4,4-oxobisbenzenesulfonylhydrazide is abbreviated as OBSH foaming agent. OBSH foaming agent has a large amount of gas, the decomposition product is non-toxic, odorless, and non-coloring. It can be used in plastics and rubber fields, and is known as "universal foaming agent". Montmorillonite (MMT) is a 2:1 layered silicate clay mineral composed of silicon-oxygen tetrahedron and aluminum-oxygen octahedron. Through ion exchange, adsorption, etc., organic molecules can be inserted between the montmorillonite layers, thereby improving the lipophilicity of montmorillonite and its interfacial adhesion in polymers.
A novel organic-inorganic composite foaming agent can be prepared by intercalating OBSH into the montmorillonite layered structure. The OBSH between the montmorillonite layers is limited by the montmorillonite sheets, and then evenly distributed with the distribution and diffusion of the montmorillonite in the matrix material, which can solve the problem of excessive local foaming of pure OBSH, high local decomposition temperature, etc. The low viscosity of the polymer material does not match the foaming temperature. The composite foaming agent obtains both foamed structure and two-dimensional nanostructure, which can endow the foamed material with the advantages of clay nanocomposites.
Product features and uses:
OBSH is a special foaming agent for rubber, which has the characteristics of uniform nucleation and fine and uniform foaming pore size. OBSH foaming agent has stable gas composition and can obtain products with good cell structure. It is the preferred foaming agent for high-quality rubber products. OBSH foaming agent has no induction period for decomposition, fast decomposition speed, gentle degassing without sudden burst, etc. It makes the foaming process easy to control.
Product Features:
1. When this product is used alone, it can produce a fine, high-quality and uniform pore structure, and the foamed products are odorless, tasteless, pollution-free and non-discoloring, especially suitable for odorless and light-colored foamed products.2. Applicable to natural rubber and various synthetic rubbers (such as: EPDM, SBR, CR, FKM, IIR, NBR) and thermoplastic products (such as PVC, PE, PS, ABS), and can also be used in rubber-resin mixtures use.
3. It has good insulation and can be used in the manufacture of wires and cables.
4. Under certain circumstances, it can act as both a foaming agent and a cross-linking agent in the curing mechanism.
Our product foaming agent is generally used to block the gaps of doors and windows, and connect the gaps of doors and windows through its filling function to achieve sealing effect; our products also have color masterbatch foaming agent as the matrix of color masterbatch. Special color masterbatch generally uses the same resin as the product resin as the carrier, and the two have the best compatibility; as well as powder foaming agent, principle and application. Adding some fillers to plastics can improve some properties of plastics. , more suitable for some special purposes; there are also plastic foaming agents, which are used to disperse liquids on the surface of solid particles to form stable foams.
