example 1

[0020]Mix sodium hydroxide and magnesium chloride hexahydrate in a beaker at a mass ratio of 1:4, and add water 30 times the mass of sodium hydroxide and a mixture of sodium lauryl sulfate 0.6 times the mass of sodium hydroxide to the beaker. After stirring and mixing for 60 minutes under the condition of 65°C and 1200r / min, the aqueous phase mixture was obtained; acrylonitrile and methyl acrylate were mixed in the flask at a mass ratio of 3:1, and 0.2 mass of acrylonitrile was added to the flask. times vinyl acetate, isopentane 0.4 times the mass of acrylonitrile, azobisisobutyronitrile 0.05 times the mass of acrylonitrile and ethylene glycol dimethacrylate 0.02 times the mass of acrylonitrile, at a temperature of 55°C, After stirring and mixing for 60 minutes at a rotation speed of 1000r / min, an oil phase mixture was obtained. Mix the oil phase mixture and the water phase mixture at a mass ratio of 1:3, and stir and mix at a temperature of 65°C and a rotation speed of 1200r / m...

[0022] Mix sodium hydroxide and magnesium chloride hexahydrate in a beaker at a mass ratio of 1:4, and add water 30 times the mass of sodium hydroxide and a mixture of sodium lauryl sulfate 0.6 times the mass of sodium hydroxide to the beaker. After stirring and mixing for 60 minutes at 65°C and 1200r / min, the aqueous phase mixture was obtained; the pretreated chitin and water were mixed at a mass ratio of 1:260, and the pretreatment was adjusted with acetic acid with a mass dispersion of 20%. The mixture of chitin and water has a pH of 4, ultrasonically disperses at a frequency of 50 kHz for 25 minutes, centrifuges, and takes the upper layer to obtain a chitin fiber dispersion; mix the chitin fiber dispersion with chitosan solution Mix in a conical flask at a mass ratio of 1:5, stir and mix for 2 hours at a temperature of 55°C and a speed of 400r / min to obtain a chitin-chitosan mixture, and mix the chitin-chitosan mixture with Anhydrous ethanol was mixed in a three-necked fla...

Abstract

The invention discloses a thermal insulation caulking agent, which belongs to the technical field of building materials. In parts by weight, weigh in turn: 200-300 parts of cement, 300-400 parts of quartz sand, 20-30 parts of heavy calcium carbonate, 10-15 parts of redispersible latex powder, hydroxypropyl methylcellulose 1 ~3 parts, 30~50 parts of modified gel and 5~10 parts of surfactant, mix cement and quartz sand in a mixer, and add heavy calcium carbonate, redispersible latex powder, hydroxypropyl Methyl cellulose, modified gel and surfactant are stirred and mixed for 20 to 30 minutes at a temperature of 40 to 60°C and a rotational speed of 300 to 600 r / min to obtain a thermal insulation sealant. The thermal insulation sealant prepared by the technical scheme of the invention has the characteristics of excellent thermal insulation performance and crack resistance, and has broad prospects in the development of the building material industry.

Description

technical field [0001] The invention discloses a thermal insulation caulking agent, which belongs to the technical field of building materials. Background technique [0002] The caulking agent has the characteristics of strong adhesion, small shrinkage, strong color fixation, anti-crack flexibility, good decorative texture, pressure resistance, wear resistance, and mold resistance, making it perfect for repairing cracks or damage on the floor surface. The surface can also be painted and is waterproof. Ceramic tiles have become the main building materials in modern buildings and are widely used in the decoration of the interior and exterior walls and floors of buildings. Ordinary buildings use cement fine sand and water to make cement mortar and use it as a joint sealant. The common shortcomings of this kind of joint sealant mixed with ordinary cement and water in construction are low adhesion, fast hardening time, and short-term use. If it is not finished, the sealant will...
