preparation example Construction

[0038] The preparation method of the anti-cracking asphalt includes the following preparation steps:

[0039] Step 1: Take the asphalt of 1 / 2 ~ 2 / 3, add modified rubber powder, glue rubber, fully mixed, heating and stirring for a period of time, letting cool;

[0040] Step 2: Take the remaining part of the asphalt, add foamed plastic, glass fiber, stir mix;

[0041] Step 3: Mix the mixture obtained by step 1 and step 2, add anti-aging, antioxidants, and plasticizers, heating and stirring

[0042] Further, in the step 1, the heating temperature is 140-160 ° C, the stirring speed is from 200 to 3000 rpm / min, and the stirring time is 1-2 h.

Abstract

The invention provides an anti-cracking asphalt composed of the following components in parts by weight: 70 to 95 parts of asphalt, 5 to 10 parts of modified rubber powder, 5 to 10 parts of foamed plastic, 1 to 3 parts of skim rubber, 2 to 5 parts of glass fibers, 1 to 3 parts of an anti-aging agent, 0.5 to 1 part of an antioxidant and 0.5 to 1 part of a plasticizer. The prepared anti-cracking asphalt is low in cost, environment-friendly and simple to prepare.

Description

Technical field [0001] The present invention relates to the field of building, and more particularly to a anti-radic asphalt and a preparation method thereof. Background technique [0002] Asphalt is a viscous, black and has a highly viscosity liquid or a semi-solid form of petroleum, which is black, soluble in carbon sulfide, carbon tetrachloride. [0003] Asphalt can be divided into three kinds of coal tar asphalt, petroleum asphalt and natural asphalt: where the coaoco asphalt is a by-product of coking. Petroleum asphalt is the residue of crude oil fractionation. Natural asphalt is stored underground, and some form a mineral or accumulated on the surface of the crust. [0004] The main use of asphalt, about 70% of asphalt, is used in road construction, asphalt is used as glue or adhesive mixed with architectural aggregate particles to produce asphalt concrete. Other main purposes of asphalt are used for asphalt waterproof, including linoleum production and a flat roof seal. ...
