Embodiment 1

[0025] Embodiment 1 provides the producer of raw material in the embodiment

[0026] Proportioning (weight ratio, the same below) of creep type hot-melt rubber asphalt waterproof coating raw materials according to the following (Table 1):

[0027] Table 1 Creep-type hot-melt rubber asphalt waterproof coating formula table

[0028]

[0029] The manufacturing process of creep-type hot-melt rubber asphalt waterproof coating is as follows:

[0030] a. Heat the asphalt to 130-160°C for later use;

[0031] b. Add plasticizer and tackifying resin to asphalt at 130-160°C, stir at low speed for half an hour;

[0032] c. Increase the temperature to 180-200°C, add POE and ethylene-vinyl acetate copolymer, and start the colloid mill, and stir for about 1-2 hours until the modifier is completely melted;

[0033] d. Keep the temperature at 160-180°C, add filler and stir for 30-50 minutes until the particles are evenly dispersed;

[0034] e. Cool down to 140-160°C and discharge.

Embodiment 2

[0036] Proportioning (weight ratio, the same below) of creep type hot-melt rubber asphalt waterproof coating raw materials according to the following (Table 2):

[0037] Table 2 Creep-type hot-melt rubber asphalt waterproof coating formula table

[0038]

[0039]

[0040] The manufacturing process of the creep type hot-melt rubber asphalt waterproof coating in Example 2 is as in Example 1.

Embodiment 3

[0042] The raw materials of creep type hot melt rubber asphalt waterproof coating are proportioned according to the following (Table 3) (weight ratio, the same below):

[0043] Table 3 Creep-type hot-melt rubber asphalt waterproof coating formula table

[0044]

[0045] The manufacturing process of the creep type hot-melt rubber asphalt waterproof coating in Example 3 is as in Example 1.

Abstract

The invention discloses creep deformation type hot melt rubber asphalt waterproof paint, which has a high solid content (more than 99%), and good high temperature resistance, excellent low temperature flexibility, and better creep property. The paint can individually be used as a film waterproof layer, and can be compounded with polymer (SBS or APP) modified asphalt waterproof coiled materials for forming two waterproof layers for protection, and similar products employ thermoplastic elastomers (such as star SBS) and glue powder modifiers for modification of asphalt. The invention employs the new polyolefin elastomer modifier and the plastic modifier composite system, and compared with present non-solidification asphalt paint, the product has the advantages of better creep property and higher bonding intensity and better adaptability to facade construction requirements.

Description

technical field [0001] The invention relates to an asphalt-based waterproof paint, which is mainly used in various waterproof projects and can be used for waterproof construction alone or in combination with waterproof coiled materials. technical background [0002] Domestic modified asphalt coatings are mainly solvent-based and water-emulsion modified asphalt waterproof coatings. In the process of use, there are different degrees of defects, especially in poorly ventilated kitchens and bathrooms and buildings. One is to prolong the construction period. The cycle of operation, the second is the health impact on the workers. In order to change this situation, a creep-type hot-melt rubber asphalt waterproof coating has been developed, which has a high solid content (above 99%), good high temperature resistance, excellent low temperature flexibility, and better creep properties. [0003] Creep-type hot-melt rubber asphalt waterproof coating can be used alone as a film waterpro...
