Abstract
The utility model relates to solidifying promoting agent of adhesive, particularly a micro capsule pill of solidifying promoting agent of phenolic resin. The utility model is composed of a high molecular capsule casing and a capsule core of solidifying promoting agent in the high molecular capsule casing. Therefore, the working life of the solidifying promoting agent and PF resin which are mixed can be extended, and the production efficiency for PF resin bonded plates in the industry for artificial plates is improved.
Description
The utility model relates to a kind of curing catalyst of tackiness agent, especially refers to the curing catalyst microcapsule ball of resol.
At present, water soluble phenol resin (hereinafter to be referred as the PF resin), it is widely used a kind of tackiness agent in the wood-based panel industry, have good weather resistance and bonding strength with this PF resin bonded sheet material, still, PF resin solidification temperature requirement higher (general requirement is higher than 130 ℃), and curing speed is also lower, therefore, pressing cycle is long, causes sheet material agglutinating productivity lower; The someone studies to draw and directly adds curing catalyst in the PF resin, for example: vanay, propylene carbonate, diethyl carbonate etc., produce and promote the solidified effect preferably, but, this class curing catalyst is with after the PF resin contacts, chemical reaction velocity is too fast again, and the PF resin that adds curing catalyst is too short working life, so that can not adapt to the needs of wood-based panel industry rhythm of production.
In view of this, the purpose of this utility model provides a kind of curing catalyst microcapsule ball of resol, utilize polymeric capsule to contain curing catalyst, form the microcapsule ball, in the wood-based plate manufacturing processed, before sheet material and the thermo-compression bonding of PF resin, microcapsule ball and PF mixed with resin are together, do not contact but solidify short agent, stop curing catalyst and PF resin react with the PF resin.
The purpose of this utility model is achieved in that a kind of curing catalyst microcapsule ball of resol, it is characterized in that: it is to be made of macromolecule glue softgel shell and interior curing catalyst capsule-core thereof; Described macromolecule glue softgel shell is the soft shell body of being made by sodium alginate capsule or gelatine capsule or polyvinyl alcohol; Described curing catalyst capsule-core is that vanay or propylene carbonate ester or diethyl carbonate are made; Described macromolecule glue softgel shell is sphere or round bar shape.
Owing to adopt such scheme: can prolong the working life after agent and PF mixed with resin are urged in curing, improve the efficient of the resin-bonded sheet material of PF in the wood-based panel industry.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 the utility model exemplary embodiments synoptic diagram.
Among the figure: 1 curing catalyst capsule-core, 2 macromolecule glue softgel shells.
Present embodiment comprises curing catalyst capsule-core 1 and macromolecule glue softgel shell 2, as shown in Figure 1, wherein: curing catalyst capsule-core 1 is that a kind of promotion PF resin and sheet material agglutinating solidify, thereby, improve the production efficiency of wood-based plate, cut down the consumption of energy, common curing catalyst capsule-core 1 has vanay, propylene carbonate, diethyl carbonate etc.
Macromolecule glue softgel shell 2 is sphere or round bar shape soft shell bodies of being made by sodium alginate capsule or gelatine capsule or polyvinyl alcohol, comprises curing catalyst capsule-core 1 in this macromolecule glue softgel shell 2.
