APP glue 4-9 part.
Described pitch is the mixture of No. 10 pitches and No. 60 pitches, No. 10 pitch 9-21 parts wherein, No. 60 pitch 23-33 parts.
Can also contain inorganic reinforcer or organic reinforcing agent in the described immersion oil coating layer.
Described overlay film layer can be aluminium foil, plastic sheeting, barrier paper or fine sand.
The preparation technology of this atactic polypropylene (APP) modified bituminous waterproof sheet material is characterized in that step is as follows:
Step 1 adds pitch in stirred vessel, carry out 2 hours thermal dehydrations under 185 ℃ of-190 ℃ of temperature;
Step 2 adds residual oil and stirred 1 hour in stirred vessel;
Step 3 adds APP glue and stirred 1 hour in stirred vessel;
Step 4 is reduced to 165 ℃ with temperature in the stirred vessel;
Step 5 adds EPDM rubber powder, butyl rubber powder, French chalk and stirs in stirred vessel, the material of the immersion oil coating layer made is flowed into immersion cell;
Step 6 is launched mylar to put into immersion cell, carries out the immersion oil coating;
Step 7, the thickness of control immersion oil coating layer, cooling;
Step 8, overlay film curls, packs, puts in storage.
In the described step 5, in the material of immersion oil coating layer, add reinforcing agent and stir.
Described EPDM rubber powder has another name called second third glue, English name: Ethylene propylene Rubber, behind ethene and copolymerization of propylene, importing on the EP main chain has the 3rd composition of two strands to form on a small quantity.
Described APP glue claims random polypropylene again.
Residual oil: English name residual oil is with the residual oil of crude oil through the decompression distillation gained.
Beneficial effect of the present invention is as follows:
1, the present invention is behind the composition that has increased rubber, and hardness, elasticity all increase,
2, unparalleled key on the ethylene propylene diene rubber molecular structure main chain that is adopted is saturated, so structure is more stable, product is difficult for rupturing.
3, high and low temperature resistance is good, can spend under 140 degree-25 and use, and the UV resistant irradiation is more outstanding.
4, the increase of rubber constituent improved that product is acidproof, alkaline-resisting, salt tolerant, corrosion resistant performance.
5, product appearance light, smooth surface, attractive in appearance.
6, reduced the consumption of SBS in the prescription, can make compound per ton reduce by 1000 yuan.
