Abstract

The invention discloses an antistatic bitumen waterproof sheet material, comprising the following raw materials in parts by weight: 82-90 parts of bitumen, 0.2-0.3 part of N,N-dihydroxyethyloctadecyl amine, 2-3 parts of cellulose acetate, 5-7 parts of vinylidene chloride resin, 2-3 parts of aluminum-magnesium silicate, 26-30 parts of attapulgite, 1-2 parts of anhydrous calcium chloride, 0.5-0.8 part of bisphenol A diglycidyl ether, 3-4 parts of T405 sulfurized olefin cotton oil, 30-40 parts of 6% NaOH solution, 6-10 parts of alkali lignin, 2-3 parts of epoxy chloropropane and 21-30 parts of machine oil. According to the antistatic bitumen waterproof sheet material, the alkali lignin is subjected to epoxidation process, so that the molecular crosslinking degree of the lignin is increased, so that the insulativity, mechanical property, thermostability, adhesiveness and preservative effect of the finished product can be effectively improved by adding the processed alkali lignin in to the resin system; both the vinylidene chloride resin and the N,N-dihydroxyethyloctadecyl amine have very good antistatic effect, so that construction safety of the finished product in some special fields can be ensured.

Description

A kind of antistatic asphalt water-proof coiled material

Technical field

The present invention relates generally to coiled material field, particularly relates to a kind of antistatic asphalt water-proof coiled material.

Background technology

Be immersed on carcass by pitch class or high score subclass water-proof material, the water-proof material product be made into, provides as coils, is called waterproof roll, is a kind of flexible sheet water-proof material.Waterproof roll is mainly used for the place such as construction wall, roofing and tunnel, highway, refuse landfill, play the flexible building material product of a kind of rollable one-tenth web-like resisting extraneous rainwater, underground water seepage, be connected as ne-leakage between engineering foundation with buildings, it is the first barrier of whole engineering waterproofing, vital effect is played to whole engineering, and pitch is the generally acknowledged material with better water resistance, but because protobitumen has low temperature crisp, the feature that high temperature trickling is anti-, aging resistance is poor, needs to be improved by technology.Technological improvement at present for waterproof mainly contains catalytic oxidized asphalt, polymer modified asphalt etc., and these method modification costs are higher, complex process, and exists along with the prolongation waterproof effect of time is poor, and what have is unfavorable for the defects such as construction.

Summary of the invention

The object of the invention is just to provide a kind of antistatic asphalt water-proof coiled material.

The present invention is achieved by the following technical solutions:

A kind of antistatic asphalt water-proof coiled material, it is made up of the raw material of following weight parts:

Pitch 82-90, octadecyldiethanol amine 0.2-0.3, rhodia 2-3, supervinyi chloride resin 5-7, neusilin 2-3, attapulgite 26-30, Calcium Chloride Powder Anhydrous 1-2, bis-phenol a diglycidylether 0.5-0.8, T405 sulfurized olefin cotton oil 3-4,6% NaOH solution 30-40, alkali lignin 6-10, epoxy chloropropane 2-3, machinery oil 21-30.

2, a preparation method for antistatic asphalt water-proof coiled material as claimed in claim 1, is characterized in that comprising the following steps:

(1) by rhodia, alkali lignin, octadecyldiethanol amine mixing, insulated and stirred 10-15 minute at 35-40 DEG C, add the NaOH solution of above-mentioned 6%, epoxy chloropropane is added after stirring, insulation reaction 4-5 hour at 80-85 DEG C, regulates PH to be 3-6 with 38% hydrochloric acid soln after cooling, decompress filter, drying, obtains epoxidation xylogen;

(2) bis-phenol a diglycidylether is joined in T405 sulfurized olefin cotton oil, supervinyi chloride resin, Calcium Chloride Powder Anhydrous is added after stirring, insulated and stirred 10-20 minute at 80-90 DEG C, add the 60-70% of above-mentioned machinery oil weight, epoxidation xylogen, raised temperature is 90-100 DEG C, insulated and stirred 40-50 minute, discharging cools, and obtains lignin resin binding agent;

(3) melted by asphalt heating, dehydration, add remaining machinery oil, adjustment temperature is 190-230 DEG C, adds lignin resin binding agent, insulated and stirred 20-30 minute, adds each raw material of residue, by colloidal mill grinding fully, obtains modifying asphalt batch mixing;
