Multifunctional chorine-free and benzene-free compound paint stripper and production method thereof

Abstract

The invention discloses a multifunctional chorine-free and benzene-free compound paint stripper and a production method thereof. The multifunctional chorine-free and benzene-free compound paint stripper is a composition, which is characterized in that: the composition comprises the following components in part by weight: 30 to 60 parts of main solvent, 5 to 30 parts of latent solvent, 5 to 30 parts of solubilizer, 2 to 15 parts of accelerant, 2 to 15 parts of activating agent, 1 to 6 parts of osmotic agent, 0.5 to 2.5 parts of inhibitor, 1 to 8 parts of sealant, and 0.1 to 0.6 parts of thickening agent. The production method comprises the following steps: adding the main solvent in a reaction kettle; adding the latent solvent, the activating agent and the accelerant to the main solvent dropwise with stirring; stirring the mixture until the mixture is dissolved completely; adding the thickening agent and stirring the mixture until the thickening agent is dissolved; adding the thickening agent to the mixture again and mixing with the solubilizer; and finally, adding the sealant and the inhibitor and stirring the mixture uniformly. The pain stripper in the invention avoids harm to a human body, environmental pollution and causticity, and has a large foaming area, a short paint stripping time, little dosage and high frequency when demoulding. The production method in the inventionis simple in process, less in device investment, rich in raw material resource and low in product cost.

Description

Technical field [0001] The invention belongs to the technical field of paint removers and provides a chlorine-free and benzene-free multifunctional composite paint remover and a production method thereof. Background technique [0002] Before repainting old furniture, home appliances or equipment parts, or protecting the surface of certain objects, such as roads and buildings, it is often necessary to strip the old paint film. The removal of the old paint film is based on different requirements, different substrates, and different coatings, so there will be different methods, such as: combustion method, laser paint removal method, mechanical or manual treatment and use of paint remover. The use of paint stripper has the advantages of good paint stripping effect, economy and convenience. [0003] At present, chemical paint removers used in industry usually contain more dichloromethane, phenol, volatile solvents and other harmful substances, resulting in high volatility and toxicity ...
