Abstract

The invention belongs to production of plywood and particularly relates to a special filler for plywood glue. The special filler is prepared by uniformly mixing effective dosages of pine bark powder, rice hull powder or peanut shell powder, attapulgite or quartz powder, puffed corn starch, sweet potato seedling powder or sweet potato flour residue, powdery preservative and Junbiqing, and the problems of high cost, bad color and bad water resistance in the prior art are solved in the invention. The special filler for plywood glue has the advantages of wide raw material source, reasonable compatibility, low cost and capability of removing formaldehyde and reinforcing water resistance of plywood, and the like.

Description

The plywood glue filling agent special
Technical field
The invention belongs to the production of glued board, refer to a kind of plywood glue filling agent special especially.
Background technology
At present China's artificial liner enterprise is at first wanted impregnation making core-board, glued board, building template with in the process of glued board, and so-called impregnation is exactly to dose a large amount of weighting agents in urea formaldehyde glue, is convenient to the purpose of gluing on the veneer to reach thickening.Be used at present mainly selecting whole meal flour for use as the material of weighting agent, the addition of flour mainly determines that according to the quality (referring to mainly water content how much) of glue general glue per ton is dosed the flour amount between 30%-40%.
Publication number is to disclose a kind of high efficiency filling material for veneer board in 1820914 the patent documentation, be to utilize the meal that wood powder, albumen blood meal etc. are organic and inorganic mineral mixes, play thickening power with organobentonite, inorganic bentonite and organic cellulose, play filling effect with wood powder, work to increase viscosity with amonang powder, water glass and albumen blood meal, and water glass and albumen blood meal absorb the effect of formaldehyde in addition.Problems such as above-mentioned prior art exists albumen blood meal cost height, and the weighting agent color of making is bad, and water glass (bubble flower alkali) does not allow to do carton as requested, and the water tolerance of weighting agent itself is relatively poor.
Summary of the invention
The object of the present invention is to provide a kind of water tolerance strong, can have formaldehyde absorptive function, plywood glue filling agent special that cost is lower.
Overall technology design of the present invention is:
The plywood glue filling agent special, make after being mixed evenly by the component of following unit mass part:
Cortex Pini powder 250-350 powdered rice hulls or peanut hull meal 150-300 rod soil or silica powder 120-200 expanded corn starch 350-400 sweet potato vine powder or pachyrhizus granulated slag 100-180 powdery sanitas 18-35 bacterium be 5-15 clearly.
Concrete technical conceive of the present invention also has:
For further improving weighting agent uniformity coefficient and resolution in glue, satisfy it simultaneously and can be used on the bonding of veneer, optimized technical scheme is.The Cortex Pini powder, powdered rice hulls or peanut hull meal, the granularity of sweet potato vine powder or pachyrhizus granulated slag is not less than 120 orders, and the granularity of excellent soil or silica powder is not less than 325 orders, and the granularity of expanded corn starch is not less than 200 orders.
Selecting for use of powdery sanitas can be adopted multiple starting material, wherein comparatively preferably adopts Sodium Benzoate.
The effect of each component is among the present invention:
Because adopting the Cortex Pini powder among the present invention is main making raw material, can increase the toughness except wherein containing more wood fibre, wherein also contain tannin and rosin, tannin can be released under the condition of high temperature, because tannin has the natural aldehyde effect of going out, so effectively PARA FORMALDEHYDE PRILLS(91,95) is removed.Rosin can effectively improve its water tolerance in the molded process of glued board elevated temperature heat; Rod soil and silica powder in the stopping composition mainly contain compositions such as silicon-dioxide, aluminium sesquioxide, also can further improve the water tolerance of stopping composition.Powdered rice hulls and peanut hull meal etc. contain fiber, can increase the toughness of stopping composition.Expanded corn starch mainly increases the viscosity of glue.The main effect of sanitas (Sodium Benzoate) is to prevent that starch from becoming rotten.Bacterium must be clear main effect be to prevent that powder and slag class material are mouldy.
The urea-formaldehyde glue that adopts stopping composition of the present invention to add detects through national wood-based plate and Bamboo and wood product quality supervision and test center, the burst size of its free formaldehyde is 0.07%, meet among the GB/T14732-2006 should≤0.3% for the burst size of free formaldehyde requirement, adopt the glued board of the urea-formaldehyde glue preparation of adding stopping composition of the present invention through the check of Hebei province's wood-based panel product quality monitoring testing station (Wenan), detected result is 2440.0-2440.5mm for the detection length of censorship glued board, width is 1220.0-1220.5mm, thickness is 9.0mm, tolerance 0.2-0.4mm/m is directly spent at the edge, squareness tolerance is 0.3-0.4mm/m, angularity is 1.0%, water ratio is 9.1%, bonding strength average out to 0.79MPa, burst size of methanal is 1.0mg/L, and the detected result of above leading indicator all meets the relevant requirements of GB/T9846-2004.
The substantive distinguishing features that the present invention is obtained and significant technical progress are:
Whole preparation technology of the present invention is simple, and raw material sources are extensive, compatibility is reasonable and cost is lower, selects for use the Cortex Pini powder as main raw material, can make product possess the function of certain removal formaldehyde, and the while can strengthen the water tolerance of glued board.
