Wood anti-mildew agent is applicable to all kinds of products made of logs, solid wood, plywood, fiberboard, composite boards, etc. It is widely used in furniture, building materials, decorative materials, yacht decks, packaging boxes, artwork, stationery and other industries.
Wood anti-mildew agent can avoid the problems of corrosion, decay, discoloration and insects caused by mold, bacteria, moths and algae, etc. It can maintain the physical and mechanical properties of wood products as it inhibits or stops the growth of odor-causing bacteria and molds. Extends the service life of wood products, keeps them hygienically clean and prevents odor generation. AEM5700-1 anti-mildew and anti-bacterial agent is a green anti-mildew agent, which does not contain substances harmful to human body and bad environment.
Reaction with epoxy resin
The isopropoxy group in titanate can react with epoxy resin. It can either undergo alcoholysis reaction with the hydroxyl group in epoxy resin or directly react with epoxy group. Reaction formula:
RCH-CH, +G-CHrO), Ti—-RCH-CHy OTi(O-CHy)
The isopropoxy group attached to the titanium atom in the above product can continue to react. Therefore, titanium tetraisopropoxide or a titanium chelate containing two or more isopropoxy groups can be used as a room temperature crosslinking agent for epoxy resins.
Combining the above-mentioned various reactions, the isopropoxy group in titanate can react with substances containing hydroxyl groups or protons, including reactions with hydroxyl groups or protons on the surface of pigments and fillers. These reactions are all reversible reactions. Because the reaction product is isopropanol, it has a low boiling point (82.5°C) and is easy to volatilize. As long as it is heated slightly, the reaction can proceed to the end and become an irreversible reaction.
The mechanism of action of 6 functional regions in the molecular structure of titanate
The molecular structure of titanate coupling agent can be divided into 6 functional areas, paraffin wax emulsion uses each of which has its own characteristics and plays its own role in the coupling mechanism.
