产品作用原理mechanism

一、6-氨基-1,3-二甲基尿嘧啶(简称DMAU)作用原理:

熔点高达290℃以上,200℃加热减量<1%,本身特性能够适应PVC生产过程。?DMAU能吸收PVC生产过程

中产生的HCl,还能取代不稳定的Cl原子。与ZnSt2共同使用时,?DMAU能与ZnCl2发生反应,生成金属络合

物,使ZnCl2失去活性,能防止“锌烧”,大大增强PVC样品的长期稳定性;DMAU中主要基团尿嘧啶是人体

必需的四种核苷酸之一,对人体安全无害;DMAU因此被认为是高效且安全的热稳定剂;

A.?Mechanism:

with?melting?point?of?more?than?290degC,?loss?on?drying?under?200degC?of?less?than?1%,?it?suits?for?

PVCs?producing?process.?Can?absorb?HCl?which?is?by-produced?during?producing?process?of?PVC,?can?replace?Cl-?which?is?not?stable.?When?be?used?with?

ZnSt2,?can?react?with?ZnCl2?to?create?metal?complex,?then?ZnCl2?losses?its?activity,?so?can?avoid?PVCs?

color?from?changing?into?darker,?improve?PVCs?long?term?stability;?Its?basic?chemical?structure?uracil’?is?

one?of?the?essential?nucleotides?of?the?human?body,?has?no?hazardous?to?human;?So?it?is?taken?as?PVC?

heat?stabilizer?of?high-efficiency?and?safety;

二、DMAUZnSt2:

含有DMAU/ZnSt2复合稳定剂,无论初期白度还是长期稳定性都比含有CaSt2/ZnSt2复合稳定剂的更好。

DMAUZnSt2共同使用时具有良好的系统稳定效果,比目前工业上常用的的协同效果更好;

B.?DMAU?and?ZnSt2:

Stabilizer?of?DMAU/ZnSt2?is?better?than?stabilizer?of?CaSt2/ZnSt2?on?both?initial?whiteness?and?long?term?

stability;?DMAU/ZnSt2?is?of?systematic?stability,?its?efficiency?is?better?than?that?of?CaSt2/ZnSt2,?which?is?

of?synergistic?stability;

三、?DMAU与水滑石(或沸石):

DMAU与水滑石(或沸石,沸石更节省成本)同时使用,在钙锌稳定剂的配方中,加入3-4%DMAU

8-10%的水滑石或沸石,能更好地抑制PVC初期着色度,该配方更加经济可靠;

C.?DMAU?and?Hydrotalcite(or?Aluminosilicate):

To?add?3-4%?of?DMAU?and?8-10%?hydrotalcite(or?Aluminosilicate,?whose?cost?is?lower)?into?Calcium/Zinc?stabilizer,?it?can?improve?

PVCs?initial?colorless,?and?is?more?economic;

四、DMAU与β-二酮:

DMAU与β-二酮都是新兴的有机稳定剂,两者单独进行比较,DMAU在抑制初期着色和长期热稳定性方面

都能更胜一筹。实际生产过程中DMAU既可以完全替代β-二酮,也可以与β-二酮共同使用;

D.?DMAU?and?Stearoyl?benzoyl?methane:

DMAU?can?improve?PVCs?initial?colorless?and?long?term?heat?stability,?so?is?Stearoyl?benzoyl?methane;

?when?preparing?PVC?stabilizer,?DMAU?can?replace?stearoyl?benzoyl?methane,?DMAU?can?be?used?together?

with?stearoyl?benzoyl?methane?also;

五、DMAU发展历程:

DMAU应用于PVC稳定剂的技术早是由美国Chemtura研发,其将DMAU广泛的应用于其各种无铅稳定剂的

配方中。随着对铅盐稳定剂的限制,DMAU作为无铅稳定剂中的新星。新华制药是国内外大的DMAU

生产商。

E.?History?of?DMAU:

The?world?main?producers?of?PVC?stabilizer?are?cooperating?with?us.?Accompany?more?and?more?countries

?forbid?to?use?lead?salts?PVC?stabilizer,?it?will?be?used?more?and?more?widely;?We?are?the?leading?
