Description
Technical field
The present invention relates to a kind of production technology of the short cycle dipping paper of hot pressing.
Background technology
At present, the surface of furniture generally one layer of dipping paper of patch, so as to improve the glossiness of furniture surface so that furniture is taken a fancy to
Go more attractive in appearance, for the conventional dipping paper of in the market in production, the cycle is longer, low production efficiency, causes production cost higher, and
Can not meet the needs of market, its main cause is conventional curing agent because low pressure short cycle dipping glue is very sensitive to pH value,
Quick production can not be realized.
The content of the invention
In view of the above-mentioned problems, the invention provides a kind of production technology of the short cycle dipping paper of hot pressing, dipping is greatly shortened
The production time of paper, so as to effectively solve the problems, such as in background technology.
The technical solution adopted by the present invention is：
A kind of production technology of the short cycle dipping paper of hot pressing, comprises the following steps：
(1) one leaching：Body paper is completely immersed in impregnation in an impregnation water, obtains single-steeping paper；
(2) first drying：Single-steeping paper is dried by 120-150 DEG C of baking oven, drying time 50-80
Second so that the volatile matter of single-steeping paper is controlled in 15-20%；
(3) it is coated with：Back of the body painting is carried out to single-steeping paper with glue coating first, then glue coating is coated on and once soaked
Stain recto, double-steeping paper being obtained, described glue coating includes melamine resin, curing agent and releasing agent,
Described curing agent uses latent curing agent, pH 7.0-8.0, solid content 20-30%, and the viscosity at 20 DEG C is
12.5-13.55, the pH of the releasing agent is 7.0-8.0, and solid content 30-40%, the quality of the curing agent is melamine
The 0.5-1.5% of formaldehyde resin, the quality of the releasing agent are the 0.1-0.3% of melamine resin；
(4) secondary drying：Double-steeping paper is dried by 150-160 DEG C of baking oven, drying time is 5-8 points
Clock so that the volatile matter of double-steeping paper is controlled in 6.5-7.5%, procuring degree：30%~50%；
(5) cut out：After double-steeping paper is down into room temperature, it is cut out according to specification.
Preferably, a described impregnation water includes melamine resin adehsive, bleeding agent and curing agent, described curing agent
Using latent curing agent, pH 7.0-8.0, solid content 20-30%, the viscosity at 20 DEG C is 12.5-13.55, described
The quality of curing agent is the 0.5-1.5% of melamine resin, and the pH of the bleeding agent is 7.0-8.0, solid content 30-
40%, the quality of the bleeding agent is the 0.1-0.3% of melamine resin.
Preferably, the pH of the impregnation water and glue coating is 7.5-7.6, the viscosity at 20 DEG C is 13.5-
15.55。
Preferably, in the step (1) time of a leaching be 9-11 minutes, the time 4-5 being coated with the step (3)
Minute.
The present invention selects latent curing agent, and so as to reduce the susceptibility of an impregnation water and glue coating to pH, the back of the body applies
Process can prevent glue coating from the two sides of paper while penetrate into, and cause core bubble to be not easy to discharge, it is necessary to using primary coat,
To ensure the impregnating effect of paper, back of the body paint roller should be reversed, and the cornerite of paper and primary coat roller should be adjusted, and back of the body painting amount is carried on the back with its dipping
Face, which somewhat soaks, to be advisable.
