Description
Technical Field
The invention relates to an adhesive used for a waterproof coiled material, in particular to a single-component polyethylene polypropylene fiber waterproof coiled material adhesive.
Background
The polyethylene polypropylene fiber waterproof coiled material is a waterproof material widely applied, and the market quantity is in the first place in the high polymer waterproof coiled material. The polyethylene polypropylene fiber waterproof coiled material needs to be matched with an adhesive to form composite waterproof during construction, so that the matched adhesive has definite requirements, not only needs to have good bonding performance and waterproof sealing performance, but also needs to have certain flexibility, and the requirements are met in CECS 199 which is mainly compiled by the China Association for engineering construction standardization: 2006 "technical code for composite waterproof engineering of polyethylene polypropylene coiled material" has clear regulations. In addition, when the joints and special parts of the coiled material (such as the coiled material and materials of iron, aluminum, PVC, and the like) are bonded, the adhesive is required to be firmly bonded so as to achieve the waterproof sealing effect. At present, the polymer modified cement bonding material used by the polyethylene polypropylene waterproof coiled material has good bonding performance with a base layer (cement base), but the waterproof sealing performance and the flexibility are poor, so that the composite waterproof requirement of the composite waterproof engineering technical specification cannot be met, and the problems of bonding and sealing of seams and special parts cannot be solved. In order to improve the flexibility and the waterproof sealing performance of the adhesive, when the content of the polymer in the adhesive is increased, namely the polymer cement ratio is increased, the adhesive cannot be solidified when the common portland cement is adopted.
In order to solve the problems, a previous patent application with an authorization publication number of CN108892458B of the applicant discloses a polyethylene polypropylene waterproof coiled material adhesive, wherein the polyethylene polypropylene waterproof coiled material adhesive uses sulphoaluminate cement to replace common silicate cement, and a plurality of auxiliary agents are added, so that the adhesive can still be cured when the poly-cement ratio is increased, and the adhesive is used for waterproof construction of a polyethylene polypropylene waterproof coiled material, and achieves the purposes of sealing, preventing water and improving flexibility. However, the polyethylene polypropylene waterproof coiled material adhesive is a bi-component product, namely the product consists of two parts, namely liquid material and powder material, and has certain defects compared with a single-component product, namely the two parts, namely the liquid material and the powder material, are required to be produced, packaged, stored and transported respectively, and meanwhile, the problems of corrosion prevention and freezing prevention of the liquid material storage and transportation need to be considered.
The 'Chinese building waterproof' journal (3.16.2007) is published with a 'research on a single-component water-resistant polyethylene polypropylene composite waterproof coiled material bonding material', the bonding material in the text consists of ordinary portland cement, quartz sand, dry milk, HPMC (hydroxy propyl methyl cellulose) and other additives, the performance of the product is better than that of the bonding material prepared by using 107 cement as a bonding material, but the product does not meet the requirements of 'polyethylene polypropylene coiled material composite waterproof engineering technical specification', the bonding peel strength of the coiled material and the coiled material also does not meet the requirements of JC/T863-2011 'macromolecule waterproof coiled material adhesive' standard which is more than or equal to 1.5N/mm, the bonding peel strength of other materials is lower at special positions, and in short, the bonding material does not meet the requirements of the current relevant standards.
