Problems solved by technology

[0003] In actual use, the local micropores of the resin mold may be blocked, poorly drained or damaged due to the entry of slurry
Since resin molds are mostly cast in one piece, the cost is relatively high. When a local problem occurs and cannot be used normally, it can only be scrapped as a whole. On the one hand, it causes a waste of resources, and on the other hand, it also increases the economy of ceramic production. cost
At present, there is no technology for regeneration and repair of resin molds

Embodiment Construction

[0027] The high-pressure resin mold to be repaired in the present invention is a mold used in the high-pressure grouting ceramic molding process. It is formed by integral casting of microporous resin, and the mold cannot be used normally due to micropore blockage, poor drainage or damage. For example, the thickness of the surface used for common high-pressure resin molds is 25-30mm, followed by a number of comb-shaped water passages, which correspond to the substrate water tanks installed below them.

[0028] Repair compound for repairing high-pressure resin molds, including the following components:

[0029] Distilled water 20%-28%, acrylic acid powder 33%-40%, dibenzoyl peroxide 0.3%-0.8%, glass micropowder 17%-23%, methyl methacrylate 15%-20%, surface emulsifier 0.1 %-0.5%.

[0030] Preferably, it consists of:

[0031] Distilled water 22%-25%, acrylic acid powder 35%-37%, dibenzoyl peroxide 0.5%-0.6%, glass micropowder 19%-21%, methyl methacrylate 17%-19%, surface emulsif...

Abstract

The invention discloses a repair material for a high-pressure resin mold. The repair material comprises 20%-28% of distilled water, 33%-40% of acrylic powder, 0.3%-0.8% of dibenzoyl peroxide, 17%-23% of glass powder, 15%-20% of methyl methacrylate and 0.1-0.5% of an emulsifier. The invention also discloses a process for regenerating a to-be-repaired high-pressure resin mold by using the repair material. The process comprises the following steps: after requiring a to-be-repaired place of the mold, casting the repair material at 15 and 20 DEG C and slowly curing the repair material at low temperature; and soaking the repaired mold in water with a temperature of 30 and 50 DEG C for 8-16 hours and cleaning the mold for subsequent usage. In the repaired place of the repaired high-pressure resin mold, bonding is smooth, cracking does not occur and uniform drainage is realized; the repaired high-pressure resin mold can be reused more than 2000 times; so recycling of the mold is realized, and ceramic production cost is reduced.

Description

technical field [0001] The invention relates to a mould, in particular to a repairing material for a high-pressure resin mold and a process for regenerating a high-pressure resin mold using the repairing material. Background technique [0002] At present, ceramic molding mostly uses high-pressure molding technology, especially in the field of ceramic sanitary ware. High-pressure molding process refers to that during the grouting process, a certain pressure is applied to the slurry filled into the mold to discharge water, so that the slurry is quickly dehydrated and hardened to form a green body, in which the micropores of the mold serve as the rapid discharge of water in the slurry aisle. There are criss-cross channels inside the resin mold, and the hole diameter is larger. Compared with the plaster mold, it is more suitable as a drainage channel under high pressure, and the resin mold has good compressive and flexural properties, high hardness, and good toughness, so it is...
