Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] The present invention is realized in this way. The components of a non-curing rubber asphalt waterproof coating and their mass ratios are: 10%-15% of asphalt, 5%-15% of waste rubber powder, 24%-45% of softener, polymer Polymer 5%-10%, special additive 4%-10%, auxiliary agent 0.05%-1%, filler 20%-30%.

[0036] Further, the asphalt is selected from heavy traffic 90# asphalt, 10# asphalt or a mixture thereof.

[0037] Further, the waste rubber powder is 60-80 mesh tire tread rubber powder.

[0038] Further, the softening agent is one or a mixture of naphthenic oil, aromatic oil, and three-lin...

Abstract

The invention discloses a non-cured rubber asphalt waterproof paint. The preparation technology of the paint comprises the following steps: heating the asphalt to 140 DEG C, loading the heated asphalt into a stirring tank, adding a softening agent, rubber powder, and polymer, stirring for 30 minutes, heating to 160 DEG C, delivering the mixture to a colloid mill to grind the two edges, heating to 190 DEG C, adding a special additive, stirring for one hour, cooling to 160 to 170 DEG C, adding an auxiliary agent, stirring for one hour, adding a filling material, stirring for one hour, and finally discharging. The paint solves the problems of waterproof layer fracture due to the cracking stress, which is transferred from the basic layer to the waterproof layer, and the accelerated aging due to the flexural fatigue and high stress state of the waterproof layer. Moreover, because of the cohesiveness of the paint, the capillary pores and cracks in the basic layer can be perfectly sealed by the paint, thus the problem of water leaking in the waterproof layer is solved, and the waterproof reliability is greatly improved.

Description

technical field [0001] The invention belongs to the field of waterproof coatings, in particular to a non-cured rubber asphalt waterproof coating. Background technique [0002] Leakage of building structures has been a problem that has plagued the construction industry for a long time. Building waterproof technology and waterproof materials have always been an important topic for researchers to study. The situation of building leakage in our country is alarming and severe. [0003] The existing waterproof materials and waterproof construction technology have the following problems: Rigid waterproof materials are easily affected by the deformation of the base layer, resulting in cracking of the waterproof layer, which directly affects its waterproof function; during the use of flexible waterproof materials, the base surface is damaged due to construction or external forces. Or the waterproof material is damaged, which will lead to water ingress between the waterproof layer an...
