Description
Technical field
The present invention relates to paint fields, and in particular, to a kind of exploitation and application of New-type latex paint protective system.
Background technique
In coating process, in order to improve the workability and paint film property of coating, added auxiliary agent often contains micro- life
Nutrients necessary to object, is bacterium, and the microorganisms such as yeast and mold improve good growing environment.Therefore, aqueous
In the storage process of coating, usually because the breeding of bacterium, destroys properties of product, quality decline leads to coating occur
Phenomena such as surface discolouration, viscosity decline, pH value change, pigment precipitating, lotion flocculation, demulsification, generate peculiar smell or even surface mildew.
The discarded of coating is ultimately caused, is caused damages to user and the producer.Therefore, when producing and storing coating, it is necessary to add
Certain antibacterial, preservative inhibit and prevent the existence of microorganism, to guarantee the quality of product.
Currently, antibiotic antiseptic is that parabens, different plug oxazoline ketone etc. are efficient in common tank in domestic rustproof lacquer
Antibacterial agent.However these antibacterial agents still generate certain harm to human body, environment, relevant report both domestic and external is also increasingly
It is more, increasingly limited its dosage.On December 23rd, 2014, EU Committee has issued No.1103/2014 and No.1104/2014
Two regulation summaries, and come into force on April 16th, 2015.Regulation content includes, in conventional cosmetic, P-hydroxybenzoic acid third
The maximum of ester and butyl p-hydroxybenzoate is substantially reduced using concentration.And methylisothiazolinone (MIT) and the different thiophene of methyl chloride
Oxazoline ketone (CMIT) will be forbidden in the leave product for body lotion etc since on July 16th, 2015, and liquidate
It washes type product and is then reduced to 0.0015% or less using limitation.
Therefore, it finds antibiotic antiseptic in a kind of novel, safe and efficient latex paint can and becomes nowadays coating industry and compel
In the research direction of the eyebrows and eyelashes, replaces original different plug oxazoline ketone protective system, also comply with the technology of current green chemistry
It is required that.

----indicate without.
The antibiotic property of Gemini quaternary ammonium salt preservative is tested
It is main to use common CTFA Bacterial challenges experimental test procedures in the world.The method of the test is specific as follows:
(1) preparation of sample to be tested: Sterility testing
The detection that Initial microorganisms content is carried out to sample carries out initial count to bacterium, yeast and mould.
(2) antibacterial test method: in-can preservation challenge experiment
In sample to be tested, inoculation pollution 7 kinds of bacterium (inoculum concentrations 10 of common industrial class7Cfu/ml Tao Shi) is then sampled
4CC method (in CTFA method as prototype) carries out multiple challenge experiment, i.e., multiple inoculated bacteria (weekly, carrying out 4 weeks)
Re-test sample system content of microorganisms, to investigate the anti-microbial property of sample protective system.
(3) standards of grading of content of microorganisms
The standards of grading of 2 content of microorganisms of table
