Problems solved by technology

[0004] 2. From the existing adhesive products and raw material formulas, it can be seen that in order to reduce the raw material cost of the products or because the technology cannot meet the requirements, the manufacturers do not add any flame retardant ingredients to almost all products, and there are no labels on the market. There are "flame retardant" adhesives
[0005] 3. The waterproof performance of the adhesive itself is low
Many existing water-emulsion adhesives only have general water resistance and cannot achieve true waterproof function. After encountering water or soaking in water for a period of time, the adhesive film will soften and the bonding parts will come off.
[0006] 4. Poor aging resistance
Otherwise, the adhesive will become discolored and brittle in a short period of time, greatly shortening the service life of the adhesive and the product to be adhered

Embodiment 1

[0021] A pressure-sensitive SEBS rubber adhesive, its components and mass ratio are: SEBS: 20%; SBR: 30%; SBS: 5%; SIS: 3%; nano calcium carbonate: 5%; : 10%; paraffin oil: 27%.

Embodiment 2

[0022] Embodiment 2: a kind of preparation technology of pressure-sensitive type SEBS rubber adhesive, the steps are as follows:

[0023] 1), according to the mass ratio to select the appropriate measurement of raw materials, the raw materials are as follows: SEBS, SBR, SBS, SIS, nano-calcium carbonate, rosin glycerin, paraffin oil;

[0024] 2), adding the above-mentioned raw materials into the batching mixing tank, heating and fully stirring, in this step, the heating temperature is 80-120°C;

[0025] 3) After the raw materials in the mixing tank come out, they enter the colloid mill to ensure that the raw materials are pure, hygienic and pollution-free;

[0026] 4), the raw material that step 3) comes out enters in the cooling mixing tank, makes binder;

[0027] 5), the binding agent that comes out in step 4) carries out inspection test, packs storage, obtains the pressure-sensitive type SEBS rubber binding agent that meets the standard.

[0028] The SEBS in the invention ...

Abstract

The invention discloses a pressure-sensitive SEBS (Styrene-butadiene-styrene Block Copolymer) rubber binder and a preparation process thereof. The pressure-sensitive SEBS rubber binder comprises the following components by mass percent: 10 to 25% of SEBS, 20 to 40% of SBR (Styrene Butadiene Rubber), 3 to 9% of SBS (Styrene Butadiene Styrene), 2 to 4% of Styrene Isoprene Styrene, 4 to 8% of nano calcium carbonate, 6 to 16% of rosin glycerol, and 20 to 35% of paroline. The pressure-sensitive SEBS rubber binder is outstanding in ageing resistance, high in plasticity and high in elasticity, can quickly bind, shows remarkable flame retardant performance and aging resistance, and is also high in shockproof performance and heat preserving performance, relatively high in elasticity, waterproof and airproof.

Description

technical field [0001] The invention belongs to the field of adhesives, in particular to a pressure-sensitive SEBS rubber adhesive. Background technique [0002] At present, there are many varieties in the field of adhesive materials, especially more adhesives for waterproof materials. These adhesives all have many common shortcomings, namely: [0003] 1. Since the raw materials are organic resin, rubber, solvent and additives, it is a very good flammable material, which will burn immediately when exposed to fire, and it is very easy to cause a fire. [0004] 2. From the existing adhesive products and raw material formulas, it can be seen that in order to reduce the raw material cost of the products or because the technology cannot meet the requirements, the manufacturers do not add any flame retardant ingredients to almost all products, and there are no labels on the market. There are "flame retardant" adhesives. [0005] 3. The waterproof performance of the adhesive its...
