CN102031002A - Non-cured asphalt mastic - Google Patents

Abstract

The invention requests to protect non-cured asphalt mastic comprising the following components in percentage by weight: 35-55 asphalt, 15-30 naphthenic oil, 3-10 polymer modifying agent, 55-20 gelatin powder, 3-10 diisononyl phthalate and 10-20 tackifying resin. The non-cured asphalt mastic can be independently used or can be used with the matched coil to form a waterproof system and can effectively solve the problem of water leakage caused by the crack of a waterproof layer due to the deformation of a base layer.

Description

Non-curing pitch glue

Technical field:

The present invention relates to a kind of non-curing pitch glue, particularly a kind of non-curing rubber pitch glue that is applied to the building structure waterproofing work.

Background technology:

Asphalt water-proof coiled material is because its technology maturation, industrialized level height, stable performance, and easy construction safeguards that facility are simple, uses very extensive at home and abroad during therefore worker China Democratic National Construction Association establishes.Asphalt water-proof coiled material (abbreviation asphalt felt) is that one deck is laid on building surface, or the waterproof layer between building basal plane and the decorative cover, can play building waterproof, moisture-proof role, be the important technical that improves the building waterproof performance and increase the service life.Asphalt water-proof coiled material because simple in structure, the maintenance amount is few, long service life, once construction can reach characteristics such as permanent waterproof effect, thereby at home and abroad generally adopt in the civil building.Though existing asphalt water-proof coiled material also possesses certain extension property, when crack or building structure appearance distortion appear in the building basal plane, still cause waterproof layer cracking easily.And, in baroque zone, be difficult to accomplish completely sticking, thereby causing going here and there the water phenomenon takes place.

Non-curing rubber pitch glue can solve the problems referred to above, and this material uses with supporting coiled material, constitutes a cover waterproof system, can effectively solve the waterproof layer cracking problem that phenomenons such as building basic unit's distortion causes.This material has creep property and self-healing performance, and does not also solidify after air contacts for a long time, can forever keep the elastoplasticity colloid.

Summary of the invention:

The present invention aims to provide a kind of waterproof material---non-curing rubber pitch glue, non-curing pitch glue provided by the present invention, contain following component by percentage to the quality:

Pitch 35%-55%;

Naphthenic oil 15%-30%

Polymer modifiers 3%-10%

Rubber powder 5%-20%

Diisononyl phthalate 3%-10%

Tackifying resin 10%-20%

Described non-curing pitch glue preferably contains following component by percentage to the quality:

Pitch 38%-52%;

Naphthenic oil 18%-26%

Polymer modifiers 4%-9%

Rubber powder 6%-18%

Diisononyl phthalate 4%-8%

Tackifying resin 12%-19%

Described pitch is the 90# heavy traffic paving asphalt.

Used polymer modifiers comprises SBS, SBR, SIS, APP etc., and tackifying resin comprises coumarone indene resin, terpine resin, hydrogenated petroleum resin etc.

The present invention also provides the technology of the described non-curing pitch glue of preparation, and it comprises the steps:

(1) pitch is heated to 130 ℃-160 ℃, the metering back is standby;

(2) naphthenic oil, tackifying resin are joined in 130 ℃-160 ℃ the pitch, open stirring at low speed simultaneously, controlled temperature is 130 ℃-160 ℃, stirs half an hour;

(3) be warmed up to 160 ℃-200 ℃, add polymer modifiers, and open colloidal mill, stirred 1-2 hour, do not have visible particle to naked eyes;

(4) add diisononyl phthalate and rubber powder, stir discharging after 1 hour.

Non-curing pitch glue provided by the present invention possesses following characteristics and advantage:

Never solidify, solid content is greater than 99%, and VOC free is environment friendly and pollution-free;

Good stability, high-low temperature resistant, acid and alkali-resistance brine corrosion;

Adhesiveproperties is good, all can be completely sticking with various material basic unit, can effectively prevent to go here and there the water phenomenon;

Self-healing property is strong, also can repair the crack that waterproof layer occurs voluntarily even building structure deforms;

Can use simultaneously with other water-proof materials, form complex waterproof layer, compatible good.

Embodiment:

Below by the non-limiting example the present invention that further explains, all belong to following scope, all belong to protection scope of the present invention.

Used polymer modifiers comprises SBS, SBR, SIS, APP etc., and tackifying resin comprises coumarone indene resin, terpine resin, hydrogenated petroleum resin etc.
