Production method and raw material formula of strongly-effective anticracking glue

Abstract

The invention relates to a production method and a raw material formula of strongly-effective anticracking glue which comprises a main agent and a curing agent, the main agent comprises the following raw materials: 40%-50% of epoxy resin, 5%-15% of a diluent, 5%-25% of bentonite and 30%-60% of Shuangfei powder, the raw materials are mixed according to the proportion and then are made into paste for standby use through mixing; the curing agent comprises the following raw materials: 40%-50% of fatty amine, 5%-15% of a diluent, 5%-25% of bentonite and 30%-60% of Shuangfei powder, the raw materials are mixed according to the proportion and then are made into paste for standby use through mixing; the standby paste main agent and the standby paste curing agent are evenly mixed in the weight ratio of 2 to 1, or evenly mixed in the weight ratio of 1 to 1 or a proper weight ratio, and then the strongly-effective anticracking glue is coated or scraped at seam crossing; the strongly-effective anticracking glue product eliminates the need of other anticracking handling after use, the working procedure can be completed in one step, and the construction is convenient, time saving, labor saving and material saving and can be completed by scraping once.

Description

technical field [0001] The present invention is characterized by the strong anti-cracking effect produced by it, such as the production method of the glue filled with putty, especially belongs to the field of the production method and formulation of anti-cracking glue. Background technique [0002] In the existing technology, white latex or other adhesives are generally used to paste kraft paper or grid tape and linen etc. for anti-cracking of decoration joints. Some also use epoxy resin and curing agent to add powder at the construction site, stir it into a paste putty and apply it to the joints to paste kraft paper, mesh belt and linen products. Its disadvantages: because it is too hard and easy to crack, it is necessary to stick linen to prevent cracking. There is also Xiamen Dongshun Coatings Co., Ltd. patent application number: 201110114895.8, patent name: two-component joint paste, patent content features: A component is the main agent: epoxy resin 32%-36%, thinner 0....

Problems solved by technology

Its disadvantages: because it is too hard and easy to crack, it is necessary to stick linen to prevent cracking

Therefore, the patented product applied by Xiamen Dongshun Paint Co., Ltd. is actually a product that cannot be implemented, and it is also an invalid patented product

[0004] If bentonite is added to the above-mentioned patent formula of Xiamen Dongshun Coatings Co., Ltd. to produce a joint paste product, then this product also has the following three disadvantages: its disadvantage 1: due to the addition of polypropylene fiber, it is more difficult to apply when applying and scraping. It is laborious, especially when the temperature is low in winter, the product will become very thick and difficult to apply; its disadvantage 2: due to the addition of quartz sand or other sand, the gap cannot be filled in the relatively small connection gap during coating and scraping construction , resulting in hollowing and cracking; its disadvantage 3: construction in winter when the temperature is as low as 5 degrees, and the drying time takes about 72 hours, which causes a lot of inconvenience and affects other processes that cannot be carried out normally

The above-mentioned patented products applied by Xiamen Dongshun Coatings Co., Ltd. not only have complex production and construction processes, poor anti-cracking effect, poor construction performance, uncontrollable product performance and drying time, and high construction costs, but are actually impossible to implement at all. It is an invalid patented product without the basic function of seam crack resistance

The patented product applied by Xiamen Dongshun Coatings Co., Ltd. has no creativity. More importantly, its patented technology product is actually unable to form an effective joint paste product, and it is also a product that cannot be implemented.
