Effect test

Embodiment 1

[0025] Stir 50 parts of heavy calcium carbonate at 75°C, add 1 part of aluminate coupling agent, continue stirring for 30-60 minutes, and obtain aluminate modified heavy calcium carbonate after cooling.

Embodiment 2

[0027] Stir 75 parts of heavy calcium carbonate at 85°C, add 1 part of aluminate coupling agent, continue stirring for 30-60 minutes, and obtain aluminate modified heavy calcium carbonate after cooling.

Embodiment 3

[0029] Stir 100 parts of heavy calcium carbonate at 80°C, add 1 part of aluminate coupling agent, continue stirring for 30-60 minutes, and obtain aluminate modified heavy calcium carbonate after cooling.

[0030] 2. Determination of activation rate

[0031] Take by weighing 5g of the aluminate-modified heavy calcium carbonate described in Example 1-3, its mass is recorded as m, put in a 250mL separatory funnel, add 200mL of water, shake for 5min, then place on the funnel stand, Stand still for 30 minutes, after the obvious stratification, put the sinking calcium carbonate into the crucible filter which has been dried to constant weight at one time, remove the water by suction filtration, move into the constant temperature box, and dry to constant weight. The activation rate is represented by mass percentage, denoted as AD, and the specific calculation is: AD=(1-(m2-m1) / m)×100%, wherein: m2 is the mass (g) of the crucible and uncoated calcium carbonate after drying ; m1 is the...

Abstract

The invention provides a smokeless non-cured rubber asphalt waterproof coating capable of being constructed at low temperature and a preparation method of the coating, and belongs to the technical field of asphalt waterproof coatings. The smokeless non-cured rubber asphalt waterproof coating is prepared from the following raw materials in percentage by weight: 25 to 40 percent of petroleum asphalt, 15 to 35 percent of oil, 5 to 12 percent of rubber modifier, 2 to 10 percent of high-temperature modifier, 2 to 5 percent of rosin resin and 10 to 35 percent of filler, wherein the filler is aluminate modified heavy calcium carbonate. The viscosity of the product is reduced, low-temperature construction is achieved, no smoke is generated during construction, and safety, energy conservation and environmental protection are achieved; and the bonding strength of the product can be improved, and the aging resistance of the product is improved.

Description

technical field [0001] The invention relates to the technical field of asphalt waterproof coatings, in particular to a smokeless non-curing rubber asphalt waterproof coating capable of low-temperature construction and a manufacturing method thereof. Background technique [0002] Non-curing rubber asphalt waterproof coating is a waterproof coating that maintains a viscous paste within the service life and is made of rubber, asphalt, and softening oil as the main components, adding a temperature control agent and a filler; this coating can remain viscous all the time Colloidal state, without forming a coating film, can close the cracks and capillary pores of the base layer, so it can adapt to complex construction work surfaces; and it will not solidify for a long time after contacting with the air, and always maintain the characteristics of viscous colloid, strong self-healing ability, impact resistance Adhesive to the touch, difficult to peel off, and still has good bonding p...
