Problems solved by technology

[0002] At present, the current situation of the domestic rust removal industry, most of the spraying materials used by the operating units are directly using abrasives or copper slag, river sand, etc., to derust metal objects, the abrasive waste used is serious, and the dust in the operation is extremely large. Especially when working in the field, the smoke and dust are billowing, causing great pollution to the environment, air, and river water resources. Moreover, the abrasive particle size used is small, which makes it difficult to realize field recycling, and brings secondary pollution to the environment. The rigidity of the abrasive Strong, strong rebound force on the working surface during spraying, easy to hurt the construction personnel, while spraying operations, most of the work types in the work area must be shut down, and other work can only be followed after rust removal, which cannot be done Derusting at the same time as other types of work, thus wasting a lot of precious time, human resources and a lot of money

[0048] Next, weigh the raw materials according to the proportions in Table 1, and prepare according to the steps of the following preparation method. The difference is that the added raw material proportions are different, and the products are prepared. See Table 1-3 for details:

[0049] Wherein the polyether polyol described in Table 1-3 is the polyether polyol produced by Wanhua Chemical Group Co., Ltd. The abrasive is a mixture of glass beads and fine sand mixed with glass sand and fine sand at a weight ratio of 1:4. The average particle size of the abrasive is 50-200um; the coupling agent is γ-aminopropyltriethoxysilane (KH650), and the tension agent is the tension agent produced by Taian Quanxin Chemical Technology Co., Ltd., which is the model xq-124 agent. The antistatic agent is sodium alkyl sulfonate, the stabilizer is calcium / zinc composite stabilizer, the catalyst is stannous octoate T-9, the plasticizer is di-n-octyl phthalate (DNOP), and the fungicide is phenol ...

Abstract

The present invention discloses a polyurethane environmental-protection spraying material and a preparation method thereof, wherein the polyurethane environmental-protection spraying material is prepared from the following components by weight: 50-85 parts of polyether polyol, 10-45 parts of diphenylmethane, 40-80 parts of isocyanate, 1-10 parts of ethylene glycol, 1-6 parts of purified water, 50-120 parts of an abrasive material, 1-5 parts of a coupling agent, 2-10 parts of a pulling force agent, 1-5 parts of an antistatic agent, 1-9 parts of a stabilizer, 0.05-2 parts of a catalyst, 1-3 parts of a plasticizer, 1-3 parts of a anti-mildew agent, and 0.02-1 part of a pigment. According to the present invention, the polyurethane environmental-protection spraying material prepared by using the raw material ratio of the technical scheme has excellent elongation at break, excellent tear strength, excellent resilience, and other excellent performances.

Description

technical field [0001] The invention relates to the field of derusting environmental protection materials, more specifically relates to a polyurethane environmental protection spray material and a preparation method thereof, the material is mainly used in the surface treatment of metal structural parts, metal derusting operations in the waste water treatment industry, and has strong Excellent rust removal, decontamination, removal of new and old paint polishing ability, and can be recycled repeatedly, is a more practical environmental protection spraying material. Background technique [0002] At present, the current situation of the domestic rust removal industry, most of the spraying materials used by the operating units are directly using abrasives or copper slag, river sand, etc., to derust metal objects, the abrasive waste used is serious, and the dust in the operation is extremely large. Especially when working in the field, the smoke and dust are billowing, causing gr...
