Special SBR styrene butadiene rubber asphalt modifier for waterproofing
New product introduction
In order to pushing the industry development, improving product quality, meeting with the demand of customers. HaiFang Rubber Technology developed XYF - ( item no. 095) styrene-butadiene rubber modifier in 2019.
It grafted based on the latex and in particles form. In order to guarantee the high content at the same time, compared with normal SBR products, it can be dissolved without using colloid mill and the dissolution time is shorter. As a new kind of environmental protection material. Its main advantages: Lower melting temperature, reducing production cost, greatly reducing the dust while feeding compared with normal SBR powder.
Product features
095 Waterproof SBR styrene butadiene rubber asphalt modifier is made by a certain amount of styrene in SBR styrene butadiene latex, initiated and catalyzed reaction, the formation of SBR rubber latex with a certain degree of interposition thermoplastic. The experimental results show that the high temperature properties, tensile properties, tensile strength, bonding strength and anti-aging properties of the materials can be improved obviously by adding it.
To meet different customers requirements, 095 modifier was upgraded to two different kinds of products: High and low-temperature property.
High temperature performance: Cohesion strength is higher than that of ordinary SBR modifier with strong peeling strength, the softening point is 4-6 higher than ordinary SBR modifier. Recommended for using in non- curing products.
Low temperature performance: It is better than the ordinary SBR modifier, low temperature index is 4 lower than the normal SBR modifier, and it has a better viscosity. Recommended using in type adhesive material.

Method of use
A certain proportion of styrene butadiene rubber powder should be mixed slowly into the emulsified bitumen at 140 C-150 C. Then raising the temperature to 185 C-195 C for stirring, until the styrene butadiene rubber powder is fully mixed evenly and swollen while stirring about one and a half hour and with no distinct particles.
Various ionic forms of styrene butadiene latex emulsifying asphalt modifier
Application field
Various ionic forms of styrene butadiene latex emulsifying asphalt modifier are mainly used in the adhesive layer of road engineering, sealing layer, modified dilute slurry sealing layer and micro-surface, bridge deck waterproof bonding layer, waterproof coating of building waterproof engineering, waterproof ointment and other aspects.
Product features
Various ionic forms of butadiene latex emulsifying asphalt modifier, is a stable emulsion synthesized by high polymer material under the condition of low temperature, it is developed according to the properties of modified emulsified asphalt. The temperature sensitivity of asphalt can be significantly improved by emulsion asphalt modified with butadiene latex, low temperature property, adhesion property, crack resistance and aging resistance can be improved.
Waterproof rubber spraying quick-setting latex can significantly improve the spraying quick-setting rubber asphalt waterproof coating after curing of heat resistance, bonding strength, low temperature flexibility, tensile properties and the puncture resistance after the coating film, It amends the coating after curing, such as its resistance to puncture and poor elastic recovery.
Various grades of powder styrene butadiene rubber asphalt modifier
Application fields
Various grades of styrene butadiene rubber powder asphalt modifiers are mainly used as building waterproof material. Such as self-adhesive rolling, non-curing waterproof coating, reactive self-adhesive rolling. Some of the high content powder styrene butadiene rubber asphalt modifiers can also be used in the modification of road asphalt.
Product features
Styrene-butadiene rubber powder asphalt modifier, which is polymerized by styrene and butadiene at low temperature (5) and it is born by the characteristics of waterproof rolling material and non-curing waterproof coating.
When mixed the bituminous waterproofing roll with XY-5 styrene butadiene rubber powder, because of the active functional groups of powdered styrene butadiene rubber itself, it makes waterproof material to produce a special activity, making the material in the solidification process of Portland cement, with silicate cement of chemical compounds, producing chemical combination, forming a strong cohesive force and improving the waterproof materials and cement bond. At the same time, powdered styrene butadiene rubber can also greatly improve the performance of low temperature and tensile properties of the waterproof materials.
