Embodiment 1
[0022] Mix 2 parts of the crushed granite stone powder waste in a mixer, add 1 part of unsaturated resin, 0.015 part of methyl ethyl ketone peroxide, and 0.01 part of red material at the same time, and continue stirring for 2 hours until uniform. The mixture is poured into a plaster mold in the shape of a lounge chair, and then formed after vacuum vibration with a vibrating screen for 30 minutes. After the mixture in the plaster mold is solidified (curing time is 4 hours), the demoulding process is performed. (wherein the number of parts refers to parts by weight)
[0023] The obtained product is detected, and the data are as follows:
[0024] 1. Resistance to temperature difference -30°C-50°C;
[0025] 2. The warpage at the plane is ≤3mm;
[0026] 3. The shrinkage deformation rate of the product is ≤2mm / m2;
[0027] 4. Anti-bending and anti-deformation strength: 75 kg, no deformation when heavy objects act on the midpoint;
[0028] 5. The thickness of the product is 4-6m...
Embodiment 2
[0030] Prescription is as follows (floating 5%, wherein parts refer to parts by weight):
[0031] 1 part of unsaturated resin;
[0032] Granite powder 2.1 parts;
[0033] 0.01575 parts of methyl ethyl ketone peroxide;
[0034] 0.0105 copies of red material;
[0035] Prepare the outdoor FRP table according to the method of Example 1.
Embodiment 3
[0037] Prescription is as follows (floating 5%, wherein parts refer to parts by weight):
[0038] 1 part of unsaturated resin;
[0039] Granite powder 1.9 parts;
[0040] 0.01425 parts of methyl ethyl ketone peroxide;
[0041] 0.0095 copies of red material;
[0042] According to the method of Example 1, outdoor FRP railings were prepared.

Abstract
The invention relates to outdoor glass fiber reinforced plastic furniture which is made of wastes of granite. The formula comprises a resin, granite powder, a curing agent, an accelerant, etc. The granite powder is stirred with the resin and then added with the accelerant and the curing agent, etc., the mixed materials are poured into a gypsum die and vibrated for forming by a vibration sieve in vacuum; after curing, the die is removed and the product is obtained. The product of the invention can be used as outdoor dark furniture and is firm and durable, weather resistant and rainwater corrosion resistant; the technology is simple and the cost is low, thus having good popularization value.
Description
[technical field] [0001] The present invention relates to a public facility. More specifically, the present invention relates to the manufacture of outdoor furniture from granite stone waste. [Background technique] [0002] With the prosperity and development of the economy and the improvement of living standards, people spend more and more time outdoors. Correspondingly, people's demand for outdoor activity facilities is also increasing, such as lounge chairs, sofas in rest places in parks and tourist areas, seats in outdoor sports fields, and the like. At present, these outdoor furniture are basically made of wood or cement concrete. Wooden materials require a large amount of wood, which is not conducive to environmental protection, and is also not resistant to corrosion; while cement concrete materials are expensive, difficult to shape, and monotonous in appearance. In view of the above-mentioned defects of the prior art, it is necessary to develop new materials to pre...
