Abstract

The present invention provides asphalt adhesive paint, which relates to a paint composition of asphalt materials. The paint composition is prepared from rubber powder or wood powder, asphalt, engine oil and fly ash. During production, the asphalt is heated to the melting form, and then the rubber powder or the wood powder, the engine oil and the fly ash are added to be stirred. The paint composition has the characteristics that the production and the processing are convenient, old articles and leftovers can be utilized, the pollution can be reduced, the waterproofing and antifreezing effect is good, and the paint composition is free from the influence of hot and cold weather in construction.

Description

Mastic paint

The invention belongs to coating composition, particularly the coating composition of bituminous material.

Disclose a kind of " bentonite emulsified asphalt water-proof paint " on July 2nd, 97 No. 27 " Gazette of Patent for Invention ", its application number is 96111465.7, publication number is CN1153194A, this coating is made up of asphalt base-material 35---55%, wilkinite 6---20%, water 34---50%, need during processing at first asphalt base-material to be heated to 160---220 ℃, water also need be heated to 85---100 ℃, also need add certain wilkinite, issue after examination and approval existing this project technology following shortcoming is arranged through returning retrial: 1) process for processing complexity; 2) used asphalt base-material must be used first-class pitch, otherwise its quality product is very poor; 3) be difficult for cold construction, the construction back is difficult for joining to construction surface, and water resistance is poor.

The objective of the invention is to: produce a kind of waterproof, antifreeze, cheap mastic paint.

The present invention is made up of rubber powder or wood powder, pitch, machine oil and flyash, and wherein rubber powder, machine oil can be with tankage or waste Crumb rubber, used oil, pitch, also available useless pitch, crude oil or pyrobitumen.

The production blending ratio is: rubber powder 5---70% or wood powder 5---70%

Machine oil 5---60%

Pitch 20---80%

Flyash 8---60%

Above-mentioned per-cent sum should be 100%

During process for processing, at first pitch is heated to molten state, add interior stirring of pitch with other three kinds then and get final product.

The present invention compared with prior art, 1, easy to process, need not too many equipment; 2, this product can use old and useless article, makes some useless tankage, and row goes up use once more, has reduced environmental pollution, and product price is cheap; 3, test by returning retrial, waterproof, antifreezing effect are very good; 4, cold and hot weather construction can be not influenced.

Produce two examples:

Example 1 is got 30% pitch, is heated to molten, adds waste Crumb rubber 25% then, and used oil 30% and flyash 15% stir.

Example 2 is got pyrobitumen 55%, is heated to molten, adds wood powder 15% then, and machine oil 12% and flyash 18% stir.

Claims (2)

1, a kind of mastic paint, it is characterized in that: it is made up of rubber powder 5--70% or wood powder 5--70%, pitch 20--80%, machine oil 5--60% and flyash 8--60%, above-mentioned per-cent sum should be 100%, during production pitch is heated to molten, will adds rubber powder or wood powder, machine oil and flyash then again and stir.

2, coating according to claim 1 is characterized in that: rubber powder, pitch, machine oil can be with junk or tankage.
