Problems solved by technology

[0003] There are many kinds of anti-corrosion primers, but epoxy resin is the most widely used variety in the market due to its unique properties. This type of anti-corrosion primer has the advantages of good acid resistance, alkali resistance, low shrinkage, and strong corrosion resistance. , but the weather resistance is relatively weak, so everyone has done a lot of work on the modified epoxy resin anti-corrosion primer, and there are already mature products, such as the most widely used epoxy zinc-rich paint on the market, but there are still some functions. It needs to be sand blasted, and the amount of metal elements is large, etc. The market lacks some energy-saving and high-efficiency anti-corrosion products.

Embodiment 1

[0026] The formula of Jiubao new anti-corrosion primer is shown in Table 1.

[0027] Table 1

[0028]

[0029]

[0030] According to the formula in the above table, prepare component A and component B separately and then mix them evenly. The dosage of component B is 10wt% of that of component A, then mix evenly and apply in the product.

[0031] The following table is the salt spray performance comparison of embodiment 1 and epoxy zinc-rich primer:

[0032] Table 2 Example 1 and epoxy zinc-rich primer salt spray performance comparison

[0033]

[0034] Epoxy zinc-rich primer is used on the sandblasted steel plate, the average film thickness is about 80 μm, and the theoretical dosage is 380g, while Example 1 is used on the artificially derusted steel plate, the theoretical dosage is 238g, and the dry film thickness can also reach 80 μm.

Embodiment 2

[0036] The formula of Jiubao new anti-corrosion primer is shown in Table 3.

[0037] table 3

[0038]

[0039]

[0040] According to the formula in the above table, prepare component A and component B separately and then mix them uniformly. The dosage of component B is 5wt% of component A, then mix and evenly coat the product.

[0041] The following table is the salt spray performance comparison of embodiment 2 and epoxy zinc-rich primer:

[0042] Table 4 Example 2 and epoxy zinc-rich primer salt spray performance comparison

[0043]

[0044] Epoxy zinc-rich primer is used on the steel plate after sandblasting, the average film thickness is about 80 μm, and the theoretical dosage is 380g, while Example 2 is used on the artificially derusted steel plate, the theoretical dosage is 230g, and the dry film thickness can also reach 80 μm.

Embodiment 3

[0046] The formula of Jiubao new anti-corrosion primer is shown in Table 5.

[0047] table 5

[0048]

[0049] According to the formula in the above table, prepare component A and component B separately and then mix them evenly. The dosage of component B is 15wt% of that of component A, then mix evenly and apply it in the product.

[0050] The following table is the salt spray performance comparison of embodiment 3 and epoxy zinc-rich primer:

[0051] Table 6 Example 3 and epoxy zinc-rich primer salt spray performance comparison

[0052]

[0053] Epoxy zinc-rich primer is used on the sandblasted steel plate, the average film thickness is about 80 μm, and the theoretical dosage is 380g, while Example 3 is used on the artificially derusted steel plate, the theoretical dosage is 234g, and the dry film thickness can also reach 80 μm.

Abstract

The invention relates to a durable fresh-maintained preservative primer. Raw materials of the primer comprises a component A and a component B, wherein the consumption of the component B is 5-15 percent by weight that of the component A; the component A comprises the following components in percentage by weight: 20-50 percent of epoxy resin, 10-30 percent of phosphate, 1-10 percent of additive, 5-20 percent of diluting agent and 15-35 percent of solvent; and the component B comprises the following components in percentage by weight: 50-80 percent of curing agent and 20-50 percent of solvent. Compared with the prior art, the durable fresh-maintained preservative primer disclosed by the invention has the advantages of favorable adhesive force, strong laminated coating property, tough and tensile paint film, impact resistance, convenience in construction, long preservative effect cycle, favorable construction matching property and particularly excellent salt spray resistance.

Description

technical field [0001] The invention relates to a primer, in particular to a Jiubaoxin anticorrosion primer. Background technique [0002] Buildings such as reinforced concrete structures, steel structures, and steel-concrete hybrid structures have grown rapidly due to their advantages such as fast speed, low construction pollution, light weight, easy modeling, short construction period, and good seismic performance; at the same time, with the steel structure industry The rapid development of the anticorrosion industry, and the corresponding steel structure anticorrosion primer has become the development direction of the anticorrosion industry. [0003] There are many kinds of anti-corrosion primers, but epoxy resin is the most widely used variety in the market due to its unique properties. This type of anti-corrosion primer has the advantages of good acid resistance, alkali resistance, low shrinkage, and strong corrosion resistance. , but the weather resistance is relative...
