PVC building waterproof joint material is mainly made of coal tar、 modified with PVC、 and mixed with stabilizers、 plasticizers、 fillers、 etc. After thermoplastic、 a polymer structure is formed. PVC plays a cross-linking role in forming polymers、 providing strength and heat resistance to the polymer. It has the general characteristics of polymer compounds、 which soften when heated、 harden when cooled、 and exhibit an amorphous elastoplastic shape at room temperature. PVC building waterproof joint materials can be divided into two types in terms of appearance on the market. One type is woven bag packaging、 commonly known as plastic ointment、 which is in the form of solid amorphous elastic plastic and is referred to as shaped joint materials in the standard. The raw material is waste PVC plastic to modify coal tar. It needs to be melted into a flowing state on site before construction; Another type is barrel packaging、 commonly known as polyvinyl chloride adhesive、 which uses polyvinyl chloride resin to modify coal tar in the raw material、 forming a paste like semi fluid、 and is referred to as J-shaped joint material in the standard. It needs to be thermoplastic on site before construction can be carried out
