Embodiment 1
[0019] A preparation method for high-insulation polymer concrete for power transmission pipelines, comprising the following steps:
[0020] 1) In parts by weight, add ordinary portland cement: 40 parts, wollastonite powder: 5 parts, mica powder: 10 parts, polycarboxylate superplasticizer: 0.1 part into a 250ml beaker, and use a glass rod Stir evenly, then add water: 10 parts, Deform W-098 water-based defoamer: 0.01 parts, styrene-acrylic emulsion: 10 parts into the beaker and stir evenly with a glass rod to obtain a mixed solution, which is flowing;
[0021] 2) Stir the mixture with a tetrafluoroethylene stirring rod, control the speed at 200r / min, and stir for 20 minutes. After the stirring is completed, pour the mixture into a watch glass and vibrate it with a glass rod for 2 minutes. The dish was placed in a curing box with a temperature of 20°C and a humidity of 95% for 8 days to obtain a sample block;
[0022] 3) The sample block was taken out from the curing box, and pl...
Embodiment 2
[0024] A preparation method for high-insulation polymer concrete for power transmission pipelines, comprising the following steps:
[0025] 1) In parts by weight, add slag portland cement: 35 parts, wollastonite powder: 8 parts, mica powder: 7 parts, HSB aliphatic superplasticizer: 0.05 parts into a 250ml beaker, and use a glass rod Stir evenly, then add water: 15 parts, Deform W-074 water-based defoamer: 0.015 parts, vinegar-acrylic emulsion: 20 parts into the beaker and stir evenly with a glass rod to obtain a mixed solution, which is fluid;
[0026] 2) Stir the mixture with a tetrafluoroethylene stirring rod, control the speed at 150r / min, and stir for 15 minutes. After the stirring is completed, pour the mixture into a watch glass and vibrate it with a glass rod for 1 min. The dishes were placed in a curing box with a temperature of 18°C and a humidity of 98% for 6 days to obtain samples;
[0027] 3) The sample block was taken out from the curing box, and placed under d...
Embodiment 3
[0029] 1) In parts by weight, add ordinary portland cement: 40 parts, wollastonite powder: 10 parts, mica powder: 10 parts, polycarboxylate superplasticizer: 0.15 parts into a 250ml beaker, and use a glass rod Stir evenly, then add water: 30 parts, Deform W-074 water-based defoamer: 0.02 parts, vinegar-acrylic emulsion: 25 parts into the beaker and stir evenly with a glass rod to obtain a mixed solution, which is flowing;
[0030] 2) Stir the mixture with a tetrafluoroethylene stirring rod, control the speed at 300r / min, and stir for 20 minutes. After the stirring is completed, pour the mixture into a watch glass and vibrate it with a glass rod for 2 minutes. The dish is placed in a curing box with a temperature of 20°C and a humidity of 99% for 10 days to obtain a sample block;
[0031] 3) The sample block was taken out from the curing box, and placed in a dry condition for 8 days to obtain a high-insulation polymer concrete C.
