Problems solved by technology

For example, the existing domestic non-anti-static plexiglass substrates (domestic substrates for short) are used to produce anti-static plexiglass panels. Although domestic substrates are very cheap, it is difficult to combine them with anti-static coatings. The layer is very easy to peel off, the anti-static effect is poor, and it has no market value
However, the price of imported substrates is high (37 yuan per kilogram), and additional tariffs need to be paid, resulting in high costs for enterprises to obtain imported substrates
Therefore, existing antistatic plexiglass plate has the defect that acquisition cost is high

Embodiment 1

[0018] Embodiment 1 (best embodiment). The production method of antistatic plexiglass board substrate, comprises the following steps,

[0019] Polymerization kettle step, in every ton of MMA raw material (liquid state), add the initiator of 12g low-temperature type, in polymerization kettle, be heated to 95 ℃, keep warm, heat preservation time is determined according to the purity of MMA raw material, when the purity of MMA raw material is greater than 99.9%, The MMA raw material is a commercially available new material, the holding time is 42min, and when the purity of the MMA raw material is 95-97%, the MMA raw material is a commercially available reclaimed material, and the holding time is 70min. After the heat preservation, it is naturally cooled to normal temperature to obtain product A ;

[0020] Mixing step, add 12% initiator and 10Kg plasticizer in every ton of A product, mix evenly, get B product;

[0021] The vacuum filtration step is used to eliminate the air bubb...

Embodiment 2

[0025] Example 2. Different from Example 1, in the polymerization kettle step, 10 g of the initiator is heated to 110° C. in the polymerization kettle. When the purity of the MMA raw material is greater than 99.9%, the holding time is 40 minutes, and the purity of the MMA raw material is 95- When 97%, the holding time is 60 minutes.

[0026] In the mixing step, the initiator is 10g, and the plasticizer is 9Kg.

[0027] In the vacuum filtration step, the relative vacuum is a negative pressure of 0.09 MPa, the vacuum time is 30 min, and the filter material is a 150-mesh filter cloth, which is filtered five times.

[0028] In the universal fixation step, the product D is heated to 95°C.

Embodiment 3

[0029] Example 3. Different from Example 1, in the step of the polymerization kettle, the initiator 15g is heated to 80°C in the polymerization kettle, and when the purity of the MMA raw material is greater than 99.9%, the holding time is 45min, and the purity of the MMA raw material is 95- When 97%, the holding time is 80 minutes.

[0030] In the mixing step, the initiator is 13g, and the plasticizer is 11Kg.

[0031] In the vacuum filtration step, the relative vacuum degree is a negative pressure of 0.07MPa, the vacuum time is 45min, and the filter material is a 300-mesh filter cloth, and is filtered three times.

[0032] In the universal fixation step, the product D is heated to 100°C.

[0033] Embodiment 1 is an improvement made on the production process of domestic substrates. The obtained substrates can be firmly combined with antistatic coatings, and antistatic plexiglass panels can be well produced with low cost. The main points of improvement are: first, in the mix...

Abstract

The invention discloses a production method of an anti-static organic glass plate substrate, which comprises the following steps: a polymerization kettle step: adding 10-15g of initiator into each ton of MMA raw material, heating to 80-110 DEG C in the polymerization kettle, preserving heat, determining the heat preservation time according to the purity of the MMA raw material, and naturally cooling to normal temperature after heat preservation to obtain a product A; a material mixing step: adding 10-13g of an initiator and 9-11Kg of a plasticizer into each ton of the product A, and uniformly mixing to obtain a product B; a vacuum filtration step: performing vacuum filtration on the product B to obtain a product C; a mold filling step: filling the product C into a mold for forming the substrate, and then putting the mold into a warm water pool to solidify the product C to obtain a product D; a ten-thousand-force fixing step: heating the product D to 105-115 DEG C, and preserving heat to obtain a product E; and a mold removal and maintenance step: removing the mold on the product E to obtain a finished product of the substrate.

Description

technical field [0001] The invention belongs to the field of antistatic organic glass plate substrates, in particular to a production method of antistatic organic glass plate substrates. Background technique [0002] Anti-static plexiglass panels are widely used in industry and are made by spraying anti-static coatings on plexiglass substrates. At present, there is only one kind of antistatic coating suitable for spraying antistatic plexiglass panels, and it can only be imported from abroad. The model of this antistatic coating is American ACL-2005 liquid. At present, the substrate suitable for making anti-static plexiglass panels (referred to as imported substrate) can only be imported from abroad. The production process of imported substrates is still kept secret, and the domestic production capacity is not yet available. For example, the existing domestic non-anti-static plexiglass substrates (domestic substrates for short) are used to produce anti-static plexiglass pane...
