Abstract
The invention provides an emulsion paraffin water-proofing agent for a particleboard. The emulsion paraffin water-proofing agent is prepared from solid paraffin, stearic acid and water as main raw materials, peregal-O and polysorbate as emulsifiers, sodium tripolyphosphate as a catalyst, and sodium carboxymethylcellulose as a cross-linking agent through step-by-step emulsification and saponification. The water-proofing agent has the advantages of high solid content, uniform film-forming property, small granularity, significant dispersity and waterproofing effect, simplicity in preparation process, easiness in production and operation, and low demands on equipment and process condition, can be produced by an artificial board glue manufacturing workshop without adding equipment, and is high in quality and low in price.
Description
Technical field
The present invention relates to the water-resisting agent that hydrophilic and oleophilic Wood-based Panel Production uses, especially a kind of emulsion paraffin water repellent and manufacture method being applied to shaving board production and application.
Background technology
In shaving board production process, in order to increase the water resistance of shaving board, usually apply water-resisting agent.In recent years, China's shaving board production development speed is swift and violent, cause the petrochemical complex raw and auxiliary material of shaving board production in short supply, the main water-resisting agent that paraffin is produced as shaving board is widely used, but along with the industrial chemicals such as paraffin appear in oil price constantly soaring, supply falls short of demand, market value Continued.Many manufacturers and scientific research institution replace paraffin at other water-resisting agents of research searching at present.Emulsion paraffin water repellent is carrier with paraffin, is equipped with emulsifying agent, and the reaction such as stablizer forms, and product stability is good, is considered to the substitute of paraffin.Emulsified olefin, in shaving board manufacturing processed, by breakdown of emulsion effectively, can make small Wax particles separate out from aqueous phase, be adsorbed on equably on wood particle particle, thus improve the quality of shaving board, reduce paraffin consumption, thus extensively produced by shaving board.
Emulsified olefin used for shaving board is usual and urea-formaldehyde resin adhesive mixing and stirring is after-applied, because urea-formaldehyde resin or modified urea-formaldehyde resin are hydrophilic glues, and paraffin itself is that oleophylic solid matter is water insoluble, can not by the saponification of alkali institute, therefore how Emulsification of Paraffin being become fine particle, dispersed and have hydrophilic and oleophilic function, is that tackling key problem solves one of key of water-resisting agent used for shaving board.In addition, how shaving board Market competition, and the situation such as current ubiquity physical strength and waterproof effect difference, improve the even water-fast waterproof quality of board quality, thus widen shaving board Application Areas, become the problem that shaving board enterprise urgently solves.
Summary of the invention
For the above-mentioned bottleneck problem of emulsified olefin used for shaving board, the object of this invention is to provide a kind of emulsion paraffin water repellent formula used for shaving board and concrete preparation method, this water-resisting agent has emulsification, dispersion and good water-proof effect, the advantages such as particle is little, arbitrary proportion and urea-formaldehyde resin can obtain modified urea-formaldehyde resin and mix and apply, be widely used in shaving board to produce, meet that the consumption wax amount of shaving board to water-resisting agent is low, good waterproof performance and produce simple composite request.
