Abstract
The invention relates to an environmentally-friendly synergic additive for a wood fiber density board, which is characterized by comprising the following components in part by weight: 1 to 5 parts of tert-butyl hydroperoxide, 1 to 50 parts of styrene and 1 to 50 parts of 2-ethylhexyl acrylate. The environmentally-friendly synergic additive is suitable for the wood fiber density board, and can reduce cost, improve the water repellency, abrasive resistance and the like of the density board, and particularly can reduce the discharge amount of formaldehyde and improve environmentally-friendly quality greatly.
Description
Technical field
The invention belongs to the auxiliary material in a kind of board materials production, specifically is a kind of additive during the wood-fibred density board is produced, and this additive can play the water proofing property and the stronger effect of robustness that make the wood-fibred density board with for traditional additive paraffin wax.
Background technology
Wooden boards is an indispensable material in the social production life, and along with expanding economy, the demand of wooden boards is also increasing.Because timber is in short supply, solid wood board costs an arm and a leg, and is difficult to satisfy the demand; And the solid wood material also has some shortcomings, and is generally not very good on water proofing property and robustness.For many years, people produce a kind of wood-fibred density board, replace the solid wood plate, on saving timber, have played very large effect, and also have been superior to the solid wood plate on its some performance.The production technology of used wood-fibred density board generally is: various Wood Processing are become wood chip, and------wood chip is pulverized abrasive dust, and---carry and the interpolation additive---wood-fibred gets into the dram oven dry---pressing plate is shaped chip steaming through conveyance conduit.Generally in the pipeline process wood fiber powder to add various additives: From A Chuo and urea synthesis of urea-formaldehyde glue, and now the production of wood fiber MDF process, adding paraffin is to improve the waterproof sheet, however, Because the characteristics of paraffin difficult dissolved, usually in the form of pellets in MDF, wood fiber MDF waterproof performance is often less than ideal.Therefore, need to propose a kind of novel additive, substitute paraffin wax, thereby improve the water proofing property and other performances of wood-fibred density board.
Summary of the invention
To the objective of the invention is in order solving the problems of the technologies described above, a kind of wood-fibred density board synergy environmental-protection additive and using method thereof to be provided, this synergy environmental-protection additive is in wood-fibred density board production technology; Replace paraffin wax, method for using is easy, can improve the water resistance of wood-fibred density board greatly; And make the robustness of density board stronger; And can practice thrift cost, and reduce the discharge capacity of formaldehyde, improve environment-friendly quality.
The objective of the invention is to realize through following technical scheme:
A kind of wood-fibred density board synergy environmental-protection additive is characterized in that being made up of the composition of following parts by weight:
TBHP 1-5
Styrene 1-50
Acrylic acid-2-ethyl caproite 1-50
Preferably, this additive also comprises the butyl methacrylate of 1-50 weight portion.
A kind of method for using of wood-fibred density board synergy environmental-protection additive comprises described additive one of in the claim 1,2 is added in the wood-fibred density board production technology.
Chip steaming in said wood-fibred density board production technology or wood chip are pulverized abrasive dust, wood fiber powder in the dram supplying step, add additive through conveyance conduit.
The use amount of said additive is: 0.5-20 kilogram/cubic meter density board.
The effect of each composition in the scheme: TBHP is an initator, causes each monomer composition and wood-fibred and forms polymerization, with the urea-formaldehyde glue crosslinking curing in other additives; Styrene improves hardness, adhesive force, anti-stain characteristic and the resistance to water of wood-fibred density board; Acrylic acid-2-ethyl caproite improves humidity resistance, pliability, the cold-resistant anti-cracking behavior of density board, improves percentage elongation; Butyl methacrylate improves solvent resistance, gloss retention and the UV resistant performance of density board.
Beneficial effect of the present invention is:
1. cost is low, and the batching of additive of the present invention is easy to get, and price is low, and easy to use, does not increase or change the equipment of existing production technology;
2. because additive of the present invention in process of production, is changed additive with wood-fibred and its and produced useful chemical reaction, make water resistance and the big raising of firm performance with the wood-fibred density board of Additive Production of the present invention.
3. the wood-fibred density board of using Additive Production of the present invention not only its water resistance and firm performance improves greatly; And the volatile quantity of formic acid significantly reduces; Thereby improved the environmental-protecting performance of density board greatly, be used for family's indoor decorating and be particularly conducive to the healthy of people.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the present invention is described further:
Embodiment 1: a kind of wood-fibred density board synergy environmental-protection additive is that the composition by following parts by weight constitutes:

Embodiment 4: a kind of wood-fibred density board synergy environmental-protection additive is that the composition by following parts by weight constitutes:
TBHP 1
Styrene 1
Acrylic acid-2-ethyl caproite 1
Butyl methacrylate 1
Embodiment 5: a kind of wood-fibred density board synergy environmental-protection additive is that the composition by following parts by weight constitutes:
TBHP 5
Styrene 50
Acrylic acid-2-ethyl caproite 50
Butyl methacrylate 50
Embodiment 6: a kind of wood-fibred density board synergy environmental-protection additive is that the composition by following parts by weight constitutes:

Styrene 25
Acrylic acid-2-ethyl caproite 25
Butyl methacrylate 25
Take out the batching of each required composition according to the proportioning of above-mentioned prescription; At normal temperatures together, and stir and stumble evenly with the batch mixes of each composition.
One of in the foregoing technical scheme described additive add to wood-fibred density board production technology in.Specifically be in the chip steaming step in said wood-fibred density board production technology, add additive, additive of the present invention is sprayed in the chip steaming cylinder through jet pipe through conveyance conduit.Because the pressure in the general density board production technology in the boiling cylinder is generally 8 atmospheric pressure, in the present embodiment, the ducted pressure of spray feed additive of the present invention is 10 atmospheric pressure.Consumption is 1 kilogram of/cubic metre density board.
The effect of the foregoing description is very good, and the wood-fibred density board of being produced all meets or exceeds relevant each item standard through the check of national authorities.
