preparation example Construction

[0031]The preparation method of composite pointing base material comprises the following steps:

[0032] (1) Mix pretreated reed leaves, acetic anhydride, and sodium bisulfite solution with a mass fraction of 15% at 35~55°C according to the mass ratio of 3:1:7~12, and stir at 400~700r / min for 40 ~60min, filter, take the filter cake and dry it in an oven at 60~75°C, crush it through a 100-mesh sieve, collect the sieved matter and add additives at a mass ratio of 5~8:1 to mix, and stir magnetically at 400~700r / min for 40~60min, get pre-processed material;

[0033] (2) Take methyl vinyl silicone rubber at a mass ratio of 50~80:12:5~8, add pretreated fly ash and castor oil, mix in an open mill for 20~35min, discharge, and cool naturally to room temperature to obtain The kneaded product, in parts by mass, takes 30~50 parts of kneaded product, 20~30 parts of muscovite, 5~10 parts of basalt fiber, 15~25 parts of pretreatment material, 0.1~0.3 part of Tairan enzyme, 3~ 7 parts of di...

Embodiment 1

[0037] Pretreatment of reed leaves: Take the reed leaves and crush them through a 80-mesh sieve in a pulverizer, collect the sieved particles and add 15% NaOH solution at a mass ratio of 1:8, mix and stir for 25 minutes, filter, wash the filter residue twice with water, and dry. To obtain the dried product, take the dried product and add 12% HCl solution at a mass ratio of 1:6 to mix, filter with suction, and dry the filter residue in a freeze dryer at -10°C for 5 hours to obtain pretreated reed leaves.

[0038] Additives: Mix trimethylhexadecylammonium bromide, sodium tripolyphosphate, and sodium citrate at a mass ratio of 4:3:1 to obtain the additive.

[0039] Pretreatment of fly ash: Take fly ash and 15% sodium bicarbonate solution at a mass ratio of 1:6, mix and stir for 25 minutes, filter, take the filter residue at a mass ratio of 15:1, add silane coupling agent KH-550 and mix Grind for 1 hour to obtain pretreated fly ash.

[0040] Chain extender: Mix 1,4-butanediol and...

Embodiment 2

[0050] Pretreatment of reed leaves: take reed leaves and crush them through a 80-mesh sieve in a pulverizer, collect the sieved particles and add 15% NaOH solution at a mass ratio of 1:13, mix and stir for 45 minutes, filter, wash the filter residue with water for 4 times, and dry. To obtain the dried product, take the dried product and add 12% HCl solution at a mass ratio of 1:10 to mix, filter with suction, and take the filter residue and dry it in a freeze dryer at -10°C for 8 hours to obtain pretreated reed leaves.

[0051] Additive: Mix trimethylhexadecylammonium bromide, sodium tripolyphosphate and sodium citrate at a mass ratio of 8:3:1 to obtain the additive.

[0052] Pretreatment of fly ash: Take fly ash and 15% sodium bicarbonate solution according to the mass ratio of 1:10, mix and stir for 45 minutes, filter, take the filter residue according to the mass ratio of 25:1, add silane coupling agent KH-550 and mix Grind for 3 hours to obtain pretreated fly ash.

Abstract

The invention discloses a waterproof grout for tiles, and belongs to the field of building materials. Reed leaves are subjected to crushing, refining, alkaline leaching and acid leaching treatment, added diatomite and sodium citrate provide adsorption and chelation effects to form a chelate together with calcium ions generated in the cement hydration process, and a soluble salt is effectively restrained from migrating to the surface, so the saltpetering phenomenon of a traditional grout is prevented; and a micro-block polymer with a surface active structure is prepared from polyether polyol, diphenylmethane diisocyanate and the like, and micelles formed around capillary pores disperse stress, so that migration of chloride ions, carbonate ions and the like in the capillary pores is effectively prevented, the chloride ion permeability resistance of the grout is remarkably improved, and the waterproof property is improved. The problems of poor waterproof property and high saltpetering tendency of existing common grouts are solved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a water-resistant grouting agent for ceramic tiles. Background technique [0002] With the continuous improvement of engineering construction quality and people's requirements for engineering details, the requirements for the quality of various fine parts of buildings have also been continuously paid attention to. It is this pursuit of the quality of architectural project details that fully guarantees the quality requirements of architectural projects in millimeters, and also makes joint leakage that often occurred in the past and the combination of various mixed materials The common problems in the construction industry, such as the cracking of the plaster layer, can be effectively solved. The emphasis on the details and quality of various parts of the building has also spawned the production and application of many new materials, and different types of jointing agents used in...
