Problems solved by technology

[0004] 2. The production of oil tanks consumes a lot of energy
For example: a 50 cubic meter horizontal oil tank needs to consume nearly 9 tons of steel; and the production of steel itself is high energy consumption and high pollution
[0005] 3. Quality control is difficult
On-site molding and installation are highly dependent on objective factors such as climate and environment, and require high construction technology and personnel skills, making it difficult to achieve ideal construction results during wartime production
[0006] 4. Difficulty in hoisting and transportation
It is almost difficult to transport and hoist above 50 cubic meters, so it can only be made on site
[0007] To sum up, traditional steel oil tanks consume a lot of energy, have poor corrosion resistance, and have a long manufacturing cycle, which is not conducive to the long-term storage of oil in peacetime, and it is also difficult to meet the needs of rapid turnover, sending and receiving, and protection of oil in wartime
[0008] These technical problems have existed for a long time, but so far there is no perfect and feasible technical solution to solve these technical problems

preparation example Construction

[0043] The preparation method of aforementioned plastics, the step comprises:

[0044] a. Nano-silica is coated with a silane coupling agent as organic silicon;

[0045]b. Add raw materials other than reinforcing fibers to the unsaturated polyester, and mix evenly with a mixer to obtain unsaturated polyester mass molding compound resin paste;

[0046] c. Soak the prepared resin paste in the kneader to reinforce the fiber, and add the fiber within 5 minutes. After kneading for 10-20 minutes, let it fully mix;

[0047] d. Extrude the dough soaked with reinforcing fibers with an extruder, seal and pack it with a polyethylene film, and place it at room temperature for 24 hours to obtain an unsaturated polyester fiber reinforced dough molding compound.

[0048] It is those skilled in the art that can be implemented according to the prior art as for further manufacturing component group with plastics. The prefabricated parts are then connected to form the oil tank.

Abstract

The invention relates to a reinforced plastic and an oil tank, and aims to provide an anti-corrosion, oil-resistant and flame-retardant oil tank which has reliable physical property and is made of reinforced plastic. The technical point is as below: the bulk molding compound comprises the following components in parts by weight: 34-47 parts of unsaturated polyester, 0.3-0.4 part of cobalt naphthenate, 0.3-0.35 part of methyl ethyl ketone peroxide, 45-47 parts of calcium carbonate, 0.1-0.3 part of antistatic agent, 0.1-0.15 parts of antioxygen, 0.1-0.15 part of pentabromo phenol, 0.1-0.3 part of microencapsulation tri-(2,3-dibromopropyl) isocyanuric acid ester, 0.1-0.2 part of melamine, 0.08-0.1 part of nano silica, a proper amount of silane coupling agent and 28-31 parts of reinforced fiber. The plastic can endure the temperature of 360 DEG C and 64 DEG C below zero, has constant physical property and has the advantages of high toughness and strength. The impact resistance of the unsaturated polyester fiber-reinforced bulk molding compounds is effectively improved. The reinforced plastic is anti-corrosion, anti-aging, oil resistant and flame retardant, and is suitable for manufacturing oil tanks.

Description

technical field [0001] The present invention relates to reinforced plastics, and also relates to oil tanks. Background technique [0002] In the prior art, medium and small-sized oil tanks are mainly made of steel horizontal structures. Such tanks have many disadvantages: [0003] 1. Easy to corrode. Corrosion is particularly serious in soils under strong acid and alkali environments. The designed service life of domestic oil tanks is generally 15 years. Relevant documents disclose that oil tank corrosion leakage has become an important source of environmental pollution in EU countries. For example, one-third of gas stations in the UK have caused serious pollution to soil and groundwater. [0004] 2. Oil tank production consumes a lot of energy. During the production and installation of raw materials and products, traditional energy sources such as water, electricity, coal and fuel oil are consumed a lot. For example: a 50 cubic meter horizontal oil tank needs to consu...
