Abstract

The invention discloses a high viscosity non-asphalt base self-adhesive glue for waterproof coiled materials. The high viscosity non-asphalt base self-adhesive glue is prepared from the following raw materials by mass: 27-32% of a compatibilizer, 4-6% of SBS, 0.5-3% of PP, 3-8% of TPR, 0-9% of SBR, 0-3% of EVA, 3-13% of a tackifier, and 31-48.5% of filler. The self-adhesive glue is completely prepared from a high molecular polymer base material and does not contain any asphalt component. Experiments show that the high viscosity non-asphalt base self-adhesive glue for waterproof coiled materials provided by the invention can meet existing waterproof construction requirements and also can improve the use durability, and pigments of different colors can be added to prepare glues with various colors to achieve personalized customization, thereby realizing differentiation from modified asphalt self-adhesive glue.

Description

Waterproof roll high viscosity non-bituminous base self-adhesive and preparation method thereof

Technical field

The invention belongs to building waterproof coil manufacturing technology field, more particularly, to a kind of waterproof roll is non-with high viscosity Asphaltic base self-adhesive and preparation method thereof.

Background technology

At present, the self-adhesive used by the waterproof roll of market upper band self-adhesive layer is made with polymer modified asphalt base mostly, Its matrix pitch is modified through high molecular polymer, and performance can substantially meet construction and waterproof requirement.But, from useful life longevity From the point of view of, general asphaltic base waterproof roll but far can not meet with building the requirement with the life-span, particularly subway tunnel etc. The infrastructure of key project, requires higher, it is it is difficult to ensure that its ne-leakage phenomenon in the range of design period to classification of waterproof. Therefore, develop a kind of energy and can meet the waterproof roll self-adhesive that existing waterproof construction requirement can improve durability again, just become For a very urgent and significant research topic.

Content of the invention

The technical problem to be solved in the present invention is to provide a kind of water proofing property and all good waterproof roll high viscosity of durability Non-bituminous base self-adhesive and preparation method thereof.

For solving above-mentioned technical problem, the present invention employs the following technical solutions：Waterproof roll high viscosity non-bituminous base is certainly Viscose glue, is made up of the raw material of following mass percent：Compatilizer 27-32%, SBS 4-6%, PP 0.5-3%, TPR 3-8%, SBR 0-9%, EVA 0-3%, tackifier 3-13%, inserts 31-48.5%.

The mass percent of compatilizer is 29-32%, and the mass percent of SBS is 4-5.5%, the mass percent of TPR For 5-8%, the mass percent of SBR is 2-9%, and the mass percent of EVA is 0-3%, and the mass percent of tackifier is 7- 9%.

Above-mentioned waterproof roll high viscosity non-bituminous base self-adhesive, also includes the pigment of mass percent 5%.

Compatilizer is softening oil, and SBS is star-like styrene analog thermoplastic elastomer, and PP is polypropylene, and TPR is SBS base material Modified thermoplastic elastomer (TPE), SBR is powder styrene butadiene rubber, and EVA is graininess ethylene-vinyl acetate copolymer, and tackifier are C9 Petropols, pigment is paint pigment, and inserts is stone flour.

Inserts particle diameter≤100 μm.

The above-mentioned waterproof roll preparation method of high viscosity non-bituminous base self-adhesive, operation according to the following steps is carried out：

<1>Compatilizer is added and after reactor, is heated to 130 DEG C；

<2>Tackifier are put into step<1>Reactor in, be blended 30min, control temperature be less than 130 DEG C；

<3>SBS, PP, TPR, SBR and EVA are put into step<2>Reactor in, be blended 1-1.5h, control temperature do not surpass Cross 185 DEG C；

<4>Inserts is put into step<3>Reactor in, be blended 1-1.5h, control temperature be less than 165 DEG C, obtain final product Waterproof roll high viscosity non-bituminous base self-adhesive.

Step<4>The waterproof roll of gained, with adding pigment in high viscosity non-bituminous base self-adhesive, is mixed thoroughly.

There is poor durability for existing waterproof roll asphaltic base self-adhesive, inventor have developed a kind of waterproof Coiled material high viscosity non-bituminous base self-adhesive, is made up of the raw material of following mass percent：Compatilizer 27-32%, SBS 4- 6%, PP 0.5-3%, TPR 3-8%, SBR 0-9%, EVA 0-3%, tackifier 3-13%, inserts 31-48.5%.Should Self-adhesive is made using high molecular polymer base-material completely, without any asphalt component.Experiment shows, waterproof roll of the present invention is used High viscosity non-bituminous base self-adhesive can meet existing waterproof construction requirement and can improve useful life longevity again, and can rely on and add Plus the pigment of different colours prepare shades of colour carry out personalization customization, with traditional modified pitch self-adhesive (pitch true qualities, I.e. black) make a distinction.

Specific embodiment

For being further elucidated with the present invention, below citing describes in detail.

The waterproof roll preparation of high viscosity non-bituminous base self-adhesive

Formula (mass percent)：Compatilizer 27-32%, SBS 4-6%, PP 0.5-3%, TPR 3-8%, SBR 0- 9%, EVA 0-3%, tackifier 3-13%, inserts 31-48.5%, pigment 5%.Wherein, compatilizer is softening oil (Guangdong ten thousand Deep petrochemical industry Co., Ltd), SBS is star-like styrene analog thermoplastic elastomer, and PP is polypropylene, and TPR is thermoplastic elastomer (TPE), SBR is powder styrene butadiene rubber, and EVA is graininess ethylene-vinyl acetate copolymer, and tackifier are C9 Petropols, and pigment is to apply Material pigment, inserts is stone flour (particle diameter≤100 μm).

Preparation method is as follows：

<1>Compatilizer is added and after reactor, is heated to 130 DEG C；

<4>Inserts is put into step<3>Reactor in, be blended 1-1.5h, control temperature be less than 165 DEG C, obtain final product Waterproof roll high viscosity non-bituminous base self-adhesive, is added as needed on being suitable for coloured pigment, mixes thoroughly；
