to boil and dissolve, stir to form a paste, add ethylene-vinyl acetate emulsion, dioctyl phthalate, acrylic acid emulsion and light The calcium carbonate raw material is stirred evenly at high speed, and finally filtered to obtain biological waterproof glue.

[0062] The biological waterproof glue of the present invention can be used for waterproofing of cement roofs, exterior walls, bathrooms, and basements in houses; for wood waterproofing, moisture-proofing, and anticorrosion; for repairing cracks in ointment, asphalt, and cement surfaces.

Embodiment 3

[0064] 40 kg of water, 5 kg of glutinous rice, 6.5 kg of polyvinyl alcohol, 0.5 kg of dioctyl phthalate, 35 kg of natural rubber powder, and 13 kg of ethylene-vinyl acetate emulsion.

[0065] Put the glutinous rice and water into the reaction kettle and stir, add polyvinyl alcohol and boil to dissolve, stir for about 5 hours to get a paste, add natural rubber powder when the temperature drops to about 30°C, stir at high speed for about 30 minutes, then add ethylene - Vinyl acetate emulsion, dioctyl phthalate, stirred evenly at high speed, and finally filtered to obtain biological waterproof glue.

[0066] The biological waterproof glue of the present invention can be used for waterproofing of cement roofs, exterior walls, bathrooms, and basements in houses.

Abstract

A biologic water-proof adhesive for building, wood, metal, ceramic, glass, etc is prepared from glutinous rice, water, ethene-vinyl acetate emulsion, dioctyl phthalate, PVC, tung oil, acrylic emulsion and natural rubber. Its advantages are high weatherability, adhesion, tension strength, elongation percentage for breaking and resistance to water, acid and alkali.

Description

technical field [0001] The invention belongs to the field of waterproof coatings, in particular to biological waterproof glue and its application. Background technique [0002] At present, ointment and asphalt materials are mostly used to repair cracks on cement pavement in China, but from the perspective of use effect, their waterproof effect is poor, so that the roadbed cannot be protected for a long time; waterproof membranes used for roof waterproofing include LHG, APP, SBS, ZYP, etc., paint waterproof series include LIP, IS, BR, JS, etc., but these waterproof materials are not easy to construct and difficult to operate in the complex parts of the construction, and there are natural weathering of waterproof materials, cracks are not durable, and water resistance is poor. Due to the large temperature changes, after several freeze-thaw cycles, the substrate and the substrate are easily separated, resulting in hollowing, joints are easy to crack, and there are many water ba...
