Environment-friendly surface glue film dry-pressing resin and application method thereof

Abstract

The invention relates to environment-friendly surface glue film dry-pressing resin for digital color printing paper and a method for preparing an environment-friendly surface dry-pressing transparent glue film material by using the environment-friendly surface glue film dry-pressing resin. The environment-friendly surface film dry-pressing resin is prepared from the following raw materials in parts by weight: 100 parts of melamine resin, 0.18-0.25 part of a penetrant, 0.08-0.12 part of a release agent and 0.12-0.18 part of a curing agent. The environment-friendly surface glue film dry-pressing resin is utilized to prepare the environment-friendly transparent surface glue film material, then the digital color printing paper with different sizes is composed and combined and neatly laid on among complete bonding materials, and can be firmly combined with a base material through the permeation of the dry-pressing resin, and finally a personalized decorative product is formed. The finished product is beautiful in pattern color, meets the requirement of human on the combination of beauty and art products, and meanwhile has the advantages of being high in definition, free of distortion and resistant to fading.

Description

(1) Technical field

[0001] The invention relates to an environment-friendly dry-pressed surface layer resin for color digital printing paper, and a method for preparing an environment-friendly surface dry-pressed transparent film material by using the environment-friendly surface layer dry-pressed resin. (2) Background technology

[0002] The traditional adhesive film paper pressing and pasting veneer process cannot be used for color digital printing paper. Since the pattern of digital printing paper is clear and the pattern size can be customized at will, it can well make up for the lack of personalization of decorative paper in personalized fields such as sliding doors, painted floors, painted decorations, and decorative paintings. However, the production process of ordinary decorative paper dipped in glue Only fixed length and width film paper can be cut in batches. Due to individual characteristics such as size, digital printing paper cannot be cut in batches after dippi...

Embodiment 1

[0024] 1. Preparation of melamine resin:

[0025] (1) Put 100kg of formaldehyde and 40kg of water into the reactor, add 8kg of modifier, stir evenly, and adjust the pH to 9.0-10 with 30% sodium hydroxide by mass fraction;

[0026] (2) 78kg of melamine is dropped into the reactor, and the temperature is raised to 94-96°C for 70min at a rate of 1.5°C / min;

[0027] (3) When the ratio of resin to water is detected to be 1:2.6-3.0 at 25° C., the temperature is lowered to 40° C. and discharged to obtain the melamine resin.

[0028] The parameters of the prepared melamine resin are as follows: the viscosity is 0.35-0.4 Pa·s, the water mixing ratio is 1:1.8-2.0, the density is 1.18-1.2 g / cm3, and the solid content is 48-52%.

[0029] 2. Preparation of environment-friendly transparent surface dry-pressed film material

[0030] (1) Glue compounding: melamine resin 100kg, penetrant 0.2kg, release agent 0.1kg, curing agent 0.15kg, mix and stir well, 100℃ water-soluble curing time 6-8min...

Embodiment 2

[0036] 1. Preparation of melamine resin:

[0037] (4) drop the water of 100kg of formaldehyde and 45kg in the reactor, add the modifying agent of 8.5kg, stir;

[0038] (5) 75kg of melamine is dropped into the reactor, and the temperature is raised to 94-96°C for 90min at a rate of 1.5°C / min;

[0039] (6) When the volume ratio of the resin to water is detected to be 1:2.0-2.5 at 25°C, the temperature is lowered to 40°C and discharged to obtain the melamine resin.

[0040] The parameters of the prepared melamine resin are as follows: the viscosity is 0.30-0.34Pa·s, the water ratio is 1:1.3-1.5, and the density is 1.17-1.18g / cm 3 , solid content of 44 to 46%.
