Contamination inhibitor composition
To provide a contamination inhibitor composition capable of effectively inhibiting pitch contamination on a dry part. The present invention is a contamination inhibitor composition 1 which is imparted to a dry part D of a paper-making machine, and comprising a film forming agent and a gelling agent, wherein the film forming agent is an emulsion consisting of water, a modified silicone and an emulsifier and the gelling agent is a compound represented by the following formula (1): [in the formula (1), R 1 each independently represents a hydrogen atom, a hydroxyl group, a carboxyl group or a hydrocarbon group optionally having a substituent having 1 to 3 carbon atoms, R 2 each independently represents a hydroxyl group or a carboxyl group, R 3 represents a hydrogen atom, a hydroxyl group or a carboxyl group, m is an integer of 1 to 5, and n is an integer of 0 to 5.].
1. A contamination inhibitor composition which is imparted to a dry part of a paper-making machine,
and comprising a film forming agent and a gelling agent,
wherein said film forming agent is an emulsion consisting of water, a modified silicone and an emulsifier,
said gelling agent is at least one selected from the group consisting of gluconic acid, malic acid and citric acid, and
the emulsifier is at least one selected from the group consisting of a nonionic surfactant, an anionic surfactant, a cationic surfactant and an ampholytic surfactant,
wherein said modified silicone is an amino-modified silicone having an amino group, a neutralizing agent for neutralizing the amino-modified silicone is further contained, and the neutralizing agent is acetic acid or lactic acid.
2. The contamination inhibitor composition according to claim 1 , wherein said gelling agent is gluconic acid.
3. The contamination inhibitor composition according to claim 1 , wherein a blending ratio is a ratio of a mass of the gelling agent to a mass of the modified silicone, and a range of said blending ratio is 0.01 to 2.
4. A contamination inhibitor composition which is imparted to a dry part of a paper-making machine,
and comprising a film forming agent and a gelling agent,
wherein said film forming agent is an emulsion consisting of water, a modified silicone and an emulsifier,
said gelling agent is at least one selected from the group consisting of gluconic acid, malic acid and citric acid, and
the emulsifier is at least one selected from the group consisting of a nonionic surfactant, an anionic surfactant, a cationic surfactant and an ampholytic surfactant,
wherein said modified silicone is an amino-modified silicone having an amino group, a neutralizing agent for neutralizing the amino-modified silicone is further contained, and the neutralizing agent is acetic acid or lactic acid,
wherein a blending ratio is a ratio of a mass of the gelling agent to a mass of the amino-modified silicone, and a range of said blending ratio is 0.01 to 0.02.
5. The contamination inhibitor composition according to claim 4 , wherein said gelling agent is gluconic acid.
