Description
Technical field
The present invention relates to paint field, particularly, relate to waterborne edge sealing paint, and its preparation method.
Background technology
Along with the develop rapidly of wood furniture industry, solid wood is become a useful person, and supply falls short of demand, derived the environment-friendly materials such as density board, ecosystem plate of the compacting such as the raw material that utilizes sawdust, stalk, branch.Such material plane does not have problems when using, but when being divided into the sheet material of different size, four limits can very unfairness, smooth, has very large gap, when with the construction technology identical with spraying plane, is difficult to fill smooth simultaneously.In order to solve this problem, edge sealing paint arises at the historic moment.
What edge sealing paint was mainly used in the side of density board material and tangent plane fills and leads up the process such as edge sealing, such as, for real look edge sealing of furniture, American Style Furniture edge sealing, plate fitment edge sealing etc.Can replace traditional scraping the primer painting process such as ash, seal coat; Also can be used for the bottom applications such as the toy of special industry, artwork, ornaments; Also can be used for high performance real color bottom paint, make priming paint, floating coating uses, greatly save painting cost.
Edge sealing paint kind conventional at present has PU edge sealing paint, NC edge sealing paint or waterborne edge sealing paint.The above two are because containing a large amount of organic solvent, not environmentally, dangerous, and are harmful to workmen's health, gradually replace by waterborne edge sealing paint.Number of patent application is CN 201010131150.8 " waterborne edge sealing paint and complete processing thereof " is that CN 201110175391.7 " super-high solid content quick-drying edge sealing paint and production method thereof based on aqueous polyurethane " belongs to water-based system, the low evil of low toxicity with the patent No..Above-mentioned two patents are all adopt waterborne polyurethane resin as main body filmogen, adopt conventional powder as filler, fillibility, rate of drying and hardness still can be improved.
