Preparation method of elastomer modified asphalt waterproof roll capable of being placed in wet

Abstract

The present invention discloses a preparation method of elastomer modified asphalt waterproof roll capable of being placed in wet, comprising the following steps: uncoiling a carcass reinforcement layer, storing the carcass reinforcement layer on a store frame, buffering, pre-impregnating the carcass reinforcement layer by high-grade petroleum asphalt and squeezing to dry for complete impregnation, coating an elastomer modified asphalt glue stock on the upper and the lower surfaces of the carcass reinforcement layer, cooling the elastomer modified asphalt glue stock by water and performing air drying, coating a self-adhesive glue stock respectively on the surface of the elastomer modified asphalt glue stock layer, covering a conglutination resistant isolation layer respectively on the surface of the self-adhesive glue stock layer, cooling the product after the processes above by a flow-through cooling roll, storing the product on a store frame, buffering and finally coiling the product. The roll of the invention has low preparation cost, good stability of structure and thermal expansivity, security construction, environmental protection and reliable adhesion. The adhesion between the self-adhesive glue stock and the elastomer modified asphalt glue stock is strong and the roll prepared has reliable waterproof effect.

Description

technical field [0001] The invention relates to a production method of building materials, more specifically, a production method of an elastomer (SBS) modified asphalt waterproof coiled material that can adopt a wet laying method. Background technique [0002] At present, the self-adhesive SBS membranes that have been applied are single-sided or double-sided self-adhesive for dry-laying construction. The cold construction method is mainly used to solve the waterproofing projects where open flame hot-melt SBS membranes cannot be used in some waterproof parts such as chemical plants. The self-adhesive adhesive of traditional self-adhesive SBS coils is coated on the surface material of ordinary SBS coils regardless of single-sided or double-sided self-adhesive. Taking the traditional self-adhesive SBS coils with double-sided self-adhesive as an example, its The product structure from top to bottom is release paper or film, ordinary self-adhesive layer, PE film layer (that is, ...

Problems solved by technology

[0002] At present, the self-adhesive SBS membranes that have been applied are single-sided or double-sided self-adhesive for dry-laying construction. The cold construction method is mainly used to solve the waterproofing projects where open flame hot-melt SBS membranes cannot be used in some waterproof parts such as chemical plants.

The self-adhesive adhesive of traditional self-adhesive SBS coils is coated on the surface material of ordinary SBS coils regardless of single-sided or double-sided self-adhesive. Taking the traditional self-adhesive SBS coils with double-sided self-adhesive as an example, its The product structure from top to bottom is release paper or film, ordinary self-adhesive layer, PE film layer (that is, the surface material of ordinary SBS coil), SBS modified asphalt layer, carcass reinforcement layer, SBS modified asphalt Layer, PE film layer (that is, the bottom material of ordinary SBS coils), ordinary self-adhesive layer, release paper or film; its production and molding process is: carcass prepreg - coated with SBS modified asphalt layer - coated with bottom layer PE film—covering layer PE film—common self-adhesive layer on the surface layer—common self-adhesive layer on the bottom layer—cooling—storage of finished products—rewinding of finished products, due to the modification of ordinary self-adhesive layer and SBS There is a PE film layer between the asphalt layers. With the rapid aging of the PE film after construction, the ordinary self-adhesive layer and the SBS modified asphalt layer will be peeled off, resulting in failure of the waterproof layer.
