KC-150泡沫穩定劑

    本產品為硅一碳鍵耐水解型勻泡劑,是一種聚硅氧烷一聚醚共聚物表面活劑,專門應用于各種聚酯型硬質泡沫塑料的勻泡劑。它適用于對苯二甲酸聚酯、已二酸聚酯等各種聚酯中,是在KC-888基礎上又成功研制開發的新一代產品,是國內首創的唯一的用于聚酯中的新型優良勻泡劑。

一、性能
  KC-150對聚酯(聚醚)與F11,水等具有極優良的乳化能力及良好的溶解性,可保證發泡物料混合均勻,保持長時間不分層,使泡沫塑料產品的泡孔細小、均勻、整體密度分布均勻、制品強度高、導熱系數小的特點。
  使用本產品可大大增加聚酯在發泡配方中的用量(以100份聚酯、聚醚總量為例,聚酯可增加到50~80份),從而大大降低泡沫塑料的成本。
  本產品的使用方法與一般勻泡劑的使用方法相同,不需要改變配方和工藝。
  本產品使用量100份白料(聚酯、聚醚)為2-3份。

三、應用:
  1.用于制造隔熱板的配方中:
  隔熱板的配方經常含有普通多元醇類及加強極性的特殊多元醇類,例如聚酯類多元醇。使用這些混合物的主要原因有二項:成本經濟和較佳的阻燃性能。然而,這些極性的多元醇由于與氟碳化合物起泡劑的混合性較差,從而引起樹脂預混合料的不勻質性。

KC-150 Foam Stabilizer
 This product is a silicon-carbide-bond anti-hy-drolytic foam stabilizer, a surfactant of polysiloxane polyether copolymer. It is especially used for manufacturing rigid polyester cellula plastic and used in various polyesters such as terephthalic acid polyester and adipic acid polyester. It is a newer product developed from KC-888 and a unique foam stabilizer used in polyester in China.

Ⅰ.Performance:
 KC-150 have excellent emulsifng ability for polyester and F11 ,water etc. and excellent solubl]ity in polyester or polyether.
 It can make fine, evenly-distributed cell in cellula plastic products which have high mechanical strength and low heat-conduction.
 The application of this product can greatly increase the dose of polyester in the foam formula (polyester to be added into the mixture of polyester and polyether can be increased by 50 to 80%). Thus the cost of cellula plastic can be greatly reduced.
 The usage of this product is the same as that of other common foam stabilizer, without changing any formula or process.
 2 or 3 portions of this product is added into 100 portions of the mixture of polyester and polyether.

Ⅲ.Application:

 1.Used in the formula to make sandwich boards The formula for making sandwich boards consists
of common polyol and special polar-reinforced polyol,for example, polyester polyol. These mixtures can reduce the cost and increase the fire resistance, However,these polar polyol can cause the unevenness of the premixed resin because of the poor ability of fluorocaronic bubbling agent.

  KC-150的乳化能力已在下列預合料中進行過多次試驗,這些預混合料沒有表面活性劑(勻泡劑)是不均質的,但在加入KC-150(2-3份)后,預混合料在室溫下貯存幾星期后仍不會分離;旌狭铣煞萑缦;

用上述混合料與粗的二異氰酸酯在指數(110)下制成的泡沫塑料,具有細致和規則的泡孔結構,但同樣的上述混合料在與其它表面活性劑(勻泡劑)配合使用時,其結果如下表:

  2.應用于一般的普通板料巾,可大大降低生產成本,(聚酯比例增大,可達80%),所得制品泡孔細小且均勻,密度分布均勻(而其它國產勻泡劑根本不能使用,聯碳公司的5340亦不行)。

四、貯存與使用注意事項:
(參見KC-888)

五、包裝與貯存:
  1.包裝:200kg鍍鋅鐵桶,凈重200kg。
  2.貯運:本品無毒、無腐蝕,應貯放在密閉干燥處,貯存期12個月。

 The emulsifying ability of KC-150 has been tried and proved many times in the following pre-mixed plastic materials ,that is ,the components in pre-mixed plastic materials are not evenly distributed without the addition of surfactant. But ,after KC-150(2 or 3 portions)is added ,the pre-mixed plastic materials can not be separated after several weeks of storage at indoor temperature.
The components of the pre-mixed materials are as follow(calculated in weight):
50 portions of sucrose polyol
50 portions of polyester
10 portions of fire retardant
2.5 portions of DMCHA
1 portions of water
2.5 portions of KC-150
40 portions of F
11

 
The cellula plastic made of the above materials and raw isocyanate under the index of 110 can have fine and regular cell. But the same above materials used with other surfactants (foam stabilizer) will have the following results:

2. The application in the common sandwich boards can greatly reduce the production cost (The proportion of polyester is increased by 80%). The cell are fine and evenly distributed and at the same time the density is also evenly distributed. (Other domestic foam stabilizer can not work nor can L5340).

IV. Storage and Precautions:
(See KC-888)

V. Packing and Storage:
1. Packing: 200kg galvanized iron pail. 200kg in net weight.
2. Storage: The product is of non-toxic and non-corrosiveness. It should be stored in airtight and dry place. The storge period will be twelve months.
