Abstract
The invention discloses a kind of production method of the ecological dipping paper of science and technology.This method is carried out successively according to the step of preparing urea-formaldehyde glue, prepare triamine glue, single-steeping, first drying, coating, double-steeping, secondary drying, cutting, inspection, packaging, storage, the ecological dipping paper of science and technology produced using the method for the present invention, the veneer that wood skin can be replaced completely is used for ecological board makes, the harmful effect brought during house ornamentation using wood skin is eliminated, the total quality level of ecological board is improved.Compared with dipping paper prepared by traditional urea-formaldehyde glue and triamine glue, its shock resistance, anti-wear performance are high, free formaldehyde content is low, ecology dipping paper is smooth, glue is evenly distributed, complete covering can be realized to plate grain, eliminates and reveals the exact details and carbonization phenomenon, improve product qualification rate and service life.
Description
Technical field
The present invention relates to a kind of production method, a kind of production method of the ecological dipping paper of science and technology is concretely related to.
Background technology
At present, house ornamentation market have furniture made to order it is many be processed making as main material using ecological boards, and ecological board
Veneer improves the flatness and covering effect on surface using wood skin, and wood skin plays very crucial to the Integral decoration effect of sheet material
Effect.Due to the natural characteristic of timber, wood skin has the defect that some are difficult to overcome, and lumber fibre is only in arboreal growth direction
（Longitudinal direction）There is pulling force, laterally almost caused in use, it may appear that the situation of sheet material longitudinal cracking without pulling force.Secondly
The lumber fibre surface depression of itself, during overlaying, it may appear that local to overlay unreal, and shows as plate face carbonization, influence
The selection of plate face pattern, can only select light colour pattern, it is impossible to select dark colour, cause pattern selection to be limited to.Further, due to
Itself the scar knot and black line of wood skin be difficult to be completely covered by and surface tension limitation, occur reveal the exact details phenomenon and table during overlaying
Surface aesthetic effects are had a significant impact by face out-of-flatness, and bad using effect is brought to house ornamentation.In addition in the production of wood skin,
Timber is also largely used, sizable adverse effect and waste are all produced to the ecological environment and the forest reserves of country.
Requirement with people to quality of the life is improved constantly, and has higher quality requirements, ecology dress to fitment material for family
The quality of plaque is badly in need of improving, and wood skin quality is the key of improving quality, and the present invention lacks aiming at wood skin
Fall into, by studying dipping method, produce a kind of ecological dipping paper of science and technology, completely instead of wood skin, to eliminate the bad defect of wood skin,
Improve the total quality level of ecological board.
The content of the invention
For problems of the prior art, the invention provides a kind of production method of the ecological dipping paper of science and technology.Should
The veneer that product made from method can replace wood skin completely and be used for ecological board is made, and wood skin institute band is used during elimination house ornamentation
The harmful effect come, improves the total quality level of ecological board.
The present invention uses following technical scheme：
A kind of production method of the ecological dipping paper of science and technology, it is characterised in that it comprises the following steps：
（1）Prepare urea-formaldehyde glue：2500 kilograms of formaldehyde is put into reactor, 15 kilograms of accelerator is added and uses sodium hydroxide
Solution regulation pH value is 7-8, is then heated to after 86-87 DEG C and stops heating, is incubated 20min；The formic acid for adding 20% in three times is adjusted
PH value is saved to 4-4.6, time interval is 5-10min, and temperature is risen to after 93-96 DEG C, about 90 minutes automatically, and glue is put into 35
Cloud point is detected in DEG C water, occurs adding 35 kilograms of accelerator during white haze, beginning after being then 5-8 with sodium hydroxide regulation pH value
Cooling, adds 550 kilograms of urea, 350 kilograms of water, then cool to 35 DEG C and produce after temperature is down to 60 DEG C；
（2）Prepare triamine glue：1000 kilograms of formaldehyde is put into, 500 kilograms of water adjusts pH value to addition after 9.5 to be modified with caustic soda
70 kilograms of agent, 775 kilograms of melamine, then heat temperature raising；92-93 DEG C is warming up to, stops heating, insulation to the water-soluble ratio of glue
Reach 1：1.3,40 DEG C are cooled at once produces；
（3）Single-steeping：Body paper is completely immersed in glue, hardening time 10min, procuring degree is 40-50%；
（4）First drying：Body paper after single-steeping is dried 60~70 by 130 DEG C~135 DEG C of hot-air oven
Second so that the single-steeping glue volatile content in impregnated carrier is adjusted to 12%~14%；
（5）Coating：Use step（4）Obtained triamine glue is uniformly coated on impregnated carrier tow sides, hardening time
6min, procuring degree is in 35-40%；
（6）Secondary drying：Impregnated carrier after coating is dried into 5-7min by 135 ~ 145 DEG C of hot-air oven, after drying
The content of volatile matter is 7.5%；
（7）The impregnated carrier that secondary drying is down to after room temperature is cut according to specification, is examined, packed, is put in storage.
In above-mentioned production method, the step（1）Middle accelerator is polystyrene：Melamine：1,2- dimethyl miaows
Azoles：Sodium alkyl benzene sulfonate is according to 15：20:3:0. 3 ratio is made.
In above-mentioned production method, the step（4）Middle modifying agent is zinc sulfate：Hexa：Hydroxypropyl methyl
Cellulose：Polyvinyl alcohol：Hydroxyl-terminated injecting two methyl siloxane is according to 12.5:1:75:250：25 ratio is made.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention uses exclusive glue formula, and dipping glue uses urea-formaldehyde glue, and it is added by polystyrene, melamine in being formulated
Amine, 1,2- methylimidazoles, the accelerator of 4 kinds of composition compositions of sodium alkyl benzene sulfonate, each component synergy fully ensure that glue
Homogeneous impregnation, infiltration, film forming, add adhesive strength, shorten hardening time, improve the water resistance of product, toughness and anti-
Ageing properties.Coating process in production method of the present invention uses special triamine glue, and it is used in being formulated with zinc sulfate, six Asias
Tetramine, hydroxypropyl methyl cellulose, polyvinyl alcohol, the modifying agent of 5 kinds of composition compositions of hydroxyl-terminated injecting two methyl siloxane, by
Can be with formaldehyde in hexa therein, hydroxypropyl methyl cellulose, polyvinyl alcohol, hydroxyl-terminated injecting two methyl siloxane
Chemically reacted with melamine hydroxymethyl derivative, resin structure can be changed, decline crosslink density, fragility reduces, tough
Property increase, and zinc sulfate and being used in combination for hydroxyl-terminated injecting two methyl siloxane can dramatically increase the stability of triamine glue, its
Stability under high or low temperature environment is high；Hydroxyl and amino can react with free formaldehyde simultaneously, reduce free formaldehyde
Content, thus when products obtained therefrom free formaldehyde content it is low, lifted environmental-protecting performance；Impact resistance strengthens, and covering power is high, prevents old
Change, do not ftracture.In addition, the present invention passes through corresponding impregnation technology parameter optimization, it is ensured that the smooth and glue point of ecology dipping paper
Cloth is uniform, to realize the covering to plate grain, and elimination is revealed the exact details and carbonization phenomenon, expands the selection face of ecological board pattern, adjustment
Paper stress is impregnated, crashworthiness hit intensity is lifted, produces brand-new ornament materials, to realize the replacement renewal to existing product, is disappeared
Except defect, improving performance.
