Abstract

1. 청구범위에 기재된 발명이 속하는 기술분야1. TECHNICAL FIELD OF THE INVENTION

본 발명은 시멘트몰탈의 첨가제로서 사용되는 가소제의 제조방법에 관한 것이다.The present invention relates to a method for producing a plasticizer for use as an additive for cement mortar.

2. 발명이 해결하고자 하는 기술적 과제2. Technical problem to be solved by the invention

종래의 가소제의 제조방법 보다 경제적으로 유리하고 보다 효과적인 가소제를 제조하는데 그 기술적 과제가 있는 것이다.There is a technical problem in producing a plasticizer that is more economically advantageous and more effective than the conventional method for producing a plasticizer.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

핏치를 황산으로 설포네이션시키고 포름알데히드로 축합시킨후 수산화나트륨으로 중화시킴에 있어서, 핏치 1중량부에 대하여 황산 0.7 내지 1.5중량부 및 포름알데히드 0.05 내지 0.12중량부의 비율로 반응시키는 가소제의 제조방법 임.In the process of sulfonation with sulfuric acid, condensation of formaldehyde and neutralization with sodium hydroxide, a method of preparing a plasticizer is made by reacting sulfuric acid at a ratio of 0.7 to 1.5 parts by weight of sulfuric acid and 0.05 to 0.12 parts by weight of formaldehyde with respect to 1 part by weight of pitch. .

4. 발명의 중요한 용도4. Important uses of the invention

콘크리트 레미콘등의 제조 및 운반시에 공기연행성이 좋은 가소제를 사용함으로써 콘크리트 몰탈의 운반의 용이성을 도모하고 시공후 콘크리트의 강도를 강화시키는데 사용됨.It is used to facilitate the transport of concrete mortar and to reinforce the strength of concrete after construction by using plasticizer with good air continuity when manufacturing and transporting concrete ready concrete.
