Embodiment 1

[0015] Embodiment 1, this embodiment provides a decorative base paper reinforcing agent and a preparation method thereof. First, prepare a high-efficiency adhesive as follows: Weigh 2g of sodium polyacrylate, 20g of polyvinyl alcohol, and 5g of styrene-acrylic emulsion, mix them, and react at 120°C for 3 hours; after the reaction, cool down to 80°C, and then add 5g of methacrylic acid, React for 6 hours, then cool to room temperature to obtain a milky white high-efficiency adhesive.

[0016] The substances in the reinforcing agent are formulated as follows by weight fraction (excluding water and pH regulator): 90 parts of 95-grade GCC pigment, 1 part of defoamer, 2 parts of latex, 1 part of ammonia water, and 5 parts of high-efficiency adhesive. The preparation steps are as follows: add the pigment into the batching tank, which contains enough water to disperse the pigment, disperse at a high speed for 20 minutes, and the speed of the high-speed dispersion is 800 rpm to obtain...

Embodiment 2

[0017] Embodiment 2, this embodiment provides a decorative base paper reinforcing agent and a preparation method thereof. First, prepare a high-efficiency adhesive as follows: Weigh 2g of sodium polyacrylate, 38g of polyvinyl alcohol, and 10g of styrene-acrylic emulsion in turn, mix them, and react at 120°C for 3 hours; after the reaction, cool down to 70°C, then add 5g of methacrylic acid, and react 5 hours, and then cooled to room temperature to obtain a milky white high-efficiency adhesive.

[0018] Each substance in the reinforcing agent is prepared as follows according to the weight fraction: 90 parts of 95-grade GCC pigment, 1 part of defoamer, 3 parts of latex, 1 part of ammonia water, and 10 parts of high-efficiency adhesive. The preparation steps are: add the pigment into the batching tank, disperse at a high speed for 25 minutes, and the speed of the high-speed dispersion is 1000 rpm to obtain the mixture a; add the high-efficiency adhesive and latex to the water, re...

Embodiment 3

[0019] Embodiment 3, this embodiment provides a decorative base paper reinforcing agent and a preparation method thereof. First, prepare a high-efficiency adhesive as follows: Weigh 5g of sodium polyacrylate, 38g of polyvinyl alcohol, and 10g of styrene-acrylic emulsion, mix them, and react at 120°C for 2 hours; after the reaction, cool down to 75°C, then add 5g of methacrylic acid, and react 5.5 hours, and then cooled to room temperature to obtain a milky white high-efficiency adhesive.

[0020] The substances in the reinforcing agent are prepared as follows according to the weight fraction: 100 parts of china clay, 1 part of defoamer, 2 parts of latex, 1 part of ammonia water, and 5 parts of high-efficiency adhesive. The preparation steps are: add the pigment into the batching tank, disperse at a high speed for 20 minutes, and the speed of the high-speed dispersion is 1000 rpm to obtain the mixture a; add the high-efficiency adhesive and latex to the water, react at 120°C fo...

Abstract

The invention relates to the field of chemical engineering, in particular to a decorative base paper enhancer and a preparation method thereof. The enhancer comprises pigment, efficient adhesive, ammonia water, latex, defoaming agent and deionized water. The preparation method includes the following steps of adding pigment into a compounding pool to be dispersed at high speed, adding efficient adhesive and latex to water to conduct reaction at a temperature of 110-130 DEG C and to be mixed and dispersed for 15-20 min at high speed, adding ammonia water, adjusting PH with sodium hydroxide, and adding defoaming agent to be stirred for 10-25 min at low speed to obtain the enhancer product. The enhancer is an environment-friendly auxiliary, and the prepared decorative base paper enhancer is added to decorative base paper, so the addition of other chemical auxiliaries is reduced, and the shielding performance of titanium dioxide is improved. Due to the addition of the enhancer special for decorative paper, the addition of other auxiliaries is reduced, papermaking bleach can be more easily processed and reused, and water consumption is lowered. Due to the addition of pigment, wood pulp consumption can be reduced, and cost is saved.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a decorative base paper reinforcing agent and a preparation method thereof. Background technique [0002] Decorative base paper is a special paper that is widely used in construction, decoration, home veneer, floor veneer, etc. Its main function is to provide pattern decoration and prevent the bottom glue from seeping out to avoid bottom penetration. However, in the traditional process of producing decorative base paper, the addition of titanium dioxide, calcium carbonate, china clay and other fillers and pigments will cause insufficient paper strength and even paper breakage. On the other hand, the addition of a large number of fillers and additives makes white water difficult to handle, causing serious ion accumulation, resulting in abnormal production and increasing production costs. Contents of the invention [0003] The invention provides a decorative base paper strengthe...
