Abstract

The invention discloses interior wall latex paint, comprising odorless styrene-acrylic emulsion, water, paint, a filler, a film forming assistant and assistants. The invention adopts the odorless styrene-acrylic emulsion which is produced by the vapor desorption technology and has low content of residual monomers and low film forming temperature as the binding material and the fraction extracted from the vegetable oil as the film forming assistant, thus avoiding the organic volatile matters which are brought by the conventional film forming assistants and harmful to the human bodies and trulyachieving the aims of being healthy and environment-friendly and being harmless to the human bodies. The latex paint is suitable for decoration in the public places, especially decoration in the places where the personnel and equipment can not evacuate.

Description

technical field [0001] The invention relates to an interior wall latex paint, in particular to a low-odor, low-VOC healthy and environment-friendly paint, which belongs to the field of environment-friendly paint. Background technique [0002] With the rapid development of the paint industry, paint home decoration is becoming more and more common. However, the existing decorative coatings have high content of free monomers, free formaldehyde, and APEO. After decoration, coughs, sore throats, and unbearable pungent odors often occur, causing serious damage to the human respiratory tract. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an environment-friendly, low-odor interior wall coating to solve many deficiencies in existing interior wall decoration coatings. In formula design, in addition to selecting low-VOC, low-odor net In addition to flavored emulsion, the main invention is to extract fractions from vegeta...
