preparation example Construction

[0062] The preparation of the substrate layer is as follows:

[0063] Place the quantified kraft paper in thermosetting phenolic resin, impregnate at a speed of 27-45m / min, and dry at 130-150°C after impregnation, with a machine speed of 27-45m / min; After completion, a single-layer kraft paper layer can be obtained. The sizing amount of the kraft paper is 45-60% (the sizing amount refers to: the sizing amount of the resin impregnated on the kraft paper accounts for 45-60% of the pure surface paper mass before sizing), and the volatile matter when dry It is 7.5-9.5% (the volatile content refers to the percentage of moisture and volatile small molecular substances contained in the impregnated kraft paper in the mass of the impregnated kraft paper;).

[0064] In the actual use process, the number of kraft paper sheets is determined according to the actual use situation, and multiple sheets of kraft paper are combined to obtain the substrate layer.

Embodiment 1

[0108] A corrosion-resistant and anti-static decorative table top, such as figure 1 , image 3 As shown, the countertop includes a substrate layer 1, an antistatic layer 2, an adhesive layer 3 and a first corrosion-resistant and antistatic decorative layer 4 arranged sequentially on the upper surface of the substrate layer 1 from inside to outside; An antistatic layer 2, an adhesive layer 3 and a second corrosion-resistant and antistatic decorative layer 5 on the lower surface of the substrate layer 1;

[0109] The substrate layer 1 is obtained by stacking and bonding multiple layers of kraft paper impregnated with thermosetting phenolic resin. Single-layer kraft paper is 100g / m 2 , the thickness of kraft paper impregnated with resin and hot-pressed is 0.1mm;

[0110] Usually the required thickness of the substrate layer is 10-14mm.

[0111] The antistatic layer 2 is a carbon crystal antistatic layer, and the carbon crystal antistatic layer is 100~120g / m 2 carbon crystal ...

Embodiment 2

[0121] A method for preparing a corrosion-resistant and antistatic decorative table top, the method comprising the following steps:

[0122] (1) Preparation of corrosion-resistant and antistatic decorative layer:

[0123] According to the required ratio, add the measured polyurethane acrylate resin, diluent, antistatic agent, photoinitiator, thermosetting agent, and mold release agent into the stirring tank in proportion, and heat up from room temperature to 40-50 °C in the stirring tank. ℃, and stirred at this temperature for 20 to 30 minutes;

[0124] Then, the roll-shaped decorative paper is coated with the stirred resin mixture on its upper surface by the coating roller of the horizontal coating machine; The speed of the machine is 10-15m / min; after solidification is completed, it is cooled to room temperature by a water-cooled roller, and then cut into the required length;

[0125] Among them, the coating amount of resin is 120~170g / m 2 The thickness of the coating lay...

Abstract

The invention discloses a corrosion resistant antistatic decorative deck plate and a preparation method thereof. The deck plate comprises a substrate layer, and following layers, which are symmetrically arranged on the upper and lower surfaces of the substrate layer from inner to outer in sequence: antistatic layers, bonding layers, and corrosion resistant antistatic decorative layers. The deck plate is moulded at a time at a high temperature under a high pressure. A polyurethane acrylic resin layer, which contains a photo curing and thermal curing dual curing system having an ethoxylated amine antistatic agent, and a decorative paper layer are combined to prepare a surface decorative material; carbon crystal paper is used as the antistatic layers; under the action of other layers, the decorative deck plate with a prominent antistatic performance is obtained; two surfaces of the decorative deck plate are decorated, the structure is symmetrical; and the surface resistance is not more than 107 omega. The decorative deck plate has a strong antistatic property, is light, has a strong protection performance, can be made into multiple kinds of experiment table surfaces and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of antistatic decorative boards. In particular, it relates to a corrosion-resistant and antistatic decorative table top and a preparation method thereof. Especially suitable for decorative table tops for experiments. Background technique [0002] The test bench is one of the most important equipment in the laboratory. All kinds of chemical or physical experiments of the experimenters need to be completed on the test bench. Every scientific and technological pre-experiment is inseparable from a large number of experimental processes. Therefore, under the conditions of continuous and rapid development of science and technology in all aspects, there is a great demand for test benches and their panels, and in the course of experiments, the panels of test benches must have excellent properties such as corrosion resistance and fire prevention. [0003] At present, the laboratory countertop materials mainly inclu...
