Embodiment 1

[0015] Such as figure 1 Shown is a kind of preparation technology of composite bubble gum paper sheet on the surface of paper-faced gypsum board, specifically comprises the following steps:

[0016] Step 1. Place the gypsum board on the table of the high-temperature and high-pressure heat press, select foam paper with specific colors and patterns according to the customer group, and then place the selected foam paper on the gypsum board;

[0017] Step 2. Set the pressure value, temperature, and hot-pressing time of the steel film of the hot-press machine as required: the pressure range is 288 tons, the temperature is 160°C, and the hot-pressing time is 30 seconds;

[0018] Step 3. Start the hot press to heat the steel film. When the temperature of the steel film reaches the set temperature, the table of the hot press drives the gypsum board and the foam paper to rise. When the gypsum board and the foam covering it When the adhesive paper sheet is close to the steel film at hi...

[0021] Such as figure 1 Shown is a kind of preparation technology of composite bubble gum paper sheet on the surface of paper-faced gypsum board, specifically comprises the following steps:

[0022] Step 1. Place the gypsum board on the table of the high-temperature and high-pressure heat press, select foam paper with specific colors and patterns according to the customer group, and then place the selected foam paper on the gypsum board;

[0023] Step 2. Set the pressure value, temperature, and hot-pressing time of the steel film of the hot-press machine as required: the pressure range is 360 tons, the temperature is 180°C, and the hot-pressing time is 20 seconds;

[0024] Step 3. Start the hot press to heat the steel film. When the temperature of the steel film reaches the set temperature, the table of the hot press drives the gypsum board and the foam paper to rise. When the gypsum board and the foam covering it When the adhesive paper sheet is close to the steel film at hi...

Embodiment 3

[0027] Such as figure 1 Shown is a kind of preparation technology of composite bubble gum paper sheet on the surface of paper-faced gypsum board, specifically comprises the following steps:

[0028] Step 1. Place the gypsum board on the table of the high-temperature and high-pressure heat press, select foam paper with specific colors and patterns according to the customer group, and then place the selected foam paper on the gypsum board;

[0029] Step 2. Set the pressure value, temperature, and hot-pressing time of the steel film of the hot-press machine as required: the pressure range is 432 tons, the temperature is 200°C, and the hot-pressing time is 15 seconds;

[0030] Step 3. Start the hot press to heat the steel film. When the temperature of the steel film reaches the set temperature, the table of the hot press drives the gypsum board and the foam paper to rise. When the gypsum board and the foam covering it When the adhesive paper sheet is close to the steel film at hi...

Abstract

The invention discloses a preparation process for compounding a glue impregnated paper sheet on the surface of a gypsum plaster board. The process specifically comprises the following steps of: placing a gypsum plaster board on a table board of a hot press, and then placing the glue impregnated paper sheet on the gypsum plaster board; setting the pressure value, temperature, hot pressing time andthe like of a hot press steel film as required; when the temperature of the steel film reaches a set temperature, raising the table top of the hot press to enable the glue impregnated paper sheet to make contact with the steel film to start hot pressing; and after hot pressing is completed, conducting natural cooling to obtain a finished product. The processed gypsum plaster board does not need tobe polished and brushed in the later period, is formed at a time in a factory, and is low in cost and free of dust pollution; the formed surface, due to the characteristics of the glue impregnated paper sheet, can be cleaned and wiped; after hot pressing, the outer layer surface of the glue impregnated paper sheet is hardened, textured and easy to clean.

Description

technical field [0001] The invention relates to the technical field of gypsum boards, in particular to a preparation process for compounding foam paper sheets on the surface of paper-faced gypsum boards. Background technique [0002] Gypsum boards are often used in the home improvement industry. After installation, the gypsum boards often need to be painted, polished and brushed on the surface for many times. Dust pollution is more harmful to the constructors, and it is easy to be stained and refurbished frequently. Contents of the invention [0003] The purpose of the present invention is to provide a preparation process for compounding foam paper sheets on the surface of gypsum boards, by using a unique hot pressing process to compound foam paper sheets on the surface of gypsum boards, eliminating the need for later polishing layers process, thereby solving the problems raised in the above-mentioned background technology. In order to achieve the above object, the prese...
