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

A kind of pressure sensitive SEBS rubber cement and preparation technology thereof

Technical field

The invention belongs to binding agent field, specifically, relate to a kind of pressure sensitive SEBS rubber cement.

Background technology

At present, the kind in adhesive material field is a lot, more in particular for the tackiness agent of water-proof material aspect.All there are many common shortcomings in these tackiness agent, that is:

1, because starting material are all organic resin, rubber, solvent and auxiliary agent, be good inflammable material, meet fire and fire, utmost point fire hazardous.

2, can see from existing adhesive products and composition of raw materials, manufacturer is in order to reduce the material cost of product or not reach requirement because of technology, in nearly all product, without adding any fire retardant composition, on market, also can't see the tackiness agent that indicates " flame retardant type ".

3, the water resistance of tackiness agent itself is low.Existing many water-latex type tackiness agent only have general water tolerance, do not reach real water-proof function, meet water or after soaked for some time, just there will be glued membrane softening, the phenomenon that bonding piece is thrown off.

4, loss of properties on aging.In order to make organic materials there is good ageing-resistant performance, just must in raw material, add a certain amount of aging dose.Otherwise binding agent just there will be electrochromic variable crisp in a short period of time, the work-ing life that greatly shortens tackiness agent and glued product.

For this reason, researching and developing a kind of tackiness agent with good flame-retardance energy and ageing resistance is of great significance the adhesive material field tool of China.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides a kind of pressure sensitive SEBS rubber cement of realizing quick-binding, thering is good anti-flaming function and ageing resistance.

For addressing the above problem, the technical solution adopted in the present invention is:

Pressure sensitive SEBS rubber cement, is characterized in that: its component and quality proportioning thereof are: SEBS:10-25%; SBR:20-40%; SBS:3-9%; SIS:2-4%; Nano-calcium carbonate: 4-8%; Rosin glycerine: 6-16%; Paraffin oil: 20-35%.

As the improved technical scheme of one, its component and quality proportioning thereof are: SEBS:20%; SBR:30%; SBS:5%; SIS:3%; Nano-calcium carbonate: 5%; Rosin glycerine: 10%; Paraffin oil: 27%.

The present invention also provides a kind of pressure sensitive SEBS rubber cement preparation technology, and step is as follows:

1), choose the raw material of suitable metering according to quality proportioning, raw material is as follows: SEBS, SBR, SBS, SIS, nano-calcium carbonate, rosin glycerine, paraffin oil;

2), above-mentioned raw materials is joined in batching stirred pot to the stirring of heating;

3), the raw material in stirred pot out enters into afterwards colloidal mill and grinds;

4), step 3) raw material out enters into stirred pot and stirs cooling;

5), step 4) in the chemical examination of testing of binding agent out, packaging warehouse-in.

Owing to having adopted technique scheme, compared with prior art, in the present invention, SEBS has excellent ageing-resistant performance, has both had plasticity-, has again snappiness, can process use without sulfuration.SBR is a kind of synthetic rubber foam, feel exquisiteness, softness, high resilience, have shockproof, insulation, elasticity, waterproof, the feature such as airtight.The characteristics such as SBS is styrene series thermoplastic elastomer, can contact with water, weak acid, alkali etc., has good tensile strength, and skin friction coefficient is large, and low-temperature performance is good, and electrical property is good, good processability.SIS has excellent ripple stopping property and high temperature confining force, the Microphase Separation structures shape that it is unique it in the time being used as tackiness agent, there is unique superiority.

The present invention has excellent ageing-resistant performance, has both had plasticity-, has again snappiness, simultaneously, the pressure sensitive SEBS rubber cement that the present invention makes, realizes quick-binding, has good anti-flaming function and ageing resistance, shockproof, good heat insulating, have elasticity, waterproof, airtight.

Embodiment

Embodiment 1:

A kind of pressure sensitive SEBS rubber cement, its component and quality proportioning thereof are: SEBS:20%; SBR:30%; SBS:5%; SIS:3%; Nano-calcium carbonate: 5%; Rosin glycerine: 10%; Paraffin oil: 27%.

Embodiment 2: a kind of preparation technology of pressure sensitive SEBS rubber cement, step is as follows:

1), choose the raw material of suitable metering according to quality proportioning, raw material is as follows: SEBS, SBR, SBS, SIS, nano-calcium carbonate, rosin glycerine, paraffin oil;
