Description
Technical field
The invention belongs to building material fields, further relate to functional powder of lacquer putty for use on, and in particular to the waterproof that low temperature environment uses
Powder of lacquer putty for use on and its preparation process.
Background technology
Powder of lacquer putty for use on is a kind of material of decoration property of smooth surface of wall, and painting, which is imposed on priming paint or directly applied, imposes on metope
On, to remove the rugged defect of metope.The construction environment of traditional putty cannot be below 5 DEG C, when temperature is too low, Puttying
Afterwards, exterior wall putty coating is difficult to parch, wherein unevaporated moisture freezes, into after March, with the raising of temperature, ice is opened
Begin to melt, moisture is oozed out from wall, makes putty cracking, peeling, and after moisture is thoroughly dried, putty just falls off.In addition, existing
There is technology, mostly using cement as the binder of powder of lacquer putty for use on, at low cost, adhesion strength is higher, but toughness and tensile strength are relatively low, special
It is not putty bursting by freezing phenomenon easily occur in cold winter.
In the northern area of China, winter outdoor temperature is generally at -20 DEG C hereinafter, especially Daxing'an Mountainrange northern area, winter
Ji Wendu, although in March annual November to next year, carries out central heating, indoor environment temperature is made to be maintained at most down to -50.5 DEG C
In relatively comfortable range, but under heat transfer process, indoor heat can shift to outdoor generation, scatter and disappear, and need burning more
The energy go maintain room temperature stability room can obviously reduce by thermal insulation medium protective action in metope thermal insulation material
Interior thermal loss.
In conclusion producing, a kind of frost-cracking-preventing ability is strong, impervious strong, good heat preservation performance can construct in low temperature environment
Powder of lacquer putty for use on is required at present solves the problems, such as.
