Abstract

The invention relates to a sealing adhesive. The sealing adhesive is characterized by being prepared from toluene, petroleum pitch, dibutyl phthalate, zinc oxide, chloroprene rubber, stearic acid, tetramethylthiuram disulfide and magnesium oxide. The sealing adhesive has relatively good weather resistance, can be adapted to dramatic changes in ambient temperature between cold and hot and has a good sealing effect. The sealing adhesive is suitable for preventing water leakage sealing at seams of building members and the seams of plates.

Description

A kind of seal gum

Technical field

The present invention relates to a kind of sizing agent.Specifically, the seal gum preventing building slab seam crossing and sheet material seam crossing from leaking is used to.

Background technology

All knowing at building field, for avoiding water pipe head place to leak, after being usually wrapped with rubber film in the male joint of water pipe head place, then male joint being screwed in male joint.And the sealing between sheet material is mostly adopt epoxy resin glue.Although adopt rubber film and epoxy resin glue can realize the sealing of water pipe head and sheet material seam crossing respectively, the weather resistance of these two kinds of sealing materials is poor, and be difficult to the acute variation adapting to envrionment temperature between h and c, sealing effectiveness is poor.

Summary of the invention

The problem to be solved in the present invention is to provide a kind of seal gum.This seal gum, weather resistance is good, can adapt to the acute variation of envrionment temperature between h and c, good sealing effect.

For solving the problem, take following technical scheme:

The feature of seal gum of the present invention is made up of the raw material of following parts by weight:

Toluene 24 ~ 26 parts;

23 ~ 25 parts, petroleum pitch;

Dibutyl phthalate 0.9 ~ 1.1 part;

0.5 ~ 0.7 part, zinc oxide;

Chloroprene rubber 48 ~ 52 parts;

Stearic acid 0.4 ~ 0.6 part;

Tetramethyl-thiuram disulfide 0.05 ~ 0.07 part;

1.9 ~ 2.1 parts, magnesium oxide;

First petroleum pitch heating is dissolved and be in a liquid state, and slough moisture, removing impurity;

While stirring, add the toluene of 50 % by weight, mix, obtained bituminous solution;

Then, chloroprene rubber, dibutyl phthalate, zinc oxide, chloroprene rubber, stearic acid tetramethyl-thiuram disulfide are dropped into together with magnesium oxide and rubber mixing machine carries out mixing, obtain micelle;

Afterwards, described micelle is pressed into the thin slice of 1 ~ 2 mm thick;

Afterwards, described thin slice is cut into small shreds;

Afterwards, described small shreds is dropped in stirrer together with the toluene of remaining 50 % by weight, stirs 3 ~ 5 hours, obtain chloroprene rubber solution;

Finally, bituminous solution and chloroprene rubber solution are put together, stirs, obtained seal gum.

Take such scheme, have the following advantages:

Because seal gum of the present invention is made up of toluene, petroleum pitch, dibutyl phthalate, zinc oxide, chloroprene rubber, stearic acid, tetramethyl-thiuram disulfide and magnesium oxide, weather resistance is better, the acute variation of the envrionment temperature between h and c can be adapted to, good sealing effect.
