[0020] The mold for building material products of the present invention is composed of a surface layer of non-stick material, an adhesive layer and a hard base material.
[0021] Specific steps are as follows:
[0022] 1) Use an air pump to clean the surface of the master mold, then evenly brush the release agent and let it stand for 10 minutes;
[0023] 2) Use a spatula to evenly spread the silicone surface layer on the surface of the master mold; after vacuum treatment, place two 25 angle irons in the length and width directions of the mold, and let it stand for 30 minutes;
[0024] 3) After the silicone surface layer is gelled, use a spatula to lay a silicone adhesive layer with a thickness of 2mm and vulcanize at room temperature for 10 minutes; lay a layer of gauze and let it stand for 60 minutes to wait for condensation;
[0025] 4) Lay the epoxy resin adhesive layer, that is, evenly lay a layer of epoxy resin gel coat on the gauze, then lay the glass fiber mesh cloth i...

Abstract
The invention discloses a die for building materials products and a preparation method thereof. The die provided by the invention contains a preformed female die and is prepared by the following steps of: cleaning the female die by an air pump, coating a mold releasing agent on the surface of the female die, uniformly laying a silica gel surface layer on the surface of the female die coated with the mold releasing agent to form a nonstick material surface layer, placing a bar of angle iron at each long side of the die; successively laying a silica gel bonding coat and a layer of gauze on the silica gel surface layer after its gelation, laying an epoxy resin bonding layer and a layer of glass fiber grid cloth after coagulation of the silica gel bonding layer to form a bonding layer; laying an insulation plate and flat iron on the bonding layer, pressing tightly by using a steel plate and simultaneously installing seal section bars at the four corners of the die; laying epoxy resin mortar on the surface of the insulation plate to form a light filling layer; laying a layer of glass fiber biaxial cloth on the light filling layer, and laying an epoxy adhesive coat on the glass fiber biaxial cloth to form a hard base material. The die provided by the invention has a simple structure, is easy to demould, and can be used to effectively guarantee the quality of moulded products. In the meantime, the preparation method provided by the invention is convenient to operate, requires low cost, and is easy to maintain.
Description
technical field [0001] The invention relates to a mold and a preparation method thereof, in particular to a mold for building material products and a preparation method thereof. Background technique [0002] At present, the molds used in building materials are basically glass fiber reinforced plastic and silicone molds. The production of glass fiber reinforced plastic molds belongs to the traditional craft, which has the advantages of fast forming and high hardness. Chinese patent CN 101579899 A and Chinese patent CN 201320814 Y respectively describe two kinds of FRP mold manufacturing processes. However, the FRP mold prepared by the traditional process has the following disadvantages: 1) The release agent needs to be brushed before each use, which increases the manufacturing process and cost, and the release agent will pollute the surface of the building material product and affect the quality of the building material product; 2) It is very easy to cause the product to be...
