[0028] According to the mass ratio of 1:30, mix linseed oil and 6% gelatin solution into a beaker, and move the beaker into an ultrasonic disperser, and ultrasonically disperse for 60 minutes at an ultrasonic frequency of 55 kHz and a temperature of 50 °C. To obtain the emulsion, add 10% of the emulsion mass to a beaker with a 20% sodium sulfate solution, then heat, stir and mix for 4 hours at a temperature of 90°C and a rotational speed of 500r / min, stop heating, and cool down to 60 ℃, then add 10% of the emulsion mass fraction in the beaker and formaldehyde solution with a mass fraction of 37%, and adjust the pH of the material in the beaker to 9.4, stir and mix with a glass rod for 15 minutes, stand and solidify for 460 minutes, and then filter with suction to obtain a filter cake , and wash the filter cake with deionized water for 5 times, then freeze-dry the washed filter cake to obtain linseed oil microcapsules; pulverize the sepiolite and pass through a 300-mesh sieve to...

Abstract

The invention discloses a dual-component room-temperature cured type waterproof building adhesive and belongs to the technical field of adhesives. The dual-component room-temperature cured type waterproof building adhesive disclosed by the invention is prepared from a component A and a component B, wherein the component A is prepared from epoxy resin, modified unsaturated polyester resin, linseedoil microcapsule and filler; the component B is prepared from a curing agent, a coupling agent and an accelerating agent; the filler is prepared from graphene oxide, modified sea-foam stone powder andmodified microcrystalline cellulose; the component A and the component B are separately packaged to form the dual-component room-temperature cured type waterproof building adhesive. The dual-component room-temperature cured type waterproof building adhesive disclosed by the invention has excellent waterproofness.

Description

technical field [0001] The invention discloses a two-component room temperature curing water-resistant construction adhesive, which belongs to the technical field of adhesives. Background technique [0002] Construction glue is a type of glue, which is widely used in construction engineering and is an indispensable material in construction engineering. It can also be used for road signs, dam leak prevention, and military engineering emergency maintenance. Construction adhesives are used in every process and even every material in the construction industry. Building sealing glue is mainly used for sealing various seams or holes in buildings to prevent gas, liquid and solid from penetrating, and to prevent structural materials from being damaged when the structure is displaced, so as to achieve heat preservation, sound insulation, waterproof, dustproof, Gas-proof, fire-proof, anti-corrosion, shock-absorbing and preventing the accumulation of foreign matter in the joints. Th...
