[0003] However, dibutyl phthalate is very harmful to the environment and human health, and commercially available industrial grade benzoyl peroxide contains 20%-30% water for the safety of transportation and storage. The marble glue curing agent cannot be completely removed during the production process and is brought into the curing agent. When mixed with dibutyl phthalate, it is easy to cause phase separation of the curing agent, oil separation, water separation, etc., which is difficult form a stable state

Embodiment 1
[0034] This embodiment provides an environmentally friendly and stable marble glue curing agent, whose raw materials are composed of the following components by weight: 100 parts of benzoyl peroxide, 50 parts of acetyl tributyl citrate, 8 parts of dibutyl carbonate, 1.5 parts of 2-ethylhexyl acrylate-butyl methacrylate copolymer, 1.5 parts of polynorbornene resin, 0.75 parts of sodium starch xanthate-sodium acrylate graft copolymer, viscose fiber-acrylic acid graft copolymer 0.75 parts, 3 parts of zinc stearate and 3 parts of barium stearate.
[0035] This embodiment also provides the preparation method of the above-mentioned marble glue curing agent, which is as follows: first, add acetyl tributyl citrate, dibutyl carbonate and benzoyl peroxide to the kneading kettle and stir for 20 minutes at a speed of 400 r / min After the benzoyl peroxide is completely swollen, add the above-mentioned water absorbing agent, oil absorbing agent and anti-sedimentation agent to the kneading ke...

The invention provides an environment-friendly and stable marble glue curing agent and a preparation method thereof. The raw materials of the curing agent include, in parts by weight, 100 parts of benzoyl peroxide, 45-70 parts of an environment-friendly solvent, and 1-70 parts of an oil-absorbing agent. 5 parts and 0.5-2 parts of water absorbing agent; the environment-friendly solvent is composed of environment-friendly plasticizer and dibutyl carbonate in mass ratio (4-12):1. The environmentally friendly and stable marble glue curing agent provided by the present invention effectively replaces dibutyl phthalate by using an environmentally friendly plasticizer and dibutyl carbonate in a specific mass ratio, making the curing agent safer and more environmentally friendly At the same time, a certain proportion of oil absorbent and water absorbent is added to make the curing agent uniform and stable during the storage period, anti-attenuation, so as not to affect the use of the curing agent.
Description
technical field [0001] The invention relates to the field of stone bonding glue, in particular to an environment-friendly and stable marble glue curing agent and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of construction adhesives, marble glue has gradually become the leading product in the field of stone chemical industry. Marble glue has excellent performance, mainly reflected in hardness, toughness, fast curing, polishing, weather resistance, corrosion resistance and so on. The marble glue is mainly divided into two components, A and B. The A component is a colloid made of unsaturated polyester resin as the main resin, and the B component is a curing agent that causes the A component colloid to solidify. Most glue curing agents are pastes formed by dissolving the initiator benzoyl peroxide in dibutyl phthalate. [0003] However, dibutyl phthalate is very harmful to the environment and human health, and commerc...
