Research Progress of Mini-Emulsion in the Wood Industry

Abstract:

This paper reviews the mini emulsion in the timber industry and development. Introduction of the small foreign Emulsion Synthesis and Application of the latest developments. Mini emulsion adhesive is a rapid development over the past decade and has practical use of new adhesives, with no formaldehyde pollution, water resistance and anti-aging performance, the application of mini emulsion polymerization of a wide range of performance. Discusses the mini prospects for the development of emulsion adhesive. With the development and application of wood-based panel industry continues to expand the range of wood products of a higher water resistance and durability requirements, adhesive application market more widely, the variety is also increasing. Between dissimilar materials, composite wood and the growing need for the traditional timber industry with plastic, urea formaldehyde(UF),phenol formaldehyde(PF),melamine formaldehyde(MF)plastic(the Department of formaldehyde glue) can not fully meet, in which The largest amount of formaldehyde, urea-formaldehyde glue pollution problems caused by people even more widespread concern, it is necessary to vigorously develop new wood adhesive for industrial use. Emulsion is a rapid development over the past decade and have been utility of the new adhesive, with no formaldehyde pollution, water resistance and excellent aging resistance, and adaptability to be glued materials, etc., widely used in wood glue and secondary processing Therefore, great attention by the timber industry, competing for exploitation. Diameter of dispersed droplets in the emulsion 50 ~ 500nm, between macro and micro emulsion between emulsion, known as fine emulsion. Miniemulsion system, in the sub-micron particle size, larger than monomer swollen micelles (diameter of about 40 ~ 50nm), less than the monomer droplets (diameter of about 1000nm), a wide size distribution. Miniemulsion polymerization can not be compared with the advantages of conventional[1], Therefore, polymer and materials science has become a hot research field, in the preparation of the special structure of polymers (such as the core - shell particles, polymer nanoparticles, polymer interpenetrating network structure, etc.) and stable polymer dispersions have Very broad application prospects.
