Description
Technical field
The present invention relates to a kind of aqueous adhesive and preparation method thereof, be particularly for a kind of wood pencil environment-friendly type high performance water tackiness agent and preparation method thereof.
Background technology
In traditional pencil manufacturing processed, generally pencil-lead is squeezed in pencil groove in case pencil-lead skids off from pencil timber by applying external force, but this sampling technology often causes the pen core in pencil groove to be occurred cracking by the penholder of pinch off or pencil, thereby causes a series of quality problems.In order to address this problem, at present conventional method be utilize aqueous adhesive by pencil-lead together with bonding wood materials, concrete operation method is: water-based pencil-lead tackiness agent is coated in the groove on pencil slat material and on sheet material, then pencil-lead is put into groove, again upper and lower two boards material is merged, by clamp, after tackiness agent drying and forming-film, enter again the operations such as plane bar below, moulding, japanning.
Existing its main component of pencil-lead aqueous adhesive of current domestic use is polyvinyl acetate emulsion (PVAc emulsion), although polyvinyl acetate emulsion has good bond effect to timber, but its water tolerance and wet fastness are poor, easily moisture absorption, film-forming temperature is high, under high temperature, cohesive strength decline produces creep, to the cohesive strength deficiency of the especially high category-B black of all kinds of pen cores pen core.In addition,, due to loss of properties on aging after PVAc emulsion drying and forming-film, even if the pencil of making also easily occurs the phenomenons such as slide core after placing at normal temperatures for some time, cause the entirety of pencil final product quality to decline.
Summary of the invention
The object of the present invention is to provide a kind of wood pencil environment-friendly type high performance water tackiness agent, make it have water tolerance and good weatherability, creep resistance is strong, at cohesive strength high between timber and timber, between timber and pencil-lead.
