Abstract
Disclosed therein is an unvulcanized adhesive waterproof material using reclaimed rubber and a preparation method thereof, and more particularly, an unvulcanized adhesive waterproof material using reclaimed rubber and a preparation method thereof, where reclaimed rubber is added to a softener, a tackifier, a filler, an SBS resin, a PVA pressure sensitive adhesive, etc. and subjected to mechanically forced mixing to form a highly adhesive material, which is then applied on asphalt sheets, HDPE sheets, nonwoven fabric, PE foam, or the like according to the intended use purpose to form a waterproof sheet.
Claims3
An unvulcanized adhesive waterproof material using reclaimed rubber, comprising:
- (a) 18 to 28 parts by weight of reclaimed rubber (EPDM- or NR-based);
- (b) 6 to 15 parts by weight of a softener (paraffin oil or aromatic oil);
- (c) 14 to 24 parts by weight of a tackifier (polybutene- or PVA-based tackifier);
- (d) 40 to 60 parts by weight of a filler (talc, calcium bicarbonate, or cement);
- and
- (e) 2 to 6 parts by weight of an SBS-based thermoplastic resin,
- the ingredients (a) to (e) being mixed together by mechanically forced mixing.
A method for preparing an adhesive waterproof material, comprising:
- adding 18 to 28 parts by weight of reclaimed rubber (EPDM- or NR-based) in a mixer;
- adding 6 to 15 parts by weight of a softener (paraffin oil or aromatic oil) in the mixer;
- adding 14 to 24 parts by weight of a tackifier (polybutene- or PVA-based tackifier) in the mixer;
- adding 40 to 60 parts by weight of a filler (talc, calcium bicarbonate, or cement) in the mixer;
- adding 2 to 6 parts by weight of an SBS-based thermoplastic resin in the mixer;
- and
- mixing the ingredients together by mechanically forced mixing.
