Embodiment 1
[0041] An epoxy resin based mineral casting consisting of:
[0042] Aggregate 86kg, binder 8kg, filler 5kg, reinforcing agent 1kg; the total amount of all components is 100kg.
[0043] The preparation method of above-mentioned epoxy resin-based mineral casting, concrete process is as follows:
[0044] (1) Preparation of adhesive:
[0045] S1, preparation of epoxy resin: heat E51 type epoxy resin and F51 type epoxy resin at 80°C to a constant temperature, then mix them evenly according to the ratio of mass ratio 8:2, and fill them for use;
[0046] S2, preparation of curing agent: mix isophorone diamine and polyether amine D230 evenly according to the mass ratio of 2:1, and fill the equipment for use;
[0047] (2) Preparation of aggregate particles:
[0048] The natural granite is crushed and sieved, divided into 6 grades according to particle diameter, and graded according to the following ratio:
[0049] 0.1-1mm: 11%; 1-2mm: 12%; 2-4mm: 14%; 4-8mm: 18%; 8-14mm: 20%; 14-25...
Embodiment 2
[0058] An epoxy resin based mineral casting consisting of:
[0059] Aggregate 85kg, binder 9kg, filler 5kg, reinforcing agent 1kg; the total amount of all components is 100kg.
[0060] The preparation method of above-mentioned epoxy resin-based mineral casting, concrete process is as follows:
[0061] (1) preparation of adhesive: same as embodiment 1;
[0062] (2) Preparation of aggregate particles:
[0063] The marble is crushed and sieved, divided into 6 grades according to particle diameter, and graded according to the following ratio:
[0064] 0.1-1mm: 10%; 1-2mm: 10%; 2-4mm: 15%; 4-8mm: 20%; 8-14mm: 20%; 14-25mm: 25%;
[0065] The marble is a waste material of a stone processing enterprise, and aggregates are obtained by mixing the graded particles;
[0066] Clean the aggregate, dry it with hot air at 200°C until the moisture content is less than 0.1%, then weigh the dried aggregate according to the formula and place it in the stirring device;
[0067] (3) After stir...
