Embodiment 1～3

[0030] Each substance added in Examples 1 to 3 is added as shown in Table 1 below;

[0031] Table 1 (parts by weight)

[0032]

[0033]

[0034] Table 2 (mass ratio)

[0035] Item Number thermoplastic styrene butadiene rubber powder polystyrene butadiene copolymer Example 1 1 0.6 Example 2 1 0.5 Example 3 1 1

[0036] Preparation method in embodiment 1~3 carries out according to the following steps:

[0037] 1. Calculated by 100 parts by weight: Weigh the asphalt and softened oil in turn, heat and melt, continue to heat to between 140°C and 150°C, and stir at 700rad / min for 15min;

[0038] 2. Slowly add the high-temperature agent, keep the temperature constant, stir at 700rad / min for 15min, then stir at 1000rad / min for 45min, observe whether the melting is complete, and proceed to the next step after no obvious particles

[0039] 3. Reduce the stirring to 700rad / min, add a thickener, and stir at 700rad / min for 30min;

Abstract

The invention discloses a high-performance non-cured asphalt waterproof material which is prepared from the following components in parts by weight: 40-45 parts of asphalt, 15-20 parts of softening oil, 4.5-5.5 parts of a high-temperature agent, 0.5-2 parts of a tackifier and 30-35 parts of a filler, wherein the high-temperature agent is a mixed particle material obtained by compounding a special compound modifier with thermoplastic styrene-butadiene rubber powder and a polystyrene-butadiene copolymer in a mass ratio of 1: (0.5-1). Compared with an existing non-curing waterproof coating, the preparation method of the coating is simpler and more convenient in preparation process, higher in product performance, better in stability, lower in energy consumption and more environmentally friendly.

Description

technical field [0001] The application relates to the technical field of waterproof coatings, in particular to a high-performance non-curing asphalt waterproof coating. Background technique [0002] The non-curing waterproof coating has the characteristics of superior non-curing, creep and self-healing properties. The coating can close the cracks and capillary pores of the base layer, and can adapt to complex construction work surfaces. The characteristics of colloid, strong self-healing ability, sticky when touched, difficult to peel off, and strong adhesion ability. It still has good bonding performance at -20°C. This type can solve the problems of waterproof layer fracture, flexural fatigue or premature aging under high stress state caused by the cracking stress of the base layer transmitted to the waterproof layer; at the same time, the viscosity of the creep material makes it well sealed The capillary pores and cracks in the base layer solve the problem of water chann...
