Embodiment 18

[0028] The difference from Example 1 is that the latex powder 1410 is replaced by the latex powder prepared by the following method: adjustment contains cetyltrimethylammonium bromide 0.9Kg, azobisisobutylamidine hydrochloride 0.5Kg and The pH value of the mixture of 280Kg of deionized water is 7.0, add 20Kg of styrene and 1.5Kg of methacryloxypropyltrimethoxysilane and pre-emulsify, stir the pre-emulsion in a nitrogen atmosphere and raise the temperature to 60°C and keep it warm React for 6 hours; lower to room temperature and adjust the pH value to 3.0, add 17.5Kg of tetraethyl orthosilicate, stir for 12 hours, and leave to age for 36 hours; add 22.5Kg of an aqueous solution of polyvinyl alcohol with a concentration of 5% by weight and mix Uniform, spray-dried to obtain latex powder.

Embodiment 19

[0030] The difference from Example 1 is that the latex powder 1410 is replaced by the latex powder prepared by the following method: adjustment contains cetyltrimethylammonium bromide 1.2Kg, azobisisobutylamidine hydrochloride 0.4Kg and The pH value of the mixture of 290Kg of deionized water is 6.9, add 17.5Kg of styrene and 2Kg of methacryloxypropyltrimethoxysilane and pre-emulsify, stir the pre-emulsion in a nitrogen atmosphere and raise the temperature to 65°C and keep it warm React for 5.5 hours; lower to room temperature and adjust the pH value to 2.9, add 20Kg of tetraethyl orthosilicate, stir for 24 hours, and leave to age for 42 hours; add 25Kg of an aqueous solution of polyvinyl alcohol with a concentration of 1% by weight and mix well , to obtain latex powder by spray drying.

Embodiment 20

[0032] The difference from Example 1 is that the latex powder 1410 is replaced by the latex powder prepared by the following method: adjustment contains cetyltrimethylammonium bromide 1.5Kg, azobisisobutylamidine hydrochloride 0.3Kg and The pH value of the mixed solution of 300Kg of deionized water is 7.1, add 15Kg of styrene and 1.75Kg of methacryloxypropyltrimethoxysilane and pre-emulsify, stir the pre-emulsion in a nitrogen atmosphere and raise the temperature to 70°C and keep it warm React for 5 hours; lower to room temperature and adjust the pH value to 3.1, add 15Kg of tetraethyl orthosilicate, stir for 18 hours, and leave to age for 48 hours; add 24Kg of an aqueous solution of polyvinyl alcohol with a concentration of 10% by weight and mix well, Latex powder was obtained by spray drying.

Abstract

The invention relates to a tile adhesive. The tile adhesive is characterized by comprising, by mass, 330-360 parts of alpha-type semi-hydrated gypsum, 620-680 parts of quartz sand, 10-15 parts of latex powder, 1-3 parts of citric acid, 2-4 parts of hydroxypropyl methyl cellulose, 1-3 parts of a defoaming agent and 1-3 parts of a wetting dispersant. The tile adhesive is prepared with the alpha-typesemi-hydrated gypsum which replaces cement, and can be well attached to the surfaces of a plurality of base materials hard to attach; the bonding strength is still very good under the condition of soaking in water, high temperate or freeze-thaw action.

Description

technical field [0001] The invention relates to the technical field of building materials, more specifically, it relates to a ceramic tile adhesive. Background technique [0002] Tile adhesive is a cement-based bonding material for pasting tiles. It is also known as tile adhesive. It is one of the most important varieties of dry-mixed mortar. It is the most commonly used bonding material in construction and decoration engineering. It can be used for pasting ceramic tiles, polishing Brick and natural stone such as granite. Traditionally, tile adhesives consist of aggregates, Portland cement, a small amount of slaked lime and functional additives according to product quality levels. However, there are huge energy consumption, consumption of non-renewable resources and environmental pollution in cement production, and people are gradually looking for substitutes for cement. [0003] The invention develops a ceramic tile adhesive prepared by using α-type hemihydrate gypsum ins...
