Abstract

The kiln ash in the waste liquid of this product utilization coke-oven plant, cement mill, the plastic waste of scrap heap, turn waste into wealth, with its coal tar, polychloroethylene blended, thermoplastic, crosslinked, mixing, product has snappiness, and paste performance bending modulus is big, wear-resisting, ultimate compression strength is high, low temperature flexibility is good, and it is poor to have overcome coiled material low temperature flexibility on the market, the incorrigible shortcoming of local defect.

This product also has cold process construction, single ply waterproofing, and the disposable waterproof homework of finishing, save energy is saved characteristics such as man-hour.

Description

Method for producing water-proof material

The present invention belongs to utilize active low-calcium silicate mineral (kiln hood ash) promptly to do compound to do promotor again and be equipped with other inorganic salt modification, make the waterproof roll that contains mineral substance of snappiness, body of paste, single ply waterproofing, cold process construction.

The new type waterproof coiled material of domestic production at present is main material with petroleum pitch mostly, and elasticity is low, more difficult to the convex-concave position, and on-the-spot blowtorch baking is wanted in construction, and is complicated.

The objective of the invention is at the problems referred to above, the development snappiness, to local defect more easily correct, low-temperature flexibility is good, construction is simple, the water-proof material of the cold process construction of easy to maintenance, disposable completion.

The present invention with coal tar, coal-tar pitch, polyvinyl chloride, chlorinatedpolyethylene, waste PVC plastics, listen dioctyl phthalate, dioctyl sebacate, chlorinated paraffin, calcium stearate, cement flue Dust, plumbic acetate, gypsum, flyash, coal benzene oil, phenylethyl naphthylamines

Be raw material production waterproof roll and caking agent, measure coal tar by weight percentage, waste or used plastics 1～50% carries out blend, for taking off HCl, the control polyvinyl chloride produces self-catalysis, add the kiln hood ash, it promptly can be worked as alkaline agent and do promotor and can work as aggregate again and exist and to do compound, add chlorosulphonation with crosslinked raising low temperature flexibilities such as linking agent plumbous oxide, product compactness and thermal stability, listen dioctyl phthalate, dioctyl sebacate for improving the processing characteristics adding, for increasing degree of mobilization, coal benzene oil, more than all kinds of material proportion respectively 1～50%.

Working method

1, takes by weighing coal tar, the coal-tar pitch of specified amount, be heated to 100 ℃ and dewater till do not have a steam bubble, be cooled to 50 ℃ then.

2, take by weighing kiln ash, gypsum, polyvinyl chloride, chlorinatedpolyethylene, calcium stearate, phenyl ethylnaphthalene amine, waste or used plastics, the flyash of specified amount, add the middle blend of working method (1) 20 minutes.

3, take by weighing specified amount listen dioctyl phthalate, dioctyl sebacate, chlorinated paraffin, coal benzene oil adds in the working method (2), add chlorosulphonation, plumbic acetate, phenyl ethylnaphthalene amine when heating up 100 ℃ of plasticizings, carry out crosslinked, after 120 ℃ of sampling quality inspections are qualified, can make waterproof roll by casting.

4, will go up method (3) be cooled to 50 ℃ add thinners sampling quality inspections qualified after, can inject bucket and make caking agent.

Embodiment 1:

Take by weighing coal tar 40 grams, coal-tar pitch 30 grams are by the operation of (1) method.

Take by weighing kiln ash 20 grams, flyash 10 grams, gypsum 0.2 gram, hard calcium acetate 0.5 gram plumbic acetate 1 gram, waste or used plastics 4 grams, polyvinyl chloride 10 grams are by the operation of (2) method.

Take by weighing and listen each 1 gram of dioctyl phthalate, dioctyl sebacate, chlorinated paraffin, coal benzene oil 10 grams, chlorosulphonation 6 grams and operate by (3) method.

Embodiment 2

Take by weighing coal tar 30 grams, coal-tar pitch 100 grams are by the operation of (1) method.

Take by weighing kiln ash 20 grams, flyash 10 grams, gypsum 0.2 gram, calcium stearate 0.3 gram, lime carbonate 0.1 gram, plumbic acetate 0.5 gram, waste PVC plastics 2 grams are by the operation of (2) method.

Take by weighing and listen dioctyl phthalate 2 grams, chlorosulphonation 2 grams are by the operation of (3) method.

Taking by weighing 30 gram coal benzene oil operates by (4) method.

Claims

1, a kind of with coal tar, coal-tar pitch, polyvinyl chloride, waste or used plastics, calcium stearate, chlorinatedpolyethylene, listen dioctyl phthalate, dioctyl sebacate, chlorinated paraffin, cement kiln head ash, plumbic acetate, gypsum, flyash, lime carbonate, coal benzene oil, phenyl ethylnaphthalene amine

, chlorosulphonation is raw material production waterproof roll and tackiness agent, it is characterized in that:

A, above-mentioned starting material coal tar, coal-tar pitch are got 40～60% thermal dehydrations by weight, then with other starting material by 1～25% amount of getting carry out blend mould poly-, crosslinked mixing snappiness, the paste carcass waterproof roll made.

B, coal tar, coal-tar pitch are got 30～50% thermal dehydrations by weight, then other starting material are got the material amount between 1～25%, carry out blend, mould caking agent poly-, crosslinked, mixing, that bonding coiled material is made in dilution.
