Standard is carried out according to JC/T2428-2017, and test result is as shown in table 1.
3 properties of product testing result of 1. embodiment 2 of table and embodiment
By above-mentioned all-round property testing result relatively known to: the embodiment of the present invention 2 and embodiment 3 are of the invention excellent
Apolegamy side, the ductility of water-repellent paint prepared by the present invention, caking property, weatherability and self-healing property are preferable.
The present invention has developed a kind of with comprehensive performance according to many years research, knowhow and professional knowledge abundant
It is good, production cost is low and VOC content is extremely low uncured rubber asphalt waterproof coating, it can be achieved that said effect formulation for coating material
Are as follows:
44-54 parts of this pitch, 15-25 parts of naphthenic oil, 2-5 parts of modifier A, 3-6 parts of modifying agent B, modifying agent C 3-6
Part, 2-4 parts of rosin resin, 5-10 parts of SBR, 10-20 parts of coarse whiting, 1-2 parts of antioxidant, 2-4 parts of thickener；Wherein, the modification
Agent A modified polypropylene waxes H430.
By experimental verification, further preferably it is formulated are as follows: 46-52 parts of pitch, 16-20 parts of naphthenic oil, modifier A 3-4
Part, 3-4 parts of modifying agent B, 4-5 parts of modifying agent C, 2-3 parts of rosin resin, 5-8 parts of SBR, 10-15 parts of coarse whiting, 2 parts of antioxidant,
2-3 parts of thickener.
The performance comparison of 1-4 is it is found that the coating comprehensive performance of embodiment 2 and embodiment 3 is more preferable through the foregoing embodiment,
Most preferably it is formulated are as follows: 48-50 parts of pitch, 16-18 parts of naphthenic oil, 3-4 parts of modifier A, 3-4 parts of modifying agent B, modifying agent C 4-5
Part, 2 parts of rosin resin, 5-6 parts of SBR, 12 parts of coarse whiting, 1.5 parts of antioxidant, 2 parts of thickener.
The present invention selects specific modifier A (modified polypropylene waxes H430), compared to traditional manufacturing technique use into
Mouth polyethylene wax (such as Honeywell AC-325 or 8903), modified polypropylene waxes can more improve the soft of uncured water-repellent paint
Change point, reduce mobility, significantly improve heat resistance, while cost has and significantly reduces.
The present invention selects specific modifying agent B (linear phenylacetic acid-isoprene styrene thermoplastic block copolymers
S1105) modified pitch has excellent resistance to ag(e)ing and excellent high temperature performance, compared to SBS, acts on uncured anti-
When in water paint, there is smaller cohesive force, so that croop property is more excellent, and reduces costs.
The present invention select specific modifying agent C (linear polyisobutene) can improve the resistance to ag(e)ing of rubber asphalt, weatherability,
Resist bending breaking property, ozone resistants reduce its absorption to water and the infiltration to gas, improve stickiness creep properties.
It is main that uncured rubber asphalt waterproof coating of the invention, which is with pitch and special additive (modifier A/B/C),
Raw material keeps a kind of waterproof material with creep properties of stickiness body of paste for a long time under application state；The coating can seal
Basic crack and pore are closed, complicated operation side is adapted to；Do not solidify for a long time after contacting with the air, remains sticky
The characteristic of colloid, self-healing ability is strong, touches and glues, is difficult to remove, and still has good adhesive property at -25 DEG C.Of the invention
Uncured rubber asphalt glue material does not also solidify after having croop property and self-healing performance, with air Long Term Contact, can permanently protect
Hold elastoplasticity colloid.Uncured rubber asphalt rubber of the invention is used together with matched coiled material, constitutes a set of waterproof system,
The caused waterproof layer cracking problem of phenomena such as can effectively solve the deformation of building base.Prepared by formula and method through the invention
Water-repellent paint has excellent comprehensive performance, and production cost is relatively low, VOC content decline.
Place, those skilled in the art can not select from the prior art to the greatest extent in the embodiment of the present invention.
Disclosed above is only a specific embodiment of the invention, but scope of protection of the present invention is not limited thereto, is appointed
What those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, answer
It is included within the scope of the present invention.Therefore, protection scope of the present invention should be with above-mentioned scope of protection of the claims
It is quasi-.
