Embodiment 1

[0025] The specific preparation process of the phase-change diatomite powder is as follows: 10g of myristyl alcohol and 22g of lauric acid are added to the stirring tank at the same time, the temperature in the stirring tank is controlled to be 10-15°C, and 5.3g of diatomite is added to it at the same time, and then the Vacuumize the stirred tank for 20-30min, then slowly raise the temperature to 50°C, control the heating rate to 1°C / min, heat it up to 50°C and keep it warm for 60-70min, then filter while it is hot, and then quickly put the solid into the 0-5°C Cool in the freezer, then add 10g of liquid phenolic resin and 2.3g of hexamethylenetetramine into the reaction vessel simultaneously, add 4.5g of the cooled solid thereinto at the same time, stir and mix at room temperature for 4-6min, then filter, and Dry and solidify the filtered solid at room temperature to obtain phase-change diatomite powder.

Embodiment 2

[0027] The specific preparation process of the phase-change diatomite powder is as follows: 10g of myristyl alcohol and 22g of lauric acid are added to the stirring tank at the same time, the temperature in the stirring tank is controlled to be 10-15°C, and 5.3g of diatomite is added to it at the same time, and then the Vacuumize the stirred tank for 20-30min, then slowly raise the temperature to 50°C, control the heating rate to 1°C / min, heat it up to 50°C and keep it warm for 60-70min, then filter while it is hot, and then quickly put the solid into the 0-5°C Cool in a freezer to obtain a phase-change diatomite powder.

Embodiment 3

[0029] The specific preparation process of the joint filler is as follows:

[0030] Step 1: Add urea and 2,5-dihydroxybenzaldehyde into the reaction vessel at a ratio of 1:2, and add water to the reaction vessel at the same time, then raise the temperature to 50°C and stir for 4 hours, then raise the temperature To 75°C, add isopropyl titanate into the reaction vessel, the amount of isopropyl titanate added is half of the amount of urea, stir and react for 3-4h, then filter, wash and dry to obtain tetraphenolic hydroxyl Titanate;

[0031] Step 2: Then add 10g of dried tetraphenol hydroxy titanate into 150mL of 1% dilute hydrochloric acid solution, add 13g of ethanedithiol to it at the same time, and then heat up to 80-85°C for reflux reaction for 20-22h , and then carry out vacuum distillation, and wash the obtained product to neutrality and then dry to obtain titanium phenol monomer;

[0032] Step 3: Add 10 g of the titanium phenolic monomer obtained in Step 2 into 120 mL o...

Abstract

The invention discloses waterproof type heat-insulating mortar. The waterproof type heat-insulating mortar comprises the following components in parts by weight: 20 to 25 parts of cement, 60 to 70 parts of fine river sand, 32 to 36 parts of phase-change diatomite powder, 3 to 4 parts of glass fiber, 6 to 8 parts of rubber powder, 5 to 6 parts of KN2066 heat-insulating rubber powder, 12 to 14 partsof joint sealing material and 28 to 32 parts of water. The joint sealing material and the rubber powder are added in the mortar; through addition of the rubber powder, the elastic strain performanceof concrete is improved and the condition that crack occurs on a roof due to the thermal expansion and cold shrinkage action under the high-temperature and high-cold conditions can be avoided; furthermore, after the joint sealing material is added and the concrete is paved, the joint sealing material is foamed slowly under the action of a foaming agent, so that concrete particle gap is filled witha foam plastic material formed after foaming to avoid clearance; and the foam plastic material after filling has a certain elastic deformation performance, so the high-temperature and high-cold deformation resistance of the roof can be further improved.

Description

technical field [0001] The invention belongs to the field of thermal insulation material preparation, and relates to a waterproof thermal insulation mortar and a construction process thereof. Background technique [0002] The top of the house on the top floor is directly exposed to sunlight and rainwater, resulting in cold winter and hot summer, and the roof is prone to leakage after long-term water accumulation. In order to solve the problem of cold winter and hot summer, a layer of thermal insulation mortar is usually laid on the roof to achieve heat preservation. Effect, the existing thermal insulation mortar usually adds porous ceramic material or porous glass material to the mortar material, and realizes the effect of phase change and heat preservation through the air stored in the pores of the porous material, but the phase change temperature is relatively high, and at the same time the mortar in the roof slab There is still a gap in the middle of the mortar material, ...
