Abstract
The invention discloses a camellia fruit shell powder additive which contains camellia fruit shell powder and a thickening agent, wherein the camellia fruit shell powder and the thickening agent are uniformly mixed, and the addition amount of the thickening agent is 1-5 percent of the weight of the camellia fruit shell powder. The invention also discloses a preparation method and a using method applying to man-made planks of the camellia fruit shell powder additive. The biomass additive prepared by mixing the camellia fruit shell powder with the thickening agent effectively increases the bonding strength of a wood adhesive and reduces the formaldehyde emission content of planks, the production cost is greatly reduced compared with that of a similar product using flour as the additive, and the product performance is more superior than that of the similar product. The preparation method for the camellia fruit shell powder additive is simple, non-toxic, green and environment-friendly, has strong operability, can cause the utilization rate of camellia fruit shells to achieve 100 percent, and largely increases the utilization value of the camellia fruit shells; the camellia fruit shell powder additive can be widely used for preparing wood furniture, blockboards and various kinds of wood floor base materials.
Description
Technical field
The invention belongs to wood adhesive additive technology field, be specifically related to a kind of oil-tea camellia husks flour additive agent that improves the wood adhesive performance and preparation method thereof.
Background technology
In the mankind's daily life life, the timber material that is absolutely necessary, especially the modern yearns for nature, the multiplex timber of outdoor booth corridor and interior decoration.Yet the arboreal growth cycle is slow, on market, timber resources is in short supply, therefore, generally with artificial timber board, substitute solid wood, the preparation major part of artificial timber board is to utilize the adhesive made of synthetic resin compacting to form, and domestic adhesion agent for wood industry is to adopt " three aldehyde " class (urea aldehyde, phenolic aldehyde, melamino-formaldehyde class) tackiness agent more than 90%.The shortcoming of this type of tackiness agent is to exist free formaldehyde to discharge, and free formaldehyde can be dispersed in room by Long-term Free, causes free formaldehyde in room to limit the quantity of and contaminate environment over regulation, endangers other people healthy." three aldehyde " class tackiness agent will add the flour impregnation in applying glue as last, play the purpose of the easy applying glue of thickening and raising adhesive solid content, but to improving the tackiness agent water tolerance and reducing burst size of methanal effect not obvious, and flour belongs to edible article, price is more expensive, is not suitable for industrial additive.Biomass additive is to utilize the agricultural industrial wood waste, as oil-tea camellia husks etc., is crushed to certain fineness, then adds the thickening material blend formulated, and alternative flour plays the easy applying glue of thickening and improves the purpose of adhesive solid content.The oil-tea camellia husks powder contains the compositions such as natural macromolecular material xylogen, after being crushed to certain fineness and tackiness agent blend, can be in conjunction with free formaldehyde in the artificial timber board hot pressing, synthetic Polyphenols reticulated structure, the burst size of methanal of reduction sheet material when improving tackiness agent gummed performance.The biomass additive main component is the agricultural industrial wood wastes, low price, and superior performance, environmental protection, find rational application approach to oil-tea camellia husks, improves its utility value, significant.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly can improve the wood adhesive solid content, reduce the low cost that the tackiness agent Free Aldehyde discharges, additive of environmental protection and preparation method thereof, the additive of preparation can be used for the modulation of " three aldehyde " resin adhesive, for the preparation of woodwork furniture, core-board and all types of wood floor base material.
The technical solution adopted in the present invention is:
A kind of oil-tea camellia husks flour additive agent, comprise oil-tea camellia husks powder and thickening material, and the oil-tea camellia husks powder mixes with thickening material, the 1%-5% that the add-on of thickening material is oil-tea camellia husks opaque amount.
In order to obtain better technique effect, the smashing fineness of above-mentioned oil-tea camellia husks is the 100-300 order; Above-mentioned thickening material is one or more combinations in starch, methylcellulose gum, Xylo-Mucine.
The present invention also provides a kind of preparation method of oil-tea camellia husks flour additive agent, and step is:
(1) clean the oil-tea camellia husks surface impurity, drier, pulverizing;
(2) take thickening material, the 1%-5% that the add-on of thickening material is oil-tea camellia husks opaque amount;
(3) by oil-tea camellia husks powder and the thickening material blend of pulverizing, stir, make the oil-tea camellia husks flour additive agent that improves the wood adhesive performance.
In order to obtain better technique effect, oil-tea camellia husks water flushing at normal temperatures surface impurity in above-mentioned steps (1); In above-mentioned steps (1), 63 ℃ of lower forced air dryings of oil-tea camellia husks to water ratio is pulverized after 8% again; The smashing fineness of above-mentioned oil-tea camellia husks is the 100-300 order; Above-mentioned thickening material is one or more combinations in starch, methylcellulose gum, Xylo-Mucine.
The present invention also provides a kind of oil-tea camellia husks flour additive agent to be applied to the using method of artificial timber board, the steps include:
(1) take the oil-tea camellia husks flour additive agent, the 5%-20% that the add-on of oil-tea camellia husks flour additive agent is the wood adhesive quality;
(2) oil-tea camellia husks flour additive agent and wood adhesive are mixed;
(3) artificial timber board applying glue;
(4) the sham wood slab after applying glue is sent into to thermocompressor hot-forming, make artificial timber board after hot pressing.
In order to obtain better technique effect, 110～140 ℃ of above-mentioned hot-forming temperature, hot pressing time/thickness of slab is 0.8～1.0min/mm, hot pressing pressure 0.8～1.0MPa; Above-mentioned thickness of slab is thickness of slab before hot-press gluing; Above-mentioned wood adhesive is one or more combinations in urea-formaldehyde resin adhesive, synvaren, melamino-formaldehyde class tackiness agent.
The biomass additive that oil-tea camellia husks powder and thickening material are mixed with can effectively improve the bonding strength of wood adhesive and reduce the burst size of methanal of sheet material, the product that the more similar use flour of production cost is additive reduces significantly, and product performance are more superior than it, the oil-tea camellia husks addictive preparation method is simple, nontoxicity, environmental protection, workable, can make the utilization ratio of oil-tea camellia husks reach 100%, improve largely its utility value.
