Wacker introduces a kind of redispersible latex powder produced by biological acetic acid

Wacker introduced a kind of redispersible latex powder produced by using biological acetic acid The new redispersible latex powder is especially suitable for the production of waterproof mortar, dry mixed mortar for external wall insulation system and other building materials Sustainable and environmentally friendly buildings play an important role in global efforts to reduce carbon dioxide emissions To this end, architects and building developers are paying more and more attention to the use of renewable raw materials, and more and more building materials manufacturers are also providing corresponding solutions Wagley produced this kind of new redispersible latex powder with biological acetic acid As a by-product of the wood processing industry, bio based acetic acid is produced in the process of producing fiber materials for the paper industry The wood used is from the woods within 400 km around the production base of wakeboghausen and certified by PEFC (forest certification system accreditation program) Bio based acetic acid has the advantages of high purity, low water content and good quality It can completely replace the acetic acid based on natural gas or oil production Wacker uses vinyl acetate monomer and vinyl acetate monomer to produce vinyl acetate ethylene (VAE) copolymer emulsion The liquid polymer emulsion used for coating production is also produced Then Wacker uses a large spray dryer to process the emulsion into redispersible latex powder The liquid polymer emulsion can be instantly dried into fine powder after it is sent to the hot airflow by the nebulizer This kind of adhesive can give dry mixed mortar, tile adhesive, waterproof mortar and other building materials high flexibility and adhesion Biological acetic acid can be mixed with conventional acetic acid in the production process and directly enter the existing production line of Wacker There is not a fraction of difference between the quality and properties of the VAE binder, whether the conventional acetic acid or bio acetic acid is used, and its chemical and physical properties are the same The new redispersible latex powder has no rheological property The improved material has more excellent adhesion, flexural strength, molding, scrub resistance and construction performance, but the fluidity, thixotropy or water retention of the material will not be greatly affected This new type of binder is especially suitable for the preparation of low emission mortar with strong flexibility and good adhesion, which is far superior to polystyrene organic substrate used in exterior wall insulation system.
