Embodiment 1

[0037] Preparation of metal primer:

[0038] 1) Add 150g of general-purpose neoprene rubber CR2321 (Changshou Chemical Industry) into the open mill, the roll distance is 4-5mm, add 1.5g of anti-aging agent BHT (Anhui Haihua Technology) after wrapping the rolls, and make a triangle after the material is eaten. Knead for 2 minutes, then adjust the roller distance to 1mm to produce a film to obtain a film;

[0039] 2) Take 800g of industrial toluene (Qingdao Jinpeng Chemical Industry Co., Ltd.) and pour it into a double-layer stainless steel closed reaction kettle with agitator, cut the film obtained in 1) into 30mm*30mm rubber blocks and add it to the reaction kettle, and the stirring speed is 600r / min, stir until the glue block dissolves evenly;

[0040] 3) Pour 3200g of industrial toluene into the reactor, add 1500g of chlorinated rubber CR20 (Dongxin Chemical) and 200g of light magnesium oxide (purity 99.5%) (Yantai Aifer Chemical), and stir for 16 hours. The temperature i...

Abstract

The invention relates to a room-temperature curing efficient adhesive and a preparation method thereof. The room-temperature curing efficient adhesive is composed of a metal primer and a chloroprene rubber adhesive, wherein a base formula of the metal primer comprises the following raw materials by weight: 1200-1500g of chlorinated rubber CR20, 100-200g of general chloroprene rubber CR2321, 1-3g of an anti-aging agent BHT, 200-300g of light magnesium oxide and 3,000-4,000g of industrial methylbenzene; and the chloroprene rubber adhesive comprises the following raw materials by weight: 50-70g of chloroprene rubber A-90, 30-50g of chloroprene rubber M-40, 1-3g of an anti-aging agent WSL, 0.1-0.6g of a red iron oxide pigment, 10-30g of chlorinated rubber R20, 10-50g of fumed silica, 6-8g of light magnesium oxide, 10-40g of terpene-phenolic resin, and 500-800g of a mixed solvent which is composed of methylbenzene and butanone according to the mass ratio of 3 to 2. The room-temperature curing efficient adhesive provided by the invention is high in adhesive strength, stable in quality and good in heat resistance, has good adaptability on metal materials and non-metal materials, and is suitable for large-scale bonding work.

Description

technical field [0001] The invention relates to a high-efficiency adhesive cured at room temperature and a preparation method thereof, belonging to the field of chemistry. Background technique [0002] Many chemical, mining and other equipment are subjected to strong chemical corrosion and solid particle wear during use, which greatly affects the service life, equipment maintenance costs are high, and normal production activities are affected; while rubber has a recognized Good anti-corrosion and wear-resistant effects have been widely used in these fields. It is the most common practice to use a metal skeleton to line a layer of rubber to resist corrosion and wear, and the effect is relatively ideal. For some metal parts with small specifications but complex structures, a layer of rubber can be lined by hot vulcanization by opening molds; but for some large-scale equipment (such as tanks, tanks), it is unrealistic to open molds, and The cost of large-scale flat vulcanizing...
